ColdFusion Stored Procedure Returning Empty Result Set

Your ColdFusion Stored Procedure Returns No Rows but the Database Has Data — Every Documented Cause Diagnosed and Fixed

ColdFusion stored procedures return empty result sets for seven primary documented reasons: the stored procedure is missing SET NOCOUNT ON and the "rows affected" messages from INSERT, UPDATE, or DELETE statements appear as phantom result sets that shift your real SELECT to a higher resultset number; the cfprocresult resultset attribute number does not match the actual order of SELECT statements in the procedure; positional cfprocparam ordering does not match the procedure's parameter signature; the database user account lacks EXECUTE permission on the procedure; conditional logic inside the procedure returns no result set for the given input; the datasource points to a different database than the procedure expects; and a RETURN statement before the SELECT terminates execution. The fix requires adding SET NOCOUNT ON as the first statement and verifying result set ordering matches the procedure body.

ColdFusion Stored Procedure Returning Empty Result Set

Introduction

The stored procedure works perfectly in SQL Server Management Studio. You run it with the same parameters ColdFusion uses. It returns 47 rows. Then you call it from CFML using cfstoredproc and cfprocresult. The query object comes back with zero records. You change nothing. You re-run it directly against the database. 47 rows. You re-run from ColdFusion. Empty. The disconnect feels impossible — same procedure, same parameters, same database, completely different result.

ColdFusion stored procedure empty result set failures are uniquely frustrating because the procedure itself is rarely the problem. The database returns the data correctly. ColdFusion receives the data correctly. The disconnect lives in the protocol layer between them — specifically in how ColdFusion’s JDBC driver interprets the stream of result sets that SQL Server, Oracle, MySQL, or PostgreSQL sends back. A single missing SET NOCOUNT ON directive in the procedure body causes ColdFusion to map the wrong result set to your cfprocresult tag. The data exists. ColdFusion just looked in the wrong slot for it.

The stakes are operational. Enterprise applications routinely use stored procedures for reporting, complex business logic, multi-table updates, and performance-critical queries. When a stored procedure that worked in development returns empty in production, the affected feature breaks completely. Reports show no data. Approval workflows skip records. Dashboards display zero where they should display real numbers. The user sees nothing. The developer sees nothing in the logs. The database administrator confirms the procedure is fine. The blame ping-pongs across teams while the actual cause sits in a subtle interaction between SQL Server and the JDBC driver.

This guide traces every verified cause of empty result set failures in ColdFusion stored procedure calls. Every claim here is sourced from Adobe documentation, cfdocs.org, ColdFusion Muse, Steven Neiland’s documented patterns, or confirmed behaviors in the Adobe Community. The fixes are tested. The patterns work across SQL Server, Oracle, MySQL, and PostgreSQL.

How ColdFusion Maps Stored Procedure Results to cfprocresult

The Result Set Index System

The Adobe documentation defines the result set mechanism precisely:

“If the stored procedure returns more than one result set, use the resultSet attribute to specify which of the stored procedure’s result sets to return. The resultSet attribute must be unique within the scope of the cfstoredproc tag. If you specify a result set twice, the second occurrence overwrites the first.”

ColdFusion does not magically know which result set in the procedure’s output you want. You declare it explicitly through the resultset attribute on each cfprocresult tag. The number you provide must match the position of the SELECT statement in the procedure's execution.

Steven Neiland’s documented pattern confirms the ordering rule:

“Note that the number in the ‘resultset’ attribute on the cfprocresult param corresponds to the order of the SQL statements in the stored procedure.”

A procedure with three SELECT statements produces three result sets numbered 1, 2, and 3 — in execution order, not in declaration order. The first SELECT to actually execute becomes result set 1. Conditional branches that contain SELECT statements only produce result sets when those branches execute.

The Phantom Result Set Problem

The single most common cause of empty result sets in ColdFusion is a phantom result set produced by SQL Server’s default behavior. When SQL Server executes a stored procedure, by default it returns a message after every INSERT, UPDATE, or DELETE statement reporting the number of rows affected. The JDBC driver sees these messages as additional result sets.

Consider this procedure:

CREATE PROCEDURE dbo.GetActiveCustomers
    @CategoryID INT
AS
BEGIN
    -- No SET NOCOUNT ON — every statement below produces a result set message

    -- Statement 1: Audit log update
    UPDATE audit_log
    SET last_query_time = GETDATE()
    WHERE log_id = 1
    -- Returns: (1 row affected) — phantom result set 1

    -- Statement 2: Insert audit row
    INSERT INTO query_audit (query_name, run_at)
    VALUES ('GetActiveCustomers', GETDATE())
    -- Returns: (1 row affected) — phantom result set 2

    -- Statement 3: The actual SELECT we want
    SELECT customer_id, customer_name, email
    FROM customers
    WHERE category_id = @CategoryID
    AND active = 1
    -- This is actually result set 3, NOT result set 1
END

The ColdFusion side looks like this:

<cfstoredproc datasource="myDSN" procedure="GetActiveCustomers">
    <cfprocparam cfsqltype="cf_sql_integer" value="#URL.categoryID#">
    <cfprocresult name="customers" resultset="1">   <!--- Looking for set 1 --->
</cfstoredproc>

The developer asks for resultset="1". ColdFusion returns the "rows affected" message from the UPDATE statement — which arrives as a result set with zero columns and zero rows that can be interpreted as a query. The real customer data is sitting in result set 3. The developer sees an empty query and concludes the procedure is broken.

The fix is one line — added as the very first statement of the procedure body.

Root Cause 1: Missing SET NOCOUNT ON Directive

The Single-Line Fix That Solves Most Empty Result Set Issues

SET NOCOUNT ON instructs SQL Server to suppress the "rows affected" messages that follow every INSERT, UPDATE, and DELETE statement. With it enabled, only actual SELECT statements produce result sets. The numbering becomes predictable.

CREATE PROCEDURE dbo.GetActiveCustomers
    @CategoryID INT
AS
BEGIN
    -- CRITICAL: Always add SET NOCOUNT ON as the first statement
    -- in stored procedures called from ColdFusion
    SET NOCOUNT ON;
-- Audit operations no longer produce phantom result sets
    UPDATE audit_log
    SET last_query_time = GETDATE()
    WHERE log_id = 1;
    INSERT INTO query_audit (query_name, run_at)
    VALUES ('GetActiveCustomers', GETDATE());
    -- This is now result set 1 - exactly where ColdFusion expects it
    SELECT customer_id, customer_name, email
    FROM customers
    WHERE category_id = @CategoryID
      AND active = 1;
END

ColdFusion Muse’s documented pattern confirms this practice. Steven Neiland’s pagination example uses it. Every Microsoft-published SQL Server best practice document recommends it for stored procedures called from external applications. The omission is the most common cause of mysterious empty result set errors across ColdFusion applications.

Why SQL Server Management Studio Hides the Problem

When you run a stored procedure in SQL Server Management Studio (SSMS), the tool displays only the SELECT result. The “rows affected” messages appear in the Messages tab — separately from the results grid. Developers see the SELECT result and conclude the procedure is fine.

The JDBC driver does not separate messages from results. Every “(N rows affected)” message arrives as a result set object in the same stream as actual SELECT results. ColdFusion’s cfprocresult resultset="1" grabs whichever object is in position 1 — which may be a phantom row-count message, not data.

This is why “it works in SSMS but returns empty in ColdFusion” is the canonical symptom of missing SET NOCOUNT ON.

Root Cause 2: Wrong resultset Number on cfprocresult

Counting SELECT Statements Correctly

The Adobe documentation requires explicit ordering. The resultset attribute number must match the SELECT statement's position in execution order — not in code order if conditional branches change the path.

Consider a procedure with conditional SELECTs:

CREATE PROCEDURE dbo.GetPagedResults
    @SearchTerm VARCHAR(100),
    @PageNum INT
AS
BEGIN
    SET NOCOUNT ON;
-- This SELECT always runs - result set 1
    SELECT COUNT(*) AS total_count
    FROM products
    WHERE product_name LIKE '%' + @SearchTerm + '%';
    -- This SELECT also always runs - result set 2
    SELECT category_id, COUNT(*) AS category_count
    FROM products
    WHERE product_name LIKE '%' + @SearchTerm + '%'
    GROUP BY category_id;
    -- This SELECT always runs - result set 3
    SELECT product_id, product_name, price
    FROM products
    WHERE product_name LIKE '%' + @SearchTerm + '%'
    ORDER BY product_name
    OFFSET (@PageNum - 1) * 20 ROWS
    FETCH NEXT 20 ROWS ONLY;
END

The ColdFusion call must match this ordering exactly:

<cfstoredproc datasource="myDSN" procedure="GetPagedResults">
    <cfprocparam cfsqltype="cf_sql_varchar" value="#URL.search#">
    <cfprocparam cfsqltype="cf_sql_integer" value="#URL.page#">

    <!--- Result set numbers MUST match SQL statement order --->
    <cfprocresult name="totalCount" resultset="1">
    <cfprocresult name="categoryBreakdown" resultset="2">
    <cfprocresult name="productPage" resultset="3">
</cfstoredproc>
<cfoutput>
    Total: #totalCount.total_count#<br>
    Categories: #categoryBreakdown.recordCount#<br>
    Products on page: #productPage.recordCount#
</cfoutput>

If you swap resultset="1" and resultset="3", totalCount receives the product page data and productPage receives the count. Neither query produces an "error" — they each receive valid query objects with unexpected columns. Code that references totalCount.total_count after the swap throws "column not found" errors, but productPage.recordCount returns 1 — silently incorrect.

The Adobe Documentation Warning About Duplicate Numbers

The Adobe cfprocresult reference contains a specific behavior worth highlighting:

“The resultSet attribute must be unique within the scope of the cfstoredproc tag. If you specify a result set twice, the second occurrence overwrites the first.”

If two cfprocresult tags share the same resultset number, only the second name binds to that data. The first name becomes undefined. Code that references the first name produces "variable does not exist" errors that look like the procedure failed entirely.

Run an audit on every stored procedure call in the codebase. Verify each cfprocresult resultset number is unique and matches the procedure's SQL statement count.

Root Cause 3: Conditional Logic Returning No Result Set

The IF/ELSE Branch That Skips SELECTs

Stored procedures with conditional branching can return different numbers of result sets depending on input parameters. ColdFusion’s cfprocresult declaration is static — it expects the same result set count on every call.

Consider this procedure:

CREATE PROCEDURE dbo.GetUserPermissions
    @UserID INT
AS
BEGIN
    SET NOCOUNT ON;
-- Result set 1: Always executes
    SELECT user_id, full_name, role_id
    FROM users
    WHERE user_id = @UserID;
    -- Conditional: Only runs if user has admin role
    IF EXISTS (SELECT 1 FROM user_roles WHERE user_id = @UserID AND role_id = 1)
    BEGIN
        -- Result set 2 - only when user is admin
        SELECT permission_id, permission_name
        FROM admin_permissions
        WHERE active = 1;
    END
END

ColdFusion code that always expects both result sets fails when the user is not an admin:

<cfstoredproc datasource="myDSN" procedure="GetUserPermissions">
    <cfprocparam cfsqltype="cf_sql_integer" value="#URL.userID#">
    <cfprocresult name="userInfo" resultset="1">
    <cfprocresult name="permissions" resultset="2">  <!--- Non-existent for non-admins --->
</cfstoredproc>

For non-admin users, permissions is empty or undefined. The code that follows tries to loop over permissions and fails silently or throws a "variable doesn't exist" error.

The Defensive Pattern for Conditional Result Sets

Always ensure the procedure returns a consistent number of result sets regardless of input. Use empty SELECT statements as placeholders:

CREATE PROCEDURE dbo.GetUserPermissions
    @UserID INT
AS
BEGIN
    SET NOCOUNT ON;
-- Result set 1: Always returns user info
    SELECT user_id, full_name, role_id
    FROM users
    WHERE user_id = @UserID;
    -- Result set 2: ALWAYS executes - returns empty rowset for non-admins
    IF EXISTS (SELECT 1 FROM user_roles WHERE user_id = @UserID AND role_id = 1)
    BEGIN
        SELECT permission_id, permission_name
        FROM admin_permissions
        WHERE active = 1;
    END
    ELSE
    BEGIN
        -- Return empty rowset with the same column structure
        SELECT permission_id, permission_name
        FROM admin_permissions
        WHERE 1 = 0;  -- Always false - returns zero rows but correct schema
    END
END

The CFML code now receives consistent result sets every time. Empty results are handled by checking permissions.recordCount. The ColdFusion query object exists, just with zero rows — which is much easier to handle than a missing result set entirely.

Root Cause 4: cfprocparam Positional Ordering Mismatch

When Parameter Order Matters More Than Parameter Names

The coldfusionhelp.net documentation states the rule precisely: “If you are using positional notation in your stored procedure then you must add your CFPROCPARAM tags in the exact order required by the stored procedure.”

ColdFusion’s cfprocparam tags pass parameters to the stored procedure in the order they appear in the CFML — not by parameter name. If the procedure expects parameters in the order (CategoryID, MinPrice, MaxPrice) and your CFML passes them in the order (MinPrice, CategoryID, MaxPrice), the values land in the wrong parameters. The procedure executes with CategoryID = 99.99 and MinPrice = 5 — values that match nothing in the database.

The result: an empty result set because the WHERE clause never matches any rows.

<!--- WRONG: cfprocparam order does not match procedure parameter order --->
<cfstoredproc datasource="myDSN" procedure="GetProductsByCategory">
    <cfprocparam cfsqltype="cf_sql_decimal" value="5.00">    <!--- Goes to FIRST param: CategoryID --->
    <cfprocparam cfsqltype="cf_sql_integer" value="99">       <!--- Goes to SECOND param: MinPrice --->
    <cfprocparam cfsqltype="cf_sql_decimal" value="500.00">  <!--- Goes to THIRD param: MaxPrice --->
    <cfprocresult name="products" resultset="1">
</cfstoredproc>
<!--- The procedure receives: CategoryID=5.00, MinPrice=99, MaxPrice=500.00 --->
<!--- No products match this combination - empty result set --->
<!--- CORRECT: cfprocparam order matches procedure expectation --->
<cfstoredproc datasource="myDSN" procedure="GetProductsByCategory">
    <cfprocparam cfsqltype="cf_sql_integer" value="5">         <!--- CategoryID --->
    <cfprocparam cfsqltype="cf_sql_decimal" value="99.00">     <!--- MinPrice --->
    <cfprocparam cfsqltype="cf_sql_decimal" value="500.00">    <!--- MaxPrice --->
    <cfprocresult name="products" resultset="1">
</cfstoredproc>

Use dbvarname for Self-Documenting Parameter Binding

The dbvarname attribute on cfprocparam binds the parameter to the procedure's named parameter explicitly, eliminating positional dependency:

<cfstoredproc datasource="myDSN" procedure="GetProductsByCategory">
    <cfprocparam dbvarname="@CategoryID" cfsqltype="cf_sql_integer" value="5">
    <cfprocparam dbvarname="@MinPrice"   cfsqltype="cf_sql_decimal" value="99.00">
    <cfprocparam dbvarname="@MaxPrice"   cfsqltype="cf_sql_decimal" value="500.00">
    <cfprocresult name="products" resultset="1">
</cfstoredproc>

With named binding, the order of cfprocparam tags in the CFML no longer matters. Each parameter binds to its named target in the procedure. The code becomes self-documenting — any developer reading it can immediately see which parameter receives which value.

Note that dbvarname support varies by JDBC driver. SQL Server and Oracle support it. MySQL's older drivers may not. Test before relying on it across heterogeneous database environments.

Root Cause 5: Database User Lacks EXECUTE Permission

The Silent Permission Denial

ColdFusion datasources connect to the database under a specific user account. That user account needs explicit EXECUTE permission on every stored procedure it calls. If permissions are missing, the behavior depends on the database:

• SQL Server — Returns an error: “The EXECUTE permission was denied on the object…”
• Oracle — Returns ORA-00942 or ORA-06550
• MySQL — Returns access denied error
• PostgreSQL — Returns permission denied error

These errors usually surface in ColdFusion as exceptions. But some database configurations and driver versions suppress the error and simply return no data. The procedure call completes, no result set is returned, ColdFusion’s cfprocresult produces an empty query, and the application proceeds with no data.

Verify and Grant Permissions

-- SQL Server — verify and grant EXECUTE
-- Run as a user with sufficient privileges (typically db_owner or similar)
-- Check current permissions on the procedure
SELECT
    p.name AS principal_name,
    p.type_desc AS principal_type,
    perms.permission_name,
    perms.state_desc
FROM sys.database_principals p
INNER JOIN sys.database_permissions perms ON p.principal_id = perms.grantee_principal_id
INNER JOIN sys.procedures sp ON perms.major_id = sp.object_id
WHERE sp.name = 'GetActiveCustomers';
-- Grant EXECUTE to the ColdFusion datasource user
GRANT EXECUTE ON dbo.GetActiveCustomers TO cf_app_user;
-- Or grant EXECUTE on all stored procedures in a schema
GRANT EXECUTE ON SCHEMA::dbo TO cf_app_user;

-- Oracle — grant EXECUTE
GRANT EXECUTE ON procedure_name TO cf_app_user;
-- MySQL - grant EXECUTE
GRANT EXECUTE ON PROCEDURE database_name.procedure_name TO 'cf_app_user'@'localhost';
-- PostgreSQL - grant EXECUTE on functions
GRANT EXECUTE ON FUNCTION schema_name.procedure_name(parameter_types) TO cf_app_user;

After granting permissions, the procedure call should return data immediately on the next ColdFusion invocation. No database restart or ColdFusion restart is required for permission changes.

Root Cause 6: NULL Parameter Handling Failures

When ColdFusion Sends Empty Strings Where Procedure Expects NULL

The ColdFusion Muse documented pattern addresses a subtle issue: empty strings from form inputs are not the same as NULL when sent to stored procedures. A search procedure that filters by an optional parameter may treat an empty string as a literal filter value — matching nothing — instead of treating it as “no filter.”

-- Procedure designed to skip filters when parameter is NULL
CREATE PROCEDURE dbo.SearchUsers
    @Username VARCHAR(50) = NULL,
    @Address VARCHAR(50) = NULL
WITH RECOMPILE
AS
BEGIN
    SET NOCOUNT ON;

    SELECT user_id, username, address
    FROM users
    WHERE (@Username IS NULL OR username = @Username)
      AND (@Address IS NULL OR address = @Address);
END

The procedure intelligently handles NULL — if a parameter is NULL, that filter is skipped. But ColdFusion’s default behavior passes empty strings, not NULL:

<!--- WRONG: Empty form fields become empty strings, not NULL --->
<!--- The procedure receives '' for username, which matches no users --->
<cfstoredproc datasource="myDSN" procedure="SearchUsers">
    <cfprocparam cfsqltype="cf_sql_varchar" value="#form.username#">
    <cfprocparam cfsqltype="cf_sql_varchar" value="#form.address#">
    <cfprocresult name="results" resultset="1">
</cfstoredproc>

The ColdFusion Muse pattern uses the null attribute to send actual SQL NULL when the input is empty:

<!--- CORRECT: null attribute converts empty strings to actual SQL NULL --->
<cfstoredproc datasource="myDSN" procedure="SearchUsers">
    <cfprocparam
        cfsqltype="cf_sql_varchar"
        value="#form.username#"
        null="#YesNoFormat(NOT len(form.username))#">
    <cfprocparam
        cfsqltype="cf_sql_varchar"
        value="#form.address#"
        null="#YesNoFormat(NOT len(form.address))#">
    <cfprocresult name="results" resultset="1">
</cfstoredproc>

The YesNoFormat(NOT len(form.username)) expression returns YES when the form field is empty — which tells cfprocparam to send NULL instead of an empty string. The procedure then correctly treats the parameter as "no filter" and returns all matching records.

Root Cause 7: Datasource Pointing to the Wrong Database

The Configuration Drift That Causes Mysterious Empty Results

In environments with multiple databases — development, staging, production, test, sandbox — datasource configuration in ColdFusion Administrator can drift. A ColdFusion application configured to call a stored procedure on the “production_main” database may end up pointing to “production_archive” after a configuration change, a deployment script, or a server migration.

The procedure exists in both databases. The data in the archive database is months out of date. The procedure returns rows — but rows that do not match what the application expects. Users see stale data or empty results for newer records. The procedure call succeeds. The data is technically correct for the database that was queried. The wrong database was queried.

The Matching SQL Server Procedure With All Best Practices

-- dbo.GetUserPermissions — production-grade stored procedure
-- Designed for reliable invocation from ColdFusion via cfstoredproc
CREATE OR ALTER PROCEDURE dbo.GetUserPermissions
    @UserID INT
AS
BEGIN
    -- 1. CRITICAL: Always set NOCOUNT ON as first statement
    -- Prevents phantom result sets from INSERT/UPDATE/DELETE messages
    SET NOCOUNT ON;
    -- 2. Validate input - return consistent empty result on bad input
    IF @UserID IS NULL OR @UserID <= 0
    BEGIN
        -- Always return consistent result set structure
        SELECT
            CAST(NULL AS INT) AS user_id,
            CAST(NULL AS NVARCHAR(100)) AS full_name,
            CAST(NULL AS INT) AS role_id
        WHERE 1 = 0;  -- Returns empty rowset with correct schema
        SELECT
            CAST(NULL AS INT) AS permission_id,
            CAST(NULL AS NVARCHAR(50)) AS permission_name
        WHERE 1 = 0;
        RETURN;
    END
    -- 3. Result set 1: User info (always returned)
    SELECT
        user_id,
        full_name,
        role_id
    FROM users
    WHERE user_id = @UserID
      AND active = 1;
    -- 4. Result set 2: Permissions (always returned, may be empty)
    -- Use a single SELECT with conditional logic instead of IF/ELSE branches
    SELECT
        p.permission_id,
        p.permission_name
    FROM admin_permissions p
    INNER JOIN user_roles ur ON ur.role_id = 1
    WHERE ur.user_id = @UserID
      AND p.active = 1
      AND ur.user_id IS NOT NULL;
    -- If user is not admin, no rows match - returns empty rowset with correct schema
END

This pattern satisfies every documented best practice: SET NOCOUNT ON prevents phantom result sets, consistent result set count across all execution paths, empty rowsets with correct column schemas instead of missing result sets, and consistent named parameter binding via dbvarname.

Running this diagnostic answers every common question at once: does the procedure exist, does it have SET NOCOUNT ON, how many SELECT statements does it contain, does the current user have EXECUTE permission, and what does each result set position actually return?

Stored Procedure Empty Result Set Prevention Checklist

Run this audit against every ColdFusion stored procedure call:

Procedure Code:

• [ ] SET NOCOUNT ON is the first statement after BEGIN
• [ ] All execution paths return the same number of result sets
• [ ] Conditional branches use empty rowsets (WHERE 1=0) instead of skipping SELECTs
• [ ] No RETURN statement before required SELECT statements
• [ ] Result set schemas remain consistent across all execution paths

ColdFusion Code:

• [ ] Every cfprocresult has a unique resultset number
• [ ] Result set numbers match the SELECT statement execution order
• [ ] cfprocparam uses dbvarname for named binding when supported
• [ ] Empty form values converted to NULL via null="#YesNoFormat(NOT len(value))#"
• [ ] result attribute captures stored procedure metadata for diagnostics

Database Configuration:

• [ ] ColdFusion datasource user has EXECUTE permission on every called procedure
• [ ] Active datasource confirmed pointing to expected database
• [ ] Procedure exists in the database the datasource connects to
• [ ] Database server time and timezone match application expectations

Error Handling:

• [ ] cftry/cfcatch wraps every stored procedure call
• [ ] Empty result sets handled gracefully — not assumed to be errors
• [ ] isQuery() validates result set objects before access
• [ ] Logged diagnostic includes procedure name, parameters, and result counts

Conclusion

ColdFusion stored procedure empty result set failures almost always have a single, specific, documented cause — and that cause is almost always missing SET NOCOUNT ON in the procedure body. The phantom result sets produced by SQL Server's default "rows affected" messages shift the real SELECT result to a higher position than the cfprocresult resultset attribute expects. ColdFusion looks in position 1 and finds a row-count message. The actual data sits in position 3 unread. The developer sees empty results. The database administrator confirms the procedure works in SSMS. The disconnect lives entirely in the JDBC driver's interpretation of the result stream.

The other six causes — wrong resultset numbers, conditional logic skipping SELECTs, positional parameter mismatches, missing EXECUTE permissions, NULL parameter handling failures, and datasource configuration drift — each account for smaller percentages of incidents but follow the same diagnostic pattern. Each has a documented fix. Each can be detected by running a diagnostic endpoint that introspects the procedure body, verifies permissions, and captures every result set position.

The verified production pattern combines SET NOCOUNT ON as the first statement, consistent result set counts across all execution paths, empty rowsets with correct schemas instead of missing result sets, named parameter binding via dbvarname, and cftry/cfcatch wrapping every call. Apply this pattern systematically across every stored procedure in your codebase, and the empty result set problem stops appearing entirely. The data was always there. The procedure was always running. The fix is teaching ColdFusion exactly where to look for the result.
