Sql server - SQL Call Stored Procedure for each Row without using a cursor

If you need to call a stored procedure for each row in a result set without using a cursor, you can leverage the CROSS APPLY operator in SQL Server. This allows you to invoke a table-valued function, stored procedure, or an expression for each row returned by a query.

Here is an example using a stored procedure:

Assuming you have a stored procedure named YourStoredProcedure that takes a parameter and you want to call it for each row in a table called YourTable, you can use the CROSS APPLY operator as follows:

-- Example stored procedure CREATE PROCEDURE YourStoredProcedure @Parameter INT AS BEGIN -- Your stored procedure logic here -- Use the @Parameter as needed PRINT 'Called YourStoredProcedure with parameter: ' + CAST(@Parameter AS NVARCHAR(MAX)); END; -- Example table CREATE TABLE YourTable ( ID INT PRIMARY KEY, YourColumn INT ); -- Insert some sample data INSERT INTO YourTable (ID, YourColumn) VALUES (1, 100), (2, 200), (3, 300); -- Call the stored procedure for each row in YourTable SELECT t.ID, t.YourColumn FROM YourTable t CROSS APPLY YourStoredProcedure(t.YourColumn) AS ca;

In this example:

  • YourStoredProcedure is a sample stored procedure that takes an INT parameter.
  • YourTable is a sample table with an ID column and YourColumn column.

The CROSS APPLY operator is used to call the stored procedure for each row in YourTable, passing the YourColumn value as a parameter.

Make sure to replace YourStoredProcedure, YourTable, and other placeholders with your actual stored procedure name, table name, and column names. Adjust the stored procedure and parameter types accordingly to match your specific scenario.

Examples

  1. "SQL Server Execute Stored Procedure for Each Row in Table"

    • Execute a stored procedure for each row in a table without using a cursor.
    -- Example: Using a SELECT statement SELECT column1, column2 FROM your_table CROSS APPLY your_stored_procedure(column1);

  2. "SQL Server Execute Stored Procedure for Each Row in Result Set"

    • Execute a stored procedure for each row in the result set of a query without using a cursor.
    -- Example: Using a common table expression (CTE) WITH ResultSet AS ( SELECT column1, column2 FROM your_table ) SELECT column1, column2 FROM ResultSet CROSS APPLY your_stored_procedure(column1);

  3. "SQL Server Execute Stored Procedure for Each Row with Parameters"

    • Execute a stored procedure for each row with parameters without using a cursor.
    -- Example: Using a table variable DECLARE @TempTable TABLE ( column1 INT, column2 INT ); INSERT INTO @TempTable (column1, column2) SELECT column1, column2 FROM your_table; SELECT column1, column2 FROM @TempTable CROSS APPLY your_stored_procedure(column1);

  4. "SQL Server Execute Stored Procedure for Each Row with Output"

    • Execute a stored procedure for each row and capture the output without using a cursor.
    -- Example: Using OUTPUT parameters DECLARE @OutputTable TABLE ( column1 INT, output_column INT ); INSERT INTO @OutputTable (column1, output_column) EXEC your_stored_procedure; SELECT column1, output_column FROM @OutputTable;

  5. "SQL Server Execute Stored Procedure for Each Row in Temp Table"

    • Execute a stored procedure for each row using a temporary table without using a cursor.
    -- Example: Using a temporary table CREATE TABLE #TempTable ( column1 INT, column2 INT ); INSERT INTO #TempTable (column1, column2) SELECT column1, column2 FROM your_table; SELECT column1, column2 FROM #TempTable CROSS APPLY your_stored_procedure(column1);

  6. "SQL Server Execute Stored Procedure for Each Row in Subquery"

    • Execute a stored procedure for each row in a subquery without using a cursor.
    -- Example: Using a subquery SELECT column1, column2 FROM ( SELECT column1, column2 FROM your_table ) AS Subquery CROSS APPLY your_stored_procedure(column1);

  7. "SQL Server Execute Stored Procedure for Each Row in APPLY Operator"

    • Execute a stored procedure for each row using the APPLY operator without using a cursor.
    -- Example: Using the APPLY operator SELECT column1, column2 FROM your_table CROSS APPLY your_stored_procedure(column1) AS ProcedureResult;

  8. "SQL Server Execute Stored Procedure for Each Row with Row_Number()"

    • Execute a stored procedure for each row using the ROW_NUMBER() function without using a cursor.
    -- Example: Using ROW_NUMBER() SELECT column1, column2 FROM ( SELECT column1, column2, ROW_NUMBER() OVER (ORDER BY some_column) AS RowNum FROM your_table ) AS NumberedRows WHERE RowNum = 1;

  9. "SQL Server Execute Stored Procedure for Each Row with CROSS JOIN"

    • Execute a stored procedure for each row using a CROSS JOIN without using a cursor.
    -- Example: Using CROSS JOIN SELECT column1, column2 FROM your_table CROSS JOIN your_stored_procedure(column1);

  10. "SQL Server Execute Stored Procedure for Each Row with VALUES Clause"

    • Execute a stored procedure for each row using the VALUES clause without using a cursor.
    -- Example: Using VALUES clause SELECT column1, column2 FROM VALUES (1, 'value1'), (2, 'value2'), (3, 'value3') AS ValueRows (column1, column2) CROSS APPLY your_stored_procedure(column1);
