![]() Use BULK INSERT to load data from text file. Use tables to hold the data or pass string parameters formatted as CSV, XML, JSON (or any other convenient format) and then parse the parameters before the INSERT statement. Use the output of the stored procedure as input to an INSERT statement. See the preceding example for a workaround. Use declared table type user-defined parameters. Use INOUT instead of OUT for bidirectional parameters. IN and OUT|OUTPUT, by default OUT can be used as IN as well.Īlthough the functionality of these parameters is the same for SQL Server and MySQL, make sure that you rewrite the code for syntax compliance. Unlike SQL Server, OWNERs can’t be specified and must be explicitly named. IN is the parameter direction for both MySQL and SQL Server.įor stored procedures that use an explicit user name, rewrite the code from EXECUTE AS 'user' to DEFINER = 'user' and SQL SECURITY DEFINER.įor stored procedures that use the CALLER option, rewrite the code to include SQL SECURITY INVOKER.įor stored procedures that use the SELF option, rewrite the code to DEFINER = CURRENT_USER and SQL SECURITY DEFINER. Rewrite stored procedure parameter direction OUTPUT to OUT or INOUT for bidirectional parameters. Add parentheses around the parameter declaration. Rewrite stored procedure parameters to not use the symbol in parameter names. Rewrite stored procedure creation scripts to omit the AS keyword. Rewrite stored procedure creation scripts to use PROCEDURE instead of PROC. The following table summarizes the differences between MySQL Stored Procedures and SQL Server Stored Procedures. SELECT * FROM OrderItems įor the preceding example, the result looks as shown following. Select all rows from the OrderItems table. VALUES (var_OrderID, var_Item, var_Quantity) Ĭall the stored procedure. INSERT INTO OrderItems (OrderID, Item, Quantity) INTO var_OrderID, var_Item, var_Quantity ) INSERT INTO SourceTable (OrderID, Item, Quantity)Ĭreate a procedure to loop through all rows in SourceTable and insert them into the OrderItems table. CREATE TABLE OrderItemsĬreate and populate SourceTable as a temporary data store for incoming rows. Use a LOOP cursor with a source table to replace table valued parameters.Ĭreate the OrderItems table. CREATE PROCEDURE ProcessImportBatch()ĬALL Step1 Step2 Step3 error_count > 1 ![]() Replace RETURN value parameter with standard OUTPUT parameters. It’s typically used to signal status or error to the calling scope, which can use the syntax EXEC = to retrieve the RETURN value, without explicitly stating it as part of the parameter list. When you use this feature, only the first row in the data set returned by the stored procedure is evaluated.Īs part of the stored procedure syntax, SQL Server supports a default output integer parameter that can be specified along with the RETURN command, for example, RETURN -1. ![]() SQL Server provides a unique feature that allows you to use a stored procedure as an input to an INSERT statement. They can be explicitly recompiled for every run using the RECOMPILE option and can be encrypted in the database using the ENCRYPTION option to prevent unauthorized access to the source code. In SQL Server, you can run stored procedures in any security context using the EXECUTE AS option. You can specify parameters as both IN and OUT. IN is the default direction for parameters, but OUT must be explicitly specified. Table-valued user-defined types canīe used as input parameters. They may have multiple input and output parameters. Stored procedures are encapsulated, persisted code modules you can run using the EXECUTE T-SQL statement.
