Optional output parameter sql server 2017


I have a stored procedure that has a bunch of input and output parameters because it is Inserting values to multiple tables. Optional output parameter sql server 2017 some cases the stored proc only inserts to a single table (depending on the input parameters). If I run the without the optional parameter it works fine. If you specify the OUTPUT keyword for a parameter in the procedure definition, the stored procedure can return the current value of the parameter to the calling program when the stored procedure exits.

To save the value of the parameter in a variable that can be used in the calling program, the calling program must use the OUTPUT keyword when executing the stored procedure. The following example shows a stored procedure with an input and an output parameter.

You can use table-valued parameters to send multiple rows of data to a Transact-SQL statement or a routine, such as a stored procedure or function, without creating a temporary table or many parameters.Table-valued parameters are like parameter arrays in OLE DB and ODBC, but offer more flexibility and closer integration with Transact-SQL.

Table-valued parameters also have the benefit of being able to participate in set-based operations.Transact-SQL passes table-valued parameters to routines by reference to avoid making a copy of the input data. You can create a stored procedure with optional parameters by specifying a default value for optional parameters. When the stored procedure is executed, the default value is used if no other value has been specified.Specifying default values is necessary because a system error is returned if a parameter does not have a default value specified in the stored procedure and the calling program does not provide a value for the parameter when the stored procedure is executed.If no value can be specified appropriately as a default for the parameter, you can specify NULL as the default for a parameter and have the stored procedure return a customized message if the stored procedure isTHIS TOPIC APPLIES TO: SQL Server (starting with 2008) Azure SQL Database Azure SQL Data Warehouse Parallel Data WarehouseReturns one row for each parameter of a user-defined function or stored procedure that can be accessed by the current user in the current database.
