SQL Server Stored Procedure - UPDATE - Example
Source code to create and add sql update stored procedure to catalog
The following example is for creating a simple update stored procedure. You can run it through an explicit call from a host language program or directly from a DBMS query execution shell like SQL Server Management Studio or dbOrchestra.
CREATE PROCEDURE dbo.sp_Students_UPD_byPK @active_flg TINYINT = NULL , @student_id INT AS BEGIN SET NOCOUNT ON UPDATE dbo.Students SET active_flg = ISNULL(@active_flg , active_flg) FROM dbo.Students WHERE student_id = @student_id END GO
It is important to note that for every column you include in the update code you will need to enter data for. Typically, an sql update stored procedure would be created for all the columns. There would be a mapping layer that moves existing data to the exposed variables. In the example provided I have created an update stored procedure that could be tied directly to a function that would activate or inactivate a student. Having an sql update stored procedure for this type of activity is wholly rational and appropriate.
Executing the sql update stored procedure
Execute sql update stored procedure
To run the stored procedure you need to supply a values to the applicable variables.
-- @active_flg IN TINYINT -- @student_id IN INT EXEC dbo.sp_Students_UPD_byPK @active_flg = 0 , @student_id = 23
