SQLServer存储过程 | 易学教程

最基础的存储过程

新建存储过程

CREATE PROCEDURE PR_Sum12
AS
BEGIN
update formtable_main_122 set fzybcp = '4' WHERE requestid = 26275
END
go

修改存储过程

ALTER PROCEDURE PR_Sum12
AS
BEGIN
update formtable_main_122 set fzybcp = '6' WHERE requestid = 26275
END
go

执行存储过程

exec PR_Sum12

    close my_cursor_one
    deallocate my_cursor_one            
    close my_cursor_Two
    deallocate my_cursor_Two           
END
GO
