Introduction
In this article I am going to explain about how to declare parameter in stored procedure. We use CREATE PROC statement to create a stored procedure with parameter. We use @ sign to declare a parameter. We put @ sign before parameter name then type of parameter. Type of parameter can be any valid SQL data type.
There are two type of parameter
- Input parameter
- Output parameter
Input parameter passed in stored procedure by user at calling time. Output parameter return some value to calling program.
A Statement that create invoices table
