When we create function we can use default value for parameters if we need so, is there any way to create a procedure with default value parameter in SQL Server so when we don’t pass the value for that parameter they can use default values? Yes, we can. In this article we will create procedure with default parameter value.
Let's see default template provided by microsoft:
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author: <Author,,Name> -- Create date: <Create Date,,> -- Description: <Description,,> -- ============================================= CREATE PROCEDURE <Procedure_Name, sysname, ProcedureName> -- Add the parameters for the stored procedure here <@Param1, sysname, @p1> <Datatype_For_Param1, , int> = <Default_Value_For_Param1, , 0>, <@Param2, sysname, @p2> <Datatype_For_Param2, , int> = <Default_Value_For_Param2, , 0> AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; -- Insert statements for procedure here SELECT <@Param1, sysname, @p1>, <@Param2, sysname, @p2> END GO
Now let's create a simple procedure in SQL Server
CREATE PROCEDURE SearchProducts @Category varchar(50) ,@PriceUpto DECIMAL(18,2) AS SELECT P.* FROM Products P WHERE P.Category = @Category AND P.Price <= @PriceUpto
We created a procedure SearchProducts when we need to use it or test it we always have to provide the category and price, say
EXEC SearchProducts 'Toys', 50.00
Now let's say we want to create a procedure with default category 'Toys' and Price upto 50.00 then we need to change our procedure like this
CREATE PROCEDURE SearchProducts @Category varchar(50) = 'Toys' ,@PriceUpto DECIMAL(18,2) = 50.00 AS SELECT P.* FROM Products P WHERE P.Category = @Category AND P.Price <= @PriceUpto
Notice at the time of creating the parameter we also provided some values which will be used as a default value, If now we want to test/execute our procedure then simply we can use
And it will use 'Toys' for category parameter and 50.00 for Price upto parameter.
