SQL Server 2008 R2: Prepare Dynamic WHERE Clause

Question

I have the following stored procedure with four parameters.

Stored procedure spTest:

CREATE PROCEDURE spTest
    @Name varchar(20) = \'\         


        

Answer 1

It's called catch-all queries and it basically goes like this:

CREATE PROCEDURE spTest
    @Name varchar(20) = '',
    @Address varchar(100) = '',
    @City varchar(50) = '',
    @Pin varchar(50) = ''
AS
    SELECT * 
    FROM Test_Table 
    WHERE (@Name = '' OR Name = @Name)
    AND (@Address = '' OR Address = @Address)
    AND (@City = '' OR City = @City)
    AND (@Pin = '' OR Pin = @Pin);
GO
