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

I update the @Zohar answer. Define blank is bad habits, ideally define with null and later use blank. So the query will be

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

Even I like the @Biswa answer as it use current version of sql server, but Sqlserver 2008R2 does not have this function.
