A stored procedure can be used to which the Search Type and Search Value are passed as arguments as shown below

SQL

CREATE PROCEDURE dbo.SearchData (@SearchType NVARCHAR(100), @SearchValue NVARCHAR(100))
AS
BEGIN

DECLARE @FilterExp NVARCHAR(250)
SET @FilterExp = CASE @SearchType
    WHEN 'Name' THEN 'WHERE Name = ''' + @SearchValue + ''''
    WHEN 'SerialNumber' THEN 'WHERE SerialNumber = '''+ @SearchValue + ''''
    WHEN 'All' THEN ' '
    END
Exec( 'SELECT * FROM tbluser ' + @FilterExp )
END

Then to call

SQL

EXEC dbo.SearchData 'Name','UserName'
