its possiblesomething like...WHERE (Field1=@Param1 OR @Param1 IS NULL)AND (Field2=@param2 OR @Param2 IS NULL)... make sure you set default values of parameters to NULLAlso for large datasets performance of above logic can be bad due to inefficient query plan formation.------------------------------------------------------------------------------------------------------SQL Server MVPhttp://visakhm.blogspot.com/ |

AND OR
