/* Description  : Written to avoid using sp_lock or sp_lockinfo sps. Those sps  */
/*                are not very flexible & sp_lockinfo hangs if tempdb itself is */
/*                locked. This SP also provides more filters to use. Blocking   */
/*                info. or blocked by info. is not available here. Only locks   */
/*                apart from the executing SPID will be shown. This SP gets     */
/*                blocked too if there is a long running transaction. (NOLOCK   */
/*                hint can avoid this.) Object names have been defaulted to 50  */
/*                characters. If you have predominantly names >50, increase the */
/*                display format accordingly. I designed the SP in such a way   */
/*                that it will eliminate the @@SPID for the current under which */
/*                you are calling. This can be modified if need be. This SP also*/
/*                avoids using  CURSORS or TEMPORARY TABLES to minimize the     */
/*                impact on other processes.                                    */
