Sorted by total logical reads or total CPU time, it quickly surfaces the queries doing the most work. This script, adapted from the DBA-Scripts collection by Bulent Gucuk, combines <code>sys.dm_exec_query_stats</code> with <code>sys.dm_exec_sql_text</code> and <code>sys.dm_exec_query_plan</code> to return the query text and execution plan alongside the performance metrics — giving you everything needed to begin tuning in a single result set.</p>
