	This script displays your most resource-intensive queries from the plan cache,
	and points to ways you can tune these queries to make them faster.

	To learn more, visit http://FirstResponderKit.org where you can download new
	versions for free, watch training videos on how it works, get more info on
	the findings, contribute your own code, and more.

	Known limitations of this version:
	 - @IgnoreQueryHashes and @OnlyQueryHashes require a CSV list of hashes

               - The plan is estimated-only (nothing to recalc).
               - The plan has more than 500 RelOps. Each RelOp costs two .modify() calls
                 (a delete plus an insert), and every .modify() rewrites the whole
                 document, so the cap bounds a single plan to ~1,000 rewrites - roughly
                 a second of CPU on a big plan. Plans over the cap still get the
                 attribute/element stripping above and whitespace minification below;
                 they only keep their original cumulative row-mode timings.
               - NodeId values are not unique across the document. NodeId is only
                 unique within a single statement, so on multi-statement plans
                 (stored procedures, batches) //p:RelOp[@NodeId=...] would mix
                 operators from different statements: the math would blend unrelated

' + CASE WHEN QueryType LIKE N'Statement (parent%' THEN N' The above query is part of a batch, stored procedure, or function, so other queries may show up in the query plan. However, those other queries are irrelevant here. Focus on this specific query above, because it is one of the most resource-intensive queries in the batch. The execution plan below includes other statements in the batch, but ignore those and focus only the query above and its specific plan in the batch below. ' ELSE N' ' END + N'
