The 'sort buffers' are actually from whichever cache your user tempdb is bound to, although I think there was something about the cache the table was bound to as well.....(there was a change in one of...

The sort buffers from proc cache are the buffers used to actually process the sort operation. The worktable itself to hold the results will be stored in the assigned tempdb's cache, this uses buffers...

Thanks Simon and Jeff for clarifying about the sort buffers and procedure cache. The code is working on about 9000 rows each - (x 150 procs) so am rather surprised that I need more than 25Gb cache. Is...

The 1500s errors I think always refer back to the regular sort manager and reports error in not enough tempdb buffers or proc cache buffers for the sort, the latter just used during the processing for...

For me I don't think it will make a huge amount of difference to plan choice unless you don't have in place non-sampled densities. When you update statistics with sampling the pages and values it reads...

Thanks Gaurav! dbcc checkcatalog showed up some orphaned records in syscolumns and sysindexes. I removed these manually, recreated the dump and was able to load it in to the 16.0 server. Regards,Paul

I think this is likely due to the parameterization of the literals within the substring clause, I'm not sure the behaviour has changed. Maybe you have statement cache/literal_autoparam enabled on...

If you are on 15.7sp130+, use update statistics with hashing instead of update statistics with sampling. My opinion is that it is more accurate than sampling and definitely would eliminate the issue...
View ArticleRe: update Index Stats using Sampling
Definitely agree that you should move to hash-based stats but I would very strongly recommend to not do this in production without going through some significant testing in UAT. It is much more stable...
