Hi everyone, am I the only one that have the feeling that the database engine has changed in the last two/three weeks ? I have queries that previously worked fine in production (for 3 years already!) and suddenly return no results or errors. The similarity between these queries is a comparaison with a null value. Where I previously had something like «  custsomething = null » in my where conditions, I now have to use « custsomething is null ». I am not saying that the = null was the correct way to do it, but I find it strange that all of a sudden I have so many issues. And they seem to have appeared after the pre-release maintenance. Am I going crazy here ? (Note, I have seen this behavior on multiple accounts, unrelated to each other)

Haven't noticed, but do you happen to know if the affected accounts were upgraded to 2024.1?

They were not but all of them had the pre-upgrade maintenance

@Loïc Beaujean we had the same problem. SQL in portlet just stopped working due to maintenance on production account (SB hadn't been updated and was working fine) they fixed in a couple days.

I had queries starting to time out after the maintenance update. My pet theory is that they didn't recreate all indexes properly but its just a guess.
