Hello, I’m having a problem with concurrent processing. 2 queries are accessing the same parent table that have 24 partitions. I see “shared lock is not granted “ for one of them on one of the children while the other query is running. Does the “ select from a parent table” make a lock on the children? How I can change it? The one of the queries runs hourly ( 8 min) on the server , the other one can be run by a user , and a few users can run the same query. Thank you.
