An example message from this:
There should be no remaining tmp_trino tables that are queryable. They are:
For queryId [20230310_183735_00015_ii5en] (prefix [tmp_trino_31f5781f_]) remaining tables: [tmp_trino_31f5781f_14b3eb70]
With errors: [
Expecting code to raise a throwable.]
For queryId [20230310_183738_00020_ii5en] (prefix [tmp_trino_5ce0903c_]) remaining tables: [tmp_trino_5ce0903c_2f4304bc]
With errors: [

Very nice, much better than what I came up with.
LGTM. Can you add a stress test with just the MySQL FTE tests having 30 runs. I was able to get it to fail around 1 in 10 times against MySQL.

Nice, looks good to go. Please don't forget to revert the MySQL changes (I just wanted them to make sure the change is effective before merging). |

Description
This fixes the issue described in #16277
Because
information_schemais not strictly consistent with recently dropped tables among all connectors, but querying recently dropped tables is consistent, this no longer relies onSHOW TABLES LIKEreturning no results, but instead, actually attempts to query the recently dropped temporary table, and expects there to be a "does not exist" exception.Additional context and related issues
