This Question brings a situation where the Query Optimizer chooses poorly the seek predicate among the existing predicates of a simple query. After running some tests I got to the conclusion that the poor decision is due to the use of a local temp table instead of a global temp table or a regular table.
db fiddle: Local Temp Table, Global Temp Table, Regular Table.
I couldn't find any characteristic on the Temporary Tables doc that would explain the different behavior we see when using a local temporary table instead of a global temporary table or a regular table. Is there a logical reason for this or could it be a bug?
