I have a large table of records that need joined againts three other databases depending on database_name. example data:
pk db_name data 1 db1 whatever else 2 db1 whatever else 3 db3 whatever else 7 db2 whatever else 8 db2 whatever else 10 db1 whatever else
those primary keys may only exist on that one db that it needs retreived from, or it may even be taken by another file that doesnt match with my data, Im not really sure. So either way i need to make sure my join is only with the proper db.
I’ll also be doing this daily, multiple times so I’d like to skip the step of making 3 seperate tables for the query (though this could maybe be done in the query?)
In any case any suggestions here would be appreciated.
Edit: I’d like to stay away from any make / drop table queries if possible.
