问题 If I have an MS Access database with linked tables from two different database servers (say one table from an SQL Server db and one from an Oracle db) and I write a query which JOINs those two tables, how will Access (or the Jet engine, I guess?) handle this query? Will it issue some SELECTs on each table first to get the fields I'm JOINing on, figurre out which rows match, then issue more SELECTs for those rows? 回答1: The key thing to understand is this: Are you asking a question that Access
