问题
Now, I'm pretty sure that it's not possible, but I want to 1) Confirm this, and 2) Hear alternatives.
My solution today was to run the MySQL query, then use its result to construct a "NOT IN ('value1', 'value2', 'value3')" string, which I tacked onto the Oracle query before running it. Rather cumbersome, but it worked, and it's fast enough so far.
What is the typical way of solving this problem?
回答1:
Typical way, assuming the Oracle & MySQL databases are allowed to talk to one another, would be to create a database link on the Oracle instance, connecting to the MySQL one: http://www.dba-oracle.com/t_how_create_database_link.htm
Then you can run queries in Oracle as though you're only ever working on a single database...
