Greetings!

I have a problem that it seems would best be solved using subqueries. However, I am working on a server that is running MySQL 3.23.58, so subqueries are not available to me.

What I am trying to do:
I have two tables, each containing approximately 37,000 records. I want to compare the index field in Table A to the index field in Table B. I would like to see all records where the index in Table A does not exist in Table B.


You want to select from A, not from B, yes?

SELECT a.* FROM foo AS a
LEFT OUTER JOIN bar AS b
ON a.index_field = b.index_field
WHERE b.index_field IS NULL;
