SELECT * FROM
WHERE (uppercol1, uppercol2) IN
(SELECT col1, col2 FROM subtable)
When writing them on provider 126.96.36.1996, they worked all right.
With the latest provider (188.8.131.520) they all fail to return data. No error message is given. Rolling back to the older version restores ability to run these queries.
I've been able to work around this by altering my queries but it would be great to have the option to use multiple columns back. If not possible, having a meaningful error message would be fantastic.
