An error has occurred in the TNG software. What to do:

If you just installed an upgrade, you might have skipped part of the installation instructions. Go back to the upgrade readme page reread the instructions. Pay special attention to the database structure step.

If you just installed TNG for the first time, you might still need to create the database tables. Return to the readme.html page to find that step.

If you are the site owner, you may contact TNG support for further assistance with this problem. Please copy the query below and paste it into your message.



Query: SELECT f.familyid, f.husband AS Husband_ID, f.wife AS Wife_ID, f.marrdate, c.personID AS Child_ID, f.living, f.gedcom, changedby FROM tng_families AS f LEFT OUTER JOIN tng_children AS c ON c.familyID = f.familyID WHERE ( ( f.husband LIKE 'I%' =0 ) OR ( f.husband = '-' ) OR ( f.wife LIKE 'I%' =0 ) OR ( f.wife = '-' ) ) AND c.personID IS NULL ORDER BY c.personID, f.familyID LIMIT 50

The SELECT would examine more than MAX_JOIN_SIZE rows; check your WHERE and use SET SQL_BIG_SELECTS=1 or SET MAX_JOIN_SIZE=# if the SELECT is okay
