Re: ERROR 1168 when adding a table

Update on this, it seems to be related to the number of objects,
I combined two of the smaller tables and tried making a merge table with the 6 other tables and the combined table, it would only work when the number of objects
was less than 4*10^9. There isn't by chance a mediumint limit on the size of
merged tables hidden somewhere in the mysql code?
These tables also have a number of indexes just so all the info is out there I include the description below:
