[Koha-devel] Out of sort memory, consider increasing server sort buffer size

[Jonathan Druart]

Hi Philippe,

See bug 21622.
It is necessary to not explode with "$field is not in group by" (when
sql_mode has ONLY_FULL_GROUP_BY)
However we may need to discuss the need of this flag if it brings us
performance issues.

Cheers,
Jonathan
