Change max count field in GROUP BY
I install mysql with: ./configure --prefix=/usr/local/mysql --with-max-indexes=32
sql_const.h:#define MAX_REF_PARTS 32U
I can create a table with the number of indexes more than 15, but I can't use the it fields in GROUB BY, only max 15 fields:
The mysql error is: able storage engine for '/tmp/mysql0/#sql_2c7e_0' doesn't have this option
How I must to use configure options or change the MySQL constants
