MDL_MYSQL_SERVER_VERSION |
||
The framework uses MySQL version number to determine whether SQL92
JOIN statements can be used; if not, the corresponding clause is added
to the WHERE clause. This is because MySQL servers up to 4.0 do not
handle JOIN statements in a standard way, making it impossible to
generate a valid SQL query when more than 2 joins are involved.
If the environment variable is left unset, it defaults to the value returned
by MySQLdb.get_client_info() . |
'3.23' , '4.0' , 4.0.11a-gamma (see at end of
description for the default value) |
