I try to use group_concat with SEPARATOR option as it was proposed in other
topic but got a strange issue with using group_concat and op:
this expression:
print node.urlname.op('SEPARATOR')('/')
gives
node.urlname SEPARATOR :urlname_1
But this expression
print func.group_concat(node.urlname.op('SEPARATOR')('/'))
gives
group_concat((node.urlname SEPARATOR :urlname_1))
and these extra brackets in real query cause SQL error. Is there anything I
am doing wrong?
Thanks a lot in advance!
