Hi,
I need to use substring function into sql statement. For it, I define
the next sql:
_sql = select([func.substring(planilladet.c.msg_debug, 1,
40).label('msg_debug'), func.sum(planilladet.c.cant).label('cant'),
func.sum(planilladet.c.cant * planilladet.c.importe).label('importe')],
\
from_obj=[planilladet.join(planilla)],
group_by=[1])
When I execute that sql, this error message appear:
(ProgrammingError) (-104, 'isc_dsql_prepare: \n Dynamic SQL Error\n
SQL error code = -104\n Token unknown - line 1, column 39\n ,')
'SELECT substring(planilladet.msg_debug, ?, ?) AS msg_debug,
sum(planilladet.cant) AS cant, sum(planilladet.cant *
planilladet.importe) AS importe \nFROM planilladet JOIN planilla ON
planilla.plan_id = planilladet.plan_id \nWHERE planilla.conv_id = ?
AND planilla.fec_imput = ? GROUP BY 1' [1, 40, 1, datetime.date(2008,
2, 1)]
What can be the problem here?
Thanks in advance.
