Let me now think about your proposal and read the numRowsAffected documentation:
[quote]
Returns the number of rows affected by the result's SQL statement, or -1 if it cannot be determined. Note that for SELECT statements, the value is undefined; use size() instead.

Yeah, there's still a little difference between reading documentation and understanding documentation...

For anyone with the same problem, I used to get the rows length with:
@query->record().count()@
I hope may help someone.

Hi and welcome to devnet,
Row length and row count are not the same thing. The row length is the number of field in the row, while the row count is the number of row returned by your query.
