I'm transforming a query from .select(offset=start, limit=rpp) to .query()[:] syntax. ('rpp' means records per page.) Stupidly I transformed it directly into:
.query()[start:rpp] which in one transaction evaluates to: .query()[1420:20] This causes a SQL syntax error with the actual query containing: ... LIMIT -1400 OFFSET 1420 Apparently a negative limit is illegal in MySQL. Of course I should have done it this way: .query()[start:start+rpp] because the second number is supposed to be one past the last index, not the number of records to return. This results in a much more reasonable: .query()[1420:1440] ... LIMIT 20 OFFSET 1420 My point is, if the second number is lower than the first, shouldn't SQLAlchemy transform it into a query that returns no records? I.e., LIMIT 0, which MySQL at least allows. Because that's what the Python equivalent would do: >>> range(9999)[1420:20] [] -- Mike Orr <[EMAIL PROTECTED]> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
