Increase 32767 limit for "-528 Maximum output rowsize max-size exceeded."

Be more modern with your limits.
PostgreSQL does not have such a low limit.

    This RFE has been closed with status: "Not under Consideration". We understand this limit can affect clients: ODBC. JDBC, Python, PHP, etc. and most important, external (non IBM) drivers. But you can change internally all related variables from short type to unsigned short. And change all informix apps like dbaccess etc to work with this new sizes.

    This is doable step by step. because you can keep by default checking row size and throwing -528 exception if greater than 32767. This exception can be disabled or limit increased by an environment variable

    Next step, you can change the row size maximum size also in IBM products like JDBC and Client SDK.

    As row size limit is driven in engine (like now) throwing -527 exception you can keep this as default, and allow to set an environment variable to increase to 65,535 for supported clients.

    Lot of work, but It seams feasible, so we don't really understand why you changed status to "Not under consideration"

    I don't know why, but my user is not able to vote anymore. BTW I agree with you. Incresing all signed smallint limit is something Informix should do because new applications makes intensive use.

    I'll explain a real business case. We have a client application iterating in a database structure like: grandparent -> parent -> child -> child

    Childs can have some hundreds of rows. We use MULTISET as this is very very fast and we can get all data from the server in "one shot". Iterating programmatically from client to server has a lot of overhead getting data one by one.

    Another user case is using SPL for executing complex queries and calculations and return to client application a text with a JSON structured data.

    So we use MULTISETS or SPL for getting complex structures in "one shot" but 32k limit is a problem.

    I just posted a request for the same under the title "Lift 32K limit on SQL queries/results".  I kept searching for a similar idea and did not find it until I posted mine and the this one showed under "related ideas".   We need this as soon as possible.
