Greetings,
we recently did upgrade our project from version 5.x.x unidac to 6.2.9 , after a while we stumbled on some few problems updating and working on tables with OID's set to true getting error "Overflow while converting variant of type (Int64) into type (Integer)", I am kinda surprised why unidac components are trying to retrieve oids as type integer, as-long as I can recall working with postgres, oids always where type bigint hence Int64.
Bug - Postgresql tables with OID's
Re: Bug - Postgresql tables with OID's
We have checked functionality of UniDAC using PostgreSQL tables with OID's. Unfortunately, we couldn't reproduce the issue. Please compose a complete demo sample reproducing the issue, and send it to us, including a script for creating all the used database objects, for further investigation.
