Good afternoon,

I’m working with Genexus Ev3 Up1. I have a Data Provider that searches for a query and returns an SDT with the information, but of the error in TOMCAT with the message of:

java.sql.Sqlexception: Failed to convert to Internal representation.

In the database the query is normally generated, only in the application of the error.

Thank you.

java oracle genexus

  • Arthur, To better show you a way, I believe it is necessary more information: - Detail a little more "search for a query"? - What kind of object are you running? - Return an Sdt with the information to where? Anyway, it seems to me a database error. How did you verify that "In the database the query is generated normally"? The best way to verify the generated query is to open the source code of the object in question.

  • Thanks for the reply Sandro, after a good analysis I checked the error, it was in the same bank, the query generated normally, but had aggregated data with the oracle’s LISTAGG function that when converting to genexus gave the error, I fixed it and the problem was solved, thanks for your attention.
