EGL problem with DB2 Warnings

There's a problem with DB2 Warnings in EGL, because they're been
treated like errors, not like warnings.

It's a little difficult to reproduce the problem because i haven't been
able to get a DB2 warning on purpose, but we've got this problem twice
in a production enviroment.

The warning we get in this case is 437 (it's warning because it's not
negative) which means that "Performance of this complex query may be
sub-optimal."

The problem is that EGL is treating this warning as an error, the query
does run and it goes to the "onException" clause.

GetDeprDocsCenteraList exception EGL0502E EGL0502E OPEN: error[sqlstate:
01602][sqlcode:437]

Function GetDeprDocsCenteraList(ctx Contexto, listSpec
ListSpecification, listOut deprDocsCentera[] out)

try
// Prepare the dynamic SQL statement to retrieve the data
prepare selectStatement from "SELECT ....";

// Open the cursor on the above dynamic SQL Select statement.
open resultSet with selectStatement;
onException (exception SQLException)
ExcepcionesGestionaException(ctx, "GetDeprDocsCenteraList",
exception);
end
