The additional compiler property jopaz.compiler.esql.db2 signals the Jopaz compiler that the database used in the application is IBM Db2. The property is set to "1" (true) by default.

If you do not disable this property, the compiler generates specific code, which returns the result sets in the same format as the IBM Db2 precompiler. It supports the SQLDA structure and the use of date, time, and timestamp as function parameters.
