Insert or update query executed successfully but data are not persistent

Question

I'm trying to insert or update elements in an existing firebird database using JDBC. I access to the database with the default credentials (SYSDBA and masterkey).

The request are done successfully according JDBC but database are not modified (when I execute a select my data does not appear). I also tried to modify the database content using a software as RazorSQL, the result is the same (the database are modified during the session but if I disconnect and reconnect to the database my modifications are lost).

I anybody has an idea how to solve this problem?

Thanks in advance

Answer 1

Most likely you are running with autoCommit disabled. In that case you need to explicitly call commit() on the Connection. Also be aware that a transaction can only see changes from transactions that were committed before it started.

See also the Jaybird JDBC Driver Java Programmer's Manual, chapter "Using transactions".
