PSQLException: current transaction is aborted, commands ignored until end of transaction block

Question

I am seeing the following (truncated) stacktrace in the server.log file of JBoss 7.1.1 Final:

Caused by: org.postgresql.util.PSQLException: 
ERROR: current t         


        

Answer 1

You need to rollback. The JDBC Postgres driver is pretty bad. But if you want to keep your transaction, and just rollback that error, you can use savepoints:

try {
_stmt = connection.createStatement();
_savePoint = connection.setSavepoint("sp01");
_result = _stmt.executeUpdate(sentence) > 0;
} catch (Exception e){
 if (_savePoint!=null){
 connection.rollback(_savePoint);
}
}
