You can either commit or rollback the transaction when you encounter an SQL error. This will alow the next statements to execute successfully.

Hi,

I just find out that I cannot continue using a connection when I use
autocommit=false and that an sql insert failed.

In pseudo code this is what I'd like to do:

1) create connection
2) set autocommit = false
3) do an insert that succeed
4) do an insert that fails
5) catch the SQLException (I don't do a rollback on purpose)
6) do a select with the same connection
7) do another insert
8) commit

Everything goes well until step (6). where I receive the following error:

ERROR: current transaction is aborted, commands ignored until end of
transaction block
Exception: org.postgresql.util.PSQLException
org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:1525)
org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1309)
org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:188)
org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:452)
org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:354)
org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:258)

Can I do something is step (5) so that I don't get the error in step (6) ?
I need to continue using the same connection.

Thanks you your help.
