Subject Does derby ned allways a rollback or commt?
Date Tue, 22 Nov 2011 11:08:52 GMT

I have an application using embedded derby ( In the program I use a little routine
that ends with rollback, commit or nothing at all, by using a parameter.

In a certain mode I just do a select, so As far I concern I don't need to do neither rollback
nor commit, since it is just a select.

But I get then always an Exception:


Eine Verbindung kann nicht beendet werden, solange noch eine Transaktion aktiv ist.

      at org.apache.derby.impl.jdbc.SQLExceptionFactory40.getSQLException(Unknown Source)

      at org.apache.derby.impl.jdbc.Util.newEmbedSQLException(Unknown Source)

      at org.apache.derby.impl.jdbc.Util.newEmbedSQLException(Unknown Source)

      at org.apache.derby.impl.jdbc.Util.generateCsSQLException(Unknown Source)

      at org.apache.derby.impl.jdbc.EmbedConnection.newSQLException(Unknown Source)

      at org.apache.derby.impl.jdbc.EmbedConnection.checkForTransactionInProgress(Unknown

      at org.apache.derby.impl.jdbc.EmbedConnection.close(Unknown Source)


That obviously is the code 25001


Even though I initialize all my prepared statements that also are inserts and updates, in
this mode only a select statement is used.

How come I get such a Exception. It seems that I have to commit or rollback always I quit
a derby program even though no change has occurred on particular database


Or is there something I should care about?
