Hi,

I have an application usin= g embedded derby (10.8.1.2). In the program I use a little routine that end= s with rollback, commit or nothing at all, by using a parameter.

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

But I get then always an E= xception:

 

Eine Verbindung ka= nn nicht beendet werden, solange noch eine Transaktion aktiv ist.

   =    at org.apache.derby.impl.jdbc.SQLExceptionFactory= 40.getSQLException(Unknown Source)

&nb= sp;     at org.apache.derby.impl.jdbc.Util.newEmbedSQLE= xception(Unknown Source)

&nb= sp;     at org.apache.derby.impl.jdbc.EmbedConnection.n= ewSQLException(Unknown Source)

&nb= sp;     at org.apache.derby.impl.jdbc.EmbedConnection.c= heckForTransactionInProgress(Unknown Source)

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

 

That obviously is the code 25001

 

Even though I initialize a= ll my prepared statements that also are inserts and updates, in this mode o= nly a select statement is used.

How come I get such a Exce= ption. It seems that I have to commit or rollback always I quit a derby pro= gram even though no change has occurred on particular database<= /o:p>

 

Or is there something I sh= ould care about?
