Subject [jira] Commented: (DERBY-3687) Make client driver allow nested savepoints
Date Thu, 22 May 2008 22:23:55 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12599221#action_12599221
] 

Dag H. Wanvik commented on DERBY-3687:
--------------------------------------

Found this comment in Xact.java:

// SQL savepoint can't be nested inside other user defined savepoints. To 
// enforce this, we check if there are already user savepoint(SQL/JDBC)
// defined in the transaction. If yes, then throw an exception

So, does the client use the SQL version of savepoints (not documented), and that's
why they can't be nested? And if so, why?

> Currently, only the embedded driver allows nested savepoints, cf. the attached repro.
> In the interest of harmonizing the drivers it would be nice to make the client driver
allow this as well.
