Subject [jira] Updated: (DERBY-4338) Network client raises error "executeQuery method can not be used for update" when sql is preceded by /* */ comments
Date Mon, 31 Aug 2009 21:59:33 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4338?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Dag H. Wanvik updated DERBY-4338:

    Attachment: derby-151-b.stat

Uploading version "b" of this patch. 

- Changed severity to database; updated ErrorCodeTest to reflect this.
  Rationale: It seems right - I don't know that it's safe to continue
  after this kind of error, and I compared to other IO level errors in
  raw store and mostly seem to have database severity. 

- Made the new Derby151Test not fail even if expected error is not
  seen. I did this to allow for possible different behavior on other
  VMs, JUnit verbose mode would instead print "Not able to test fix
  for DERBY-151: No interrupt seen".

- I added the same handling to read (even if not seen yet) as for
  write.  Regressions passed modulo ErrorCodeTest, which i missed
  first time around.

- Fixed some broken Javadocs.

Ready for review.

> Network derby client does not properly detect a sql select statement preceded by /* */
comments.  As a result the sql appears to be detected as an update statement, and results
in  the following error:
>  org.apache.derby.client.am.SqlException: executeQuery method can not be used for update.
> 	at org.apache.derby.client.am.Statement.checkForAppropriateSqlMode(Unknown Source)
> 	at org.apache.derby.client.am.PreparedStatement.flowExecute(Unknown Source)
> 	at org.apache.derby.client.am.PreparedStatement.executeQueryX(Unknown Source)
> The problem appears to be in Statment.parseSqlAndSetSqlModes(), which only appears to
check for "--" style comments.
