Dag H. Wanvik updated DERBY-4338:
---------------------------------
Attachment: derby-151-b.stat
derby-151-b.diff
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.
