Subject [jira] Updated: (DERBY-4066) Allow functions/procedures to take Blob/Clob arguments
Date Fri, 23 Jul 2010 18:29:53 GMT

Rick Hillegas updated DERBY-4066:
---------------------------------

    Attachment: derby-4066-01-ak-enableLobArgs.diff

Attaching derby-4066-01-ak-enableLobArgs.diff. This is a re-warmed version of the patch.

In addition to bringing the patch up to date with the current state of the trunk, this patch
adds some new test cases to verify the setting of LOB function args using ? parameters. These
new tests fail, so the patch is not ready for commit.

Also, more tests are needed to examine the behavior of procedure arguments. As currently coded,
the patch should still forbid the declaration of LOB output procedure arguments.

I believe that the problem with ? CLOB args is backed up behind DERBY-4754.

> Derby objects if you try to declare a function or procedure with an argument whose type
is BLOB or CLOB. These kinds of arguments are allowed in the SQL standard and the matching
Java types are java.sql.Blob and java.sql.Clob. See the SignatureMatching.html summary attached
to DERBY-3652.
> We should lift this restriction and allow functions and procedures to take large object
arguments.
