Kathey Marsden closed DERBY-3583.
---------------------------------
Resolution: Won't Fix
With Kristian's alternate DERBY-2892 patch this won't be necessary as multiple
calls will still be allowed.
> Derby should throw a better error message if a BLOB/CLOB column is accessed
> more than once

> Key: DERBY-3583

> Project: Derby
> Issue Type: Improvement
> Reporter: Kathey Marsden
> Assignee: Kathey Marsden
> Priority: Minor
>
> With the DERBY-2892 fix revision 642974, users can no longer access a
> BLOB/CLOB column more than once for each row. Currently the error message is
> XJ217 - You cannot invoke other java.sql.Clob/java.sql.Blob methods after
> calling the free() method or after the Blob/Clob's transaction has been
> committed or rolled back.
> I don't know that that makes sense given the user called getString()
> For getCharacterStream()/getBinaryStream() there is no error on the call,
> just an IOException on the read.
> We should throw a clearer error message, that the user is not allowed to make
> multiple getXXX calls on a BLOB/CLOB column for each row.
