Hello Monty, I'm done with: MDEV-10577 sql_mode=ORACLE: %TYPE in variable declarations But I'd like to move a certain part of MDEV-10577 into a separate patch. I created an MDEV entry for this: MDEV-11245 Move prepare_create_field and sp_prepare_create_field() as methods to Column_definition Can you please review it? See attached. There's also a copy here: hasky.askmonty.org:/tmp/MDEV-11245.diff The patch is for 10.3. Thanks.
