Description
The reproducer is cumbersome, because the SP definition contains "\0" symbol and mysqltest apparently doesn't like it or converts it into something else. Maybe you'll find a better way to write it. Meanwhile, please copy the one-line attachment into /tmp dir, and then run this as a regular MTR:
--exec $MYSQL --binary-mode < /tmp/mdev32481.sql
|
CALL test.sp();
|
|
|
# Cleanup
|
DROP PROCEDURE test.sp; |
Alternatively, you can add CALL test.sp() directly into mdev32481.sql and run it via the client.
