Does SELECT SLEEP(0) INTO @dummy work for Xpand DB? That syntax suggestion came from gopigment@b548db4#diff-22f5eec5ea345b8f0fd8c96f47bb2a7e59d35071c7ad2525d6f251a5ece19d5cR319.

works fine!

If applied to library, when will it be released?

[bgrainger]

The SELECT SLEEP(0) INTO @dummy syntax is also a necessary workaround for SingleStore (see memsql@d8f808e) so it seems reasonable to make it the default in MySqlConnector.

Fixed in 2.1.5.

This syntax may not be compatible with Manticore: #1356.
