DELETE with a non-INT WHERE condition on an INT column fails

If I delete an escaped statement that contains a single quotation mark through Java PreparedStatements it is deleted in InnoDB tables but not in ColumnStore tables.

The injection seems fine though.

I attached Java example code to reproduce the bug.

Please change the server credentials according to your setup.
I used a remote connection from Windows 10 to CS on Ubuntu 18.04.

Error string that is not deleted in CS:

ab';CREATE TABLE pwnd (i int) engine=columnstore; -- 

Output of the demo:

number of rows in inno_escape before insert: 0

number of rows in cs_escape before insert: 0

number of rows in inno_escape after insert: 1

number of rows in cs_escape after insert: 1

number of rows in inno_escape after delete: 0

number of rows in cs_escape after delete: 1
