I tried your SQL statement in mysql command line it works for me.

mysql> SELECT CONCAT('My','\'', 'QL');
+-------------------------+
| CONCAT('My','\'', 'QL') |
+-------------------------+
| My'QL                   |
+-------------------------+

 There are several ways to include quote characters within a string:

    A “'” inside a string quoted with “'” may be written as “''”.

    A “"” inside a string quoted with “"” may be written as “""”.

    Precede the quote character by an escape character (“\”).

    A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a string quoted with “'” needs no special treatment.
All is well. I learn by answering your questions...
