Steps to reproduce:

1. Code: https://github.com/zabbix/zabbix/blob/release/7.0/ui/include/classes/db/MysqlDbBackend.php
2. Line 175
3. If ANSI Mode is enabled (to make any query more compliant), this query will break the Zabbix Front End.

Result:

Expected:

I tried searching if there's anywhere else with a non-compliant SQL Query, but it seems it's only this line of code.

To make it compliant, any `"` (double quotes) in SQL queries must be changed to `'` (single quote). And I'm pretty sure this is the only non-compliant query.

Affected versions: 6.0, 6.4, 7.0
