PowerBI import data with text filter raises SQL syntax error (Reproducible!)

Hi,
I found a bug of MariaDB Connector for PowerBI.

I reported about it to PowerBI community, but they couldn't help it since they (MS) don't have the ownership of MariaDB Connector.

https://community.powerbi.com/t5/Issues/Import-data-from-MariaDB-with-text-filter-raises-SQL-syntax/idc-p/1818877#M66248

The following is my original post, so please refer to it and fix the problem.

Best,

Hi,
I'm using PowerBI (version 2.92.706.0, 64-bit) and MariaDB as data source. I downloaded ODBC driver versions 3.1.11 from following link:
https://mariadb.com/downloads/?showall=1&tab=connectors&group=mariadbconnectors&product=ODBC%20conne...

Connection & Simple import job worked well. But when I add text filtering (equality check) in Power Query Editor, it raises SQL syntax error like this:

[ma-3.1.11][10.3.25-MariaDB-0ubuntu0.20.04.1-log]You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'LONG VARCHAR) = ? and `PARTNERS` is not null' at line 11

PARTERS is the column name which I add filter to.

It's very easy to reproduce the problem. In MariaDB just create a table like this:

create table test (name varchar(256), score int(11));

then, insert two rows:

insert into test values ('john', 90);
insert into test values ('nick', 80);

To get data from MariaDB in PowerBI, import 'test' table then click 'transform data'. In resulting Power Query Editor, add text filter for name 'nick'. Then close & load.

That's all, I hope you could reproduce the problem, and fix it SOON!
(In my opnion, it's related with length of VARCHAR. VARCHAR(10) column did not raised the problem)

Best.
