Mysql connector - MultipleActiveResultSets issue

Question

First off, I have spent hours looking for a fix - maybe I just need another pair of eyes on this problem.

I'm currently coding a c# application for myself(Personal use). Im running the latest MySQL connector library from mysql.com

My connection string is

public string SQLConnection = "Server=localhost;Database=data;Uid=root;Pwd=ascent;charset=utf8;MultipleActiveResultSets=True;";

My issue is regarding MultipleActiveResultSets=True; . When this is included in my SQLConnection string the MySQL library is unable to connect. View the pic below to view my findings

When MultipleActiveResultSets=True; is removed from the connection string, I get this result

I get a successful connection.

The reason for MultipleActiveResultSets is because I'm using 2 MySqlDataReader at the same time - This however can't be changed.

If anyone knows why this is failing, then please suggest your fix.

My local MySQL server version: 5.6.17

Solution 1

I assume MySql connector doesn't support MARS (Multiple active result sets). In such case you cannot use it at more than one place at the same time.

Solution 2

The problem is not solved but I have found a work around.

I removed MultipleActiveResultSets=True; from the connection string. I then created a list where I saved the data from MySqlDataReader, I then closed the reader and reopen a new one which then I got the rest of the data from the database. Then simply merged the results together in the list.

So yeah, a temp fix.

If someone knows the proper fix then please comment, otherwise I will be using my temp fix.

Thanks guys.
