Support for MemSQL - and Advanced View for transparency of connection details

[SeanAdams]

MemSQL is a very popular high-velocity; high scalability database which is often used for analytics: https://portal.memsql.com/

However, when attempting to make a connection to MemSQL, Alteryx throws the error "Get Table List Error: Error opening "SHOW VARIABLES LIKE 'aurora_version'": No Columns Returned."

From discussions with the support team at Alteryx - it appears that this is due to Alteryx presuming that the database is a MySQL database (because MemSQL also uses the MariaDB ODBC driver) and then sending a followup query to identify system version before making a connection - however MemSQL does not support this value so the connection fails.

Request:

- Please can we add the ability to connect to MemSQL without this error (i.e. trap this error and identify the DB version)

- Please can we give an advanced view to Alteryx users so that they can see this additional traffic and change this where needed?

          NOTE: By providing an advanced view - users can understand and diagnose / fix behaviours that Alteryx assumes by default, but which are not always relevant or useful.   An example of this is that on MS SQL Alteryx tries to open a cursor on columnstore tables by default and you have to use a workaround - please can you give us the ability to see and change these under-the-covers behaviours that are presumed by default.

- It may be useful to the Alteryx corporation to reach out to MemSQL and add Alteryx to the list of applications that can be used with MemSQL:

To replicate:

- Fire up a MemSQL cluster (easiest is to get a trial cluster using the link above, or use an internal DB)

- Connect to this DB using the MariaDB ODBC connector (as recommended by MemSQL)

- Test this connection works with an ODBC compliant app like Tableau; Excel; etc

- Then attempt to connect using Alteryx  - see screenshot below.
