MySQL Connections
You can create connections to 1 or more MySQL databases from Alteryx Analytics Cloud (AAC). For more information on MySQL, see https://www.mysql.com/.
Tip
You can create connections to databases of this type that are managed by your enterprise or are hosted in cloud infrastructure. The required configuration is the same. The cloud-based version is labeled on Amazon RDS. In the Create Connection dialog, you can search for that term.
If you are connecting AAC to any relational source of data, such as Redshift or Oracle, you must add the Alteryx Service to your allowlist for those resources. See Allowlist Platform Service.
Supported Versions: 5.7 and 8.0 Community
Read: Supported
Write: Supported
Configure
To create this connection:
In the Import Data page, click the Plus sign. Then, select the Relational tab. Click the MySQL card.
You can also create connections through the Connections page.
See Connections Page.
Modify the following properties as needed:
Property | Description |
---|---|
Host | Enter your fully qualified hostname. Example: mysql-server.example.net |
Port | Set this value to |
Connect String Options | Insert any additional connection parameters, if needed. See below. |
User Name | Username to use to connect to the database. |
Password | Password associated with the above username. |
Test Connection | After you have defined the connection credentials type, credentials, and connection string, you can validate those credentials. |
Advanced options: Default Column Data Type Inference | Set to |
Advanced options: Enable SSH Tunneling | If available, the SSH tunneling options allow you to configure SSH tunneling authentication between AAC and your database. Note SSH tunneling is available on a per-connection basis. It may not be available for all connections. For more information, see Configure SSH Tunnel Connectivity. |
Connection Name | Display name of the connection |
Connection Description | Description of the connection, which appears in the application. |
Connection URL
The properties that you provide are inserted into the following URL, which connects AAC to the connection:
jdbc:mysql://<host>:<port>/<database><connect-string-options>
Connect string options
The connect string options are optional. If you are passing additional properties and values to complete the connection, the connect string options must be structured in the following manner:
&<prop1>=<val1>&<prop2>=<val2>...
where:
<prop>
: the name of the property<val>
: the value for the property
delimiters:
&
: all additional property names must be prefixed with an ampersand (&
).=
: property names and values must be separated with an equal sign (=
).
Default connect string options
The following connect string options are specified by default.
Note
These options should not be overridden or modified.
The following connect string option requires the driver to use cursor-based fetching to retrieve rows.
useCursorFetch=true;
Enable TLS (SSL)
You can insert the following connection string option to enable secure (TLS) connectivity with the MySQL server. Please note the TLS version numbers in the string listed below:
&enabledTLSProtocols=TLSv1,TLSv1.1,TLSv1.2
Set time zone
When data is imported from MySQL, the connector performs time zone adjustments to imported Datetime values.
Tip
By default, the MySQL driver adjusts the imported data to be represented in the time zone into which it is being read. If you are located in GMT -08:00, all data is rendered that your AAC user reads into the application through the MySQL connector is adjusted to this time zone.
These adjustments are performed in either of the following cases:
The MySQL server is configured with a canonical time zone that is recognizable by Java (for example, Europe/Paris, Etc/GMT-5, UTC, etc.).
The server's time zone is overridden by setting the Connector/J connection property serverTimezone.
In the latter case, you can specify the override time zone to apply as part of the connection string:
&serverTimezone=Europe/Paris
The following value sets the time zone of imported data to be UTC:
&serverTimezone=UTC
For more information on this behavior, see https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-other-changes.html.

Troubleshooting
Error message | Description |
---|---|
1042 - ER_BAD_HOST_ERROR | Unable to connect to host. Please verify the host and port values. |
1045 - ER_ACCESS_DENIED_ERROR | Credentials failed to connect. Please verify your credentials. Tip Click the Test Connection button to verify that your credentials are working properly. |
Error: zero date value prohibited | Set the following option in the connect string options: zeroDateTimeBehavior=convertToNull |
Prepared statement needs to be re-prepared. | Database Cursor is not compatible with PREPARED statements in MySQL. The fix is to set the following in the Connect String Options: useCursorFetch=false |
SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate) | SSL ciphers need to be enabled. For more information, see "Enable TLS (SSL)" above. |
