MariaDB Connector

Version 2

 

Intro

MariaDB is a community-developed fork of the MySQL relational database management system. Use Domo's MariaDB connector to take advantage of MariaDB's speed and other improvements to MySQL's database system when connecting to either MariaDB or MySQL databases. You can easily and securely access your data in minutes to get more visibility. To learn more about MariaDB, visit https://mariadb.com/docs/.

You connect to your MariaDB data in the Data Center. This topic discusses the fields and menus that are specific to the MariaDB connector user interface. General information for adding DataSets, setting update schedules, and editing DataSet information is discussed in Adding a DataSet Using a Data Connector.

Prerequisites

To connect to your MariaDB database and create a DataSet, you must have the following:

  • The username and password you use to log into your MariaDB account

  • The host name for the database

  • The port number for the database

  • The database or schema name

You can also include the URL where your SSL CA Certificate is located, though this is optional.

Before you can connect to a MariaDB database, you must also white list a number of IP addresses on your database server on the port you want to connect to. For the full list of IP addresses, see Whitelisting IP Addresses for Connectors.

Connecting to Your MariaDB Database

This section enumerates the options in the Credentials and Details panes in the MariaDB Connector page. The components of the other panes in this page, Scheduling and Name & Describe Your DataSet, are universal across most connector types and are discussed in greater length in Adding a DataSet Using a Data Connector.

Credentials Pane

This pane contains fields for entering credentials to connect to your MariaDB database. The following table describes what is needed for each field:  

Field

Description

Host Enter the hostname or IP address of your database server. Example: db.company.com
Port Enter the port number for your database.
Database Name Enter your database name.
Username Enter your MariaDB username.
Password Enter your MariaDB password.
CA Certificate Paste the text for your CA certificate or enter the URL where your certificate is located. This is optional.

Once you have entered valid MariaDB credentials, you can use the same account any time you go to create a new MariaDB DataSet. You can manage connector accounts in the Accounts tab in the Data Center. For more information about this tab, see Managing User Accounts for Connectors.

Details Pane

In this pane you create an SQL query to pull data from your database. The Query parameter is required. The other three parameters are here to help you construct this query if you choose.

Menu

Description

Query Type Select the desired query type—either with or without a parameter
Query

Enter the Structured Query Language (SQL) query to select the data you want. Example:

select * from Employee

You can use the Query Helper parameter to help you write a usable SQL query. To use the Query Helper, do the following:

  1. Select your database table and table columns in the appropriate menus.

  2. Copy the SQL statement that appears in the Query Helper field.

  3. Paste the copied SQL statement into the Query field.

Query Parameter

Enter the query parameter value. This is the initial value for the query parameter. You can use this option to retrieve new data since the last run. The last run date is optional.

Example: If you entered the following query in the Query field...

select * from test.lastValue where id <= !{lastvalue:id}! order by id desc

...and then entered the following for the Query Parameter...

!{lastvalue:id}!=3

...then the first run would return 3 rows, and all subsequent runs would return 1 row, and the results would be ordered from largest to smallest. 

Similarly, if you entered the following in the Query field...

select * from test.lastValue where time > !{lastrundate:time}!

...and then entered the following for the Query Parameter...

!{lastrundate:time}!=01/01/1990

...then the first run would return 5 rows and all subsequent runs would return 0 rows.

TinyInt Values Treated as Boolean Values Select Yes if you want TinyInt values to be treated as Boolean.
Cast Boolean Values To... Select whether Boolean values will be cast to integers or strings.
Database Tables (Optional) Select the database table you want to import into Domo. 
Table Columns (Optional) Select the table columns you want to import into Domo.
Query Helper (Optional) Copy and paste the SQL statement in this field into the Query field. For more information, see Query, above.
