Loading Data from MySQL

This section explains how to connect MySQL with Exasol and then load data.

To view details about data type mappings or to migrate data, see the MySQL to Exasol migration script in our GitHub repository.

Download Driver

Download the JDBC driver for MySQL from the MySQL Connectors page. In the Select Operating System dropdown menu, select Platform Independent.

Add JDBC Driver

To add a JDBC driver, you must create a configuration file called settings.cfg. Use the below settings to create the file, replacing the JAR entry with the name of the jar file you downloaded:

DRIVERNAME=MySQL
JAR=mysql-connector-java-8.0.30.jar
DRIVERMAIN=com.mysql.jdbc.Driver
PREFIX=jdbc:mysql:
NOSECURITY=YES
FETCHSIZE=100000
INSERTSIZE=-1

Follow the procedure described in Add JDBC Drivers to upload the settings.cfg configuration file and the JDBC driver jar file(s).

Run Statement

Run the following statement to create a connection.

The connection string and authentication details in the example must be replaced with your own values. The MySQL user must have enough privileges to create a connection.

CREATE OR REPLACE CONNECTION JDBC_MYSQL
    TO 'jdbc:mysql://192.168.99.100:3306/my_database' 
    USER 'user_name'
    IDENTIFIED BY 'my_password';

Run the following statement to test the connection.

select * from 
(
import from JDBC at JDBC_MYSQL
statement 'select ''Connection works'' from dual'
);

Load Data

You can use the IMPORT statement to load data using the connection you created above. IMPORT supports loading data from a table or a SQL statement.
