Liquibase MySQL driver can be mastered with a little help from our experts.

At Bobcares, we offer solutions for every query, big and small, as a part of our MySQL Support Service.

Let’s take a look at how our Support Team is ready to help customers with Liquibase MySQL driver.

How to use Liquibase MySQL driver

Our Support Techs are here with this handy guide to help use Liquibase and MySQL. Before we dive in, here are the prerequisites to using Liquibase and MySQL:

• Install the latest version of Liquibase from this link.
• Create a Liquibase project folder to store Liquibase files.
• Create a new liquibase.properties file or we can also use an existing liquibase.properties file from the installation package.

In order to use Liquibase and MySQL, we also need to have the JDBC file. Our Support Team recommends:

1. First, download the MySQL JDBS Driver.
2. Next, move the mysql-connector-java-version.jar file to the liquibase/lib directory.

Furthermore, if we are using Maven, we have to download the MySQL driver jar file as well. Then we have to place the driver in a location with access by the Maven build. After that, we have to configure the Maven pom.xml file so that it uses the local copy of the driver jar file.

How to test the connection

1. First, check the status by running:
   • • The net start MySQL or services.msc command for Windows.
     • The sudo service mysql status command for Linux.
2. Next, add the database URL to the liquibase.properties file.
3. After that, create a text file called changelog in the project directory and also add a changeset.
4. Then, run the status command to check if the connection is successful.
5. We can run the first update with the update command to make changes to the database. We can also run the updateSQL command if we want to analyze SQL before running the update command.

After the first update, our database contains the table we added along with the DATABASECHANGELOGLOCK and the DATABASECHANGELOG tables. Let’s have a look at what these tables offer us:

• DATABASECHANGELOGLOCK table: This table is put to use internally by Liquibase in order to manage access to the DATABASECHANGELOG table. Furthermore, it ensures only a single instance of Liquibase gets to update the database at a time, whether it’s updating, creating, or deleting changes.
• DATABASECHANGELOG table: This table contains information on all channelsets deployed. Moreover, when we deploy, the changesets are compared with DATABASECHANGELOG tracking table, and only new changesets already not in DATABASECHANGELOG will be deployed.
