Don't know how to query for sequences on MariaDB

Environment

Liquibase Version: 4.0.0

Liquibase Integration & Version: CLI

Liquibase Extension(s) & Version: NO

Database Vendor & Version: docker official mariadb (image-id: 22851c7fe916) mariadb --version: mariadb Ver 15.1 Distrib 10.5.4-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2 jdbc driver: org.mariadb.jdbc:mariadb-java-client:2.6.1

Operating System Type & Version: Ubuntu 20.04 LTS (Focal Fossa)

Description

Liquibase 4.0.0 is able to write sequences into the mariadb instance, but it can’t query the sequences when it is attempting to loadUpdateData into the table.

The issue is related to the class liquibase.snapshot.jvmSequenceSnapshotGenerator, in the method getSelectSequenceSql

MariaDB query isn’t implemented there. It should add something like this:

} else if (database instanceof MariaDBDatabase) {
  return "SELECT TABLE_NAME AS SEQUENCE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='SEQUENCE' AND TABLE_SCHEMA='" + schema.getName() + "'"
} else {
  throw new UnexpectedLiquibaseException("Don't know how to query for sequences on " + database);
}

Steps To Reproduce

test_table.csv

id_test, test_text
1, text 1
2, text 2
3, text 3

$ docker run -p 3306:3306 -e MYSQL_ROOT_PASSWORD=your_password mariadb

$ java -jar liquibase.jar --changeLogFile changelog-test.yml --url "jdbc:mariadb://localhost/mysql" --username root --password "your_password" update

Actual Behavior

Error message:

Unexpected error running Liquibase: Migration failed for change set changelog-test.yml::test-dml::test:
     Reason: liquibase.exception.UnexpectedLiquibaseException: Don't know how to query for sequences on root @ jdbc:mariadb://localhost/mysql (Default Schema: mysql)
For more information, please use the --logLevel flag

Expected/Desired Behavior

Conclude the loadUpdateData without issues.

Isn’t this fixed by #1024?

It’s related. But the pushed code isn’t part of the version 4.0.0. I think we should try to bring these changes to v4 and test them.

Looks like it got fixed for liquibase 4.15. Try upgrading your liquibase version to latest, if this doesnt fix your issue, please try to re-open the issue and we will look into it again. Thanks!
