What Debezium connector do you use and what version?

debezium-connector-jdbc-2.7.0.Alpha1.jar

What is the connector configuration?

{
  "name": "jdbc-upsert-connector",
  "config": {
    "connector.class": "io.debezium.connector.jdbc.JdbcSinkConnector",
    "connection.password": "[my-password]",
    "tasks.max": "1",
    "connection.username": "[my-username]",
    "delete.enabled": "true",
    "auto.create": "false",
    "auto.evolve": "true",
    "driver.class": "org.mariadb.jdbc.Driver",
    "connection.url": "jdbc:mariadb://[host]:[port]/[db]",
    "primary.key.mode": "record_key",  
    "topics": "debezium-server.public.User",
    "schema.evolution": "basic",
    "insert.mode": "upsert",
    "transforms.unwrap.drop.tombstones": "false"

  }}

What is the captured database version and mode of depoyment?

(E.g. on-premises, with a specific cloud provider, etc.)

MariaDB 10.6.17 deployed by docker in WSL

What behaviour do you expect?

when data is updated, I want the sql statement to be like this.

ex)

INSERT INTO `debezium-server_public_User` (id, email, name) VALUES (1, 'test1@test.com', 'name') ON DUPLICATE KEY UPDATE email=VALUES(email),name=VALUES(name)

What behaviour do you see?

HOWEVER, due to conditional statement in the source code (MySQLDatabaseDialect.java)

// code placeholder
if (getDatabaseVersion().isSameOrAfter(8, 0, 20)) {
    // MySQL 8.0.20 deprecated the use of "VALUES()" in exchange for table aliases
    builder.append("AS new ON DUPLICATE KEY UPDATE ");
    builder.appendList(",", updateColumnNames, (name) -> {
    final String columnName = columnNameFromField(name, record);
    return columnName + "=new." + columnName;
    });
}
else {
   builder.append("ON DUPLICATE KEY UPDATE ");
   builder.appendList(",", updateColumnNames, (name) -> {
       final String columnName = columnNameFromField(name, record);
       return columnName + "=VALUES(" + columnName + ")";
   });
}

It's using the statement using "AS new" and it's not supported by MariaDB yet.

Do you see the same behaviour using the latest relesead Debezium version?

(Ideally, also verify with latest Alpha/Beta/CR version)

<Your answer>

Yes( Alpha)

Do you have the connector logs, ideally from start till finish?

(You might be asked later to provide DEBUG/TRACE level log)

Implementation ideas (optional)

For temporary use, can the hibernate recognize if it's mariadb or mysql, and define its version separately?
