    Details

      Description

      org.mariadb.jdbc.internal.com.read.resultset.SelectResultSet#getMetadata always returns a MariaDbResultSetMetaData which is not updatable, which results in isReadOnly(int column) to always return true

      JDBC state that https://docs.oracle.com/en/java/javase/11/docs/api/java.sql/java/sql/ResultSetMetaData.html#isReadOnly(int) Indicates whether the designated column is definitely not writable. Driver indicate that resultset not an updatable resultset and all its columns are readOnly.

      Instead only effectively readOnly-columns should return true
