Creating a Table in the Database Before Running the Job

  • When a JDBC table is used as the sink table, you need to create an empty table for receiving data in the corresponding database (such as MySQL) before running the job.
  • When a JDBC table is used as the dimension table, you need to create a dimension table in the corresponding database (such as MySQL) before running the job.
