Troubleshooting SQLines Data for MySQL to Oracle Migration

There are two main sources that can help you troubleshoot SQLines Data:

  • sqldata.log file

sqldata.log file contains the detailed information about MySQL to Oracle migration process.

By default, sqldata.log file is located in the current working directory. You can use -log command line option to change its location and file name.

  • sqldata_ddl.sql file

sqldata_ddl.sql file contains information about all DDL statements executed in MySQL during migration.

In this file you can see the full SQL statements, the execution result (success or failure) and the execution time. In case of an error, you can find the error message returned by MySQL.

By default, sqldata_ddl.sql file is located in the current working directory. You can use -out command line option to change its location.

  • sqldata_failed.sql file

If there are any failed SQL statements, you can find them in sqldata_failed.sql file.

Duplicate entry for key 'PRIMARY'

When creating a primary key or unique constraint after loading the data, you can get a “Duplicate entry for key 'PRIMARY'” error. See this article for details.
