ACCESS LOCK allows you to read the data from a table that may have been locked for the READ or WRITE.

Use the tdMigrateLOCKoption configuration parameter to configure migration of query containing the LOCK keyword. If tdMigrateLOCKOption is set to false, the tool will skip migration of the query and will log a message.
