SQL Selector Operator Errors
If Teradata Database encounters any errors while the SQL Selector operator is retrieving LOB, JSON, or XML data, the job will be terminated with error messages.
If any errors occur on the client side (for example, if there is an I/O error while writing LOB, JSON or XML data to a file), the SQL Selector operator will issue an explanatory error message and terminate the job.
When a client-side failure causes the SQL Selector operator to terminate the job, the temporary work files that it creates to transport LOB, JSON, or XML data from the source table to the target may not get deleted.
