SHOW INSPECT ERRORS

The SHOW INSPECT ERRORS displays errors recorded by an job, including background INSPECT jobs triggered by row count validation.

SHOW INSPECT ERRORS shows results for a single INSPECT job at a time; it does not aggregate results across jobs. To view errors from a specific job, including an inspect_job_id returned by , use SHOW INSPECT ERRORS FOR JOB {job_id}.

Required privileges

To run SHOW INSPECT ERRORS, the user must have:

table_name	The with an issue.
primary_key	The of the row involved in the issue, if applicable.

Error types

The INSPECT implementation reports the following error_type values:

Error type	Meaning
missing_secondary_index_entry	A row in the is missing a corresponding entry in a . If you see this error, .
dangling_secondary_index_entry	A entry exists, but the referenced row does not. If you see this error, .
internal_error	An error occurred while INSPECT was running its validation queries (for example, an ). The cause of this error type is usually not related to data validity. Investigate the underlying job error details and cluster logs to determine the cause before deciding whether to .
row_count_mismatch	The row count observed by INSPECT did not match the expected row count. This can occur in the post-import validation job triggered by . Use WITH DETAILS to compare the expected and actual counts.
duplicate_unique_value	INSPECT found a duplicate value in a supported uniqueness check. Use WITH DETAILS to see the index_name and remote_regions metadata for the duplicate.

Examples

Show the latest errors for a table

To see the errors found by the most recent INSPECT job, issue the following statement:

SHOW INSPECT ERRORS FOR TABLE movr.public.users;

Show errors for a specific inspection job

When you issue the , a NOTICE message is returned to the client showing the job ID, e.g.,

INSPECT TABLE movr.public.users AS OF SYSTEM TIME '-10s';

NOTICE:  waiting for INSPECT job to complete: 1141477013029322753
If the statement is canceled, the job will continue in the background.

To show errors for a job, issue the following statement:

SHOW INSPECT ERRORS FOR JOB 1141477013029322753;

If returns an inspect_job_id value for its post-import validation job, you can use that value with SHOW INSPECT ERRORS FOR JOB {inspect_job_id} as well.

If there are no errors associated with that job ID, the output is:

SHOW INSPECT ERRORS 0

Note that if you issue a job ID for a nonexistent job, you will see the same output as for a job with no errors:

SHOW INSPECT ERRORS FOR JOB 0;

SHOW INSPECT ERRORS 0

Show errors with details

SHOW INSPECT ERRORS FOR TABLE movr.public.users WITH DETAILS;
