System Functions (System Information)



## Arguments¶

external_table_name

External table for which you want to retrieve the current automatic refresh status.

## Usage Notes¶

• This function only returns results for the external table owner (i.e. the role that has the OWNERSHIP privilege on the external table).

• external_table_name is a string so it must be enclosed in single quotes:

• Note that the entire name must be enclosed in single quotes, including the database and schema (if the name is fully-qualified), i.e. '<db>.<schema>.<external_table_name>'.

• If the external table name is case-sensitive or includes any special characters or spaces, double quotes are required to process the case/characters. The double quotes must be enclosed within the single quotes, i.e. '"<pipe_name>"'.

## Output¶

The function returns a JSON object containing the following name/value pairs (if applicable to the current pipe status):

Where:

executionState

Current execution state of the pipe. The value could be any one of the following:

• RUNNING (i.e. everything is normal; Snowflake may or may not be actively processing event messages for this pipe)

• STOPPED_CLONED (i.e. the pipe is contained by a database or schema clone)

• STOPPED_FEATURE_DISABLED

• STOPPED_STAGE_DROPPED

• STOPPED_FILE_FORMAT_DROPPED

• STOPPED_NOTIFICATION_INTEGRATION_DROPPED

• STOPPED_MISSING_PIPE

• STOPPED_MISSING_TABLE (the target table defined in the pipe definition was dropped)

• STALLED_COMPILATION_ERROR

• STALLED_INITIALIZATION_ERROR

• STALLED_EXECUTION_ERROR

• STALLED_INTERNAL_ERROR

• PAUSED

• PAUSED_BY_SNOWFLAKE_ADMIN

• PAUSED_BY_ACCOUNT_ADMIN

oldestPendingFilePath

Path to the oldest data file currently queued for a metadata refresh operation. The timestamp when the file was added to the queue is returned in the oldestFileTimestamp property.

oldestFileTimestamp

Earliest timestamp among data files currently queued for a metadata refresh operation (if applicable), where the timestamp is set when the file is added to the queue.

pendingFileCount

Number of files currently being processed by the pipe. This value decreases as the external table metadata is refreshed. When this value is 0, either there are no metadata refreshes queued for this pipe.

lastPipeFaultTimestamp

Timestamp when an internal Snowflake process error was last detected.

notificationChannelName

Amazon SQS queue or Microsoft Azure storage queue associated with the pipe.

numOutstandingMessagesOnChannel

Number of messages in the queue that have been queued but not received yet.

lastReceivedMessageTimestamp

Timestamp of the last message received from the queue.

lastForwardedMessageTimestamp

Timestamp of the last applicable event message with a matching path/prefix that was forwarded to the pipe.

channelErrorMessage

Error message produced when attempting to read messages from the associated cloud messaging service queue.

lastErrorRecordTimestamp

Timestamp of last channel error message (i.e. error message reported in the channelErrorMessage value).

error

Error message produced when the pipe was last compiled for execution (if applicable); often caused by problems accessing the necessary objects (i.e. table, stage, file format) due to permission problems or dropped objects.

fault

Most recent internal Snowflake process error (if applicable). Used primarily by Snowflake for debugging purposes.

lastPulledFromChannelTimestamp

Timestamp when Snowpipe last pulled event notifications for the pipe from the cloud messaging service queue.

lastForwardedFilePath

Path of the data file identified in the last applicable event message that was forwarded to the pipe.

## Examples¶

Retrieve the automatic refresh status for an external table with a case-insensitive name:

SELECT SYSTEM$EXTERNAL_TABLE_PIPE_STATUS('mydb.myschema.exttable'); +---------------------------------------------------------------+ | SYSTEM$EXTERNAL_TABLE_PIPE_STATUS('MYDB.MYSCHEMA.EXTTABLE')   |
|---------------------------------------------------------------|
| {"executionState":"RUNNING","pendingFileCount":0}             |
+---------------------------------------------------------------+


Retrieve the status for a pipe with a case-sensitive name:

SELECT SYSTEM$EXTERNAL_TABLE_PIPE_STATUS('mydb.myschema."extTable"'); +---------------------------------------------------------------+ | SYSTEM$EXTERNAL_TABLE_PIPE_STATUS('MYDB.MYSCHEMA."extTable"') |
|---------------------------------------------------------------|
| {"executionState":"RUNNING","pendingFileCount":0}             |
+---------------------------------------------------------------+
