Schema:: ACCOUNT_USAGE

LOAD_HISTORY View¶

This Account Usage view enables you to retrieve the history of data loaded into tables using the COPY INTO <table> command within the last 365 days (1 year). The view displays one row for each file loaded.

Note

This view does not return the history of data loaded using Snowpipe. For this historical information, query the COPY_HISTORY view instead.

Columns¶

Column Name	Data Type	Description
TABLE_ID	NUMBER	Internal/system-generated identifier for the target table
TABLE_NAME	TEXT	Name of target table
SCHEMA_ID	NUMBER	Internal/system-generated identifier for the schema of the target table
SCHEMA_NAME	TEXT	Schema of target table
CATALOG_ID	NUMBER	Internal/system-generated identifier for the database of the target table
CATALOG_NAME	TEXT	Database of target table
FILE_NAME	TEXT	Name of source file
LAST_LOAD_TIME	TIMESTAMP_LTZ	Date and time (in the UTC time zone) of the load record
STATUS	TEXT	Status: `LOADED`, `LOAD FAILED`, or `PARTIALLY LOADED`
ROW_COUNT	NUMBER	Number of rows loaded from the source file
ROW_PARSED	NUMBER	Number of rows parsed from the source file
FIRST_ERROR_MESSAGE	TEXT	First error of the source file
FIRST_ERROR_LINE_NUMBER	NUMBER	Line number of the first error
FIRST_ERROR_CHARACTER_POSITION	NUMBER	Position of the first error character
FIRST_ERROR_COL_NAME	TEXT	Column name of the first error
ERROR_COUNT	NUMBER	Number of error rows in the source file
ERROR_LIMIT	NUMBER	If the number of error reach this limit, then abort

Usage Notes¶

In most cases, latency for the view may be up to 90 minutes. The latency for a given table’s load history in the view may be up to 2 days if both of the following conditions are true:
- Fewer than 32 DML statements have been added to the given table since it was last updated in LOAD_HISTORY.
- Fewer than 100 rows have been added to the given table since it was last updated in LOAD_HISTORY.

The view only includes COPY INTO commands that executed to completion, with or without errors. No record is added if the transaction is rolled back, for example, or if the ON_ERROR = ABORT_STATEMENT copy option is included in the COPY INTO <table> statement and a detected error in a data file aborts the load operation.
When including a WHERE clause that references the LAST_LOAD_TIME column, you can specify any day of the week. For example, April 1, 2016 was a Friday; however, specifying Sunday instead does not affect the query results:
```
WHERE last_load_time > 'Sun, 01 Apr 2016 16:00:00 -0800'
```
Copy

After the replication of load history, the LOAD_HISTORY Account Usage view shows the history only after the latest truncate operation on the target table. This is different from the view without replication, which shows a complete data loading history.

Examples¶

Retrieve records for the 10 most recent COPY INTO commands executed:

SELECT file_name, last_load_time FROM snowflake.account_usage.load_history
  ORDER BY last_load_time DESC
  LIMIT 10;
