LOAD_HISTORY View

This Information Schema view enables you to retrieve the history of data loaded into tables using the COPY INTO <table> command. The view displays one row for each file loaded.

Note

The view only includes COPY INTO commands that executed to completion, with or without errors.

Usage Notes

  • Snowflake retains historical data for COPY INTO commands executed within the previous 14 days only.

  • The historical data for COPY INTO commands is removed from the system when a table is dropped.

  • This view returns an upper limit of 10,000 rows. To avoid this limitation, use the COPY_HISTORY function (Information Schema) or view (Account Usage).

  • 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'
    

Examples

Retrieve the history of data loaded into the MYDB.PUBLIC.MYTABLE table since April 1, 2016, assuming that April 1 occurred within the previous 14 days:

USE DATABASE mydb;

SELECT * FROM information_schema.load_history
  WHERE schema_name=current_schema() AND
  table_name='MYTABLE' AND
  last_load_time > 'Fri, 01 Apr 2016 16:00:00 -0800';

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

USE DATABASE mydb;

SELECT * FROM information_schema.load_history
  ORDER BY last_load_time DESC
  LIMIT 10;
