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.

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'
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;
