Describes the columns in the result of a query.
Snowflake persists the result of a query for a period of time, after which the result is purged. The query can be from the current session or any of your other sessions, including past sessions, as long as the limited period has not elapsed. This period is not adjustable. For more details, see Using Persisted Query Results.
DESCRIBE can be abbreviated to DESC.
LAST_QUERY_ID (Context function) , RESULT_SCAN (Table function)
DESC[RIBE] RESULT { '<query_id>' | LAST_QUERY_ID() }
Copy
Parameters¶query_id or LAST_QUERY_ID()
Specifies either the ID for a query you executed (within the last 24 hours in any session) or the LAST_QUERY_ID function, which returns the ID for a query within your current session.
To retrieve the ID for a specific query:
Locate the query ID in the web interface. The History page lists the ID along with each query; however, note that you can only use this function for queries you have executed.
Execute the QUERY_HISTORY , QUERY_HISTORY_BY_* table function, which returns a list of queries and their IDs; however, note that you can only use this function for queries you have executed.
If the query was executed in the current session, execute the LAST_QUERY_ID function. For example:
SELECT LAST_QUERY_ID(-2);Copy
Note that this is equivalent to using LAST_QUERY_ID() as the input for DESC RESULT.
To post-process the output of this command, you can use the pipe operator (->>) or the RESULT_SCAN function. Both constructs treat the output as a result set that you can query.
The output column names for this command are generated in lowercase. If you consume a result set from this command with the pipe operator or the RESULT_SCAN function, use double-quoted identifiers for the column names in the query to ensure that they match the column names in the output that was scanned. For example, if the name of an output column is type, then specify "type" for the identifier.
Describe the columns in the result of the specified query from any of your sessions (within the previous 24 hours):
DESC RESULT 'f2f07bdb-6a08-4689-9ad8-a1ba968a44b6';Copy
Describe the columns in the results from your most recent query in the current session:
