If auto-commit is false, then an explicit commit or rollback is required to close a transaction. If auto-commit is set to true, then a statement that requires a transaction is executed within a transaction implicitly. The auto-commit property determines whether statement should be implicitly wrapped within a transaction or not. If true, Snowflake will automatically abort queries when it detects that the client has disappeared. Use the following command to show all the parameters provided by snowflake −įollowing are the few details which can be viewed by just running the query "SHOW PARAMETERS " Sr.No Use the following command to see all the columns − Results provide timestamp, username, how login has done either using password or SSO, errors during login etc. Select * from table(test_db.information_schema.login_history()) Use the following query to find the login history of a database − Select * from table(result_scan(last_query_id())) JOIN snowflake_sample_data.tpch_sf1.nation SELECT * FROM snowflake_sample_data.tpch_sf1.region To check variables, run following queries in sequence − Use the following query to check stages and file format created in Snowflake − SELECT * FROM TABLE (INFORMATION_SCHEMA.DATABASE_STORAGE_USAGE_HISTORY Use the following query to display the usage of last 10 days. This query will display only the first 10 rows. Use the following query to bring limited data in Select statement − In this chapter, we will some sample useful queries in Snowflake and their outputs.
