System Functions

Snowflake provides the following types of system functions:

  • Control functions that allow you to execute actions in the system (e.g. aborting a query).

  • Information functions that return information about the system (e.g. calculating the clustering depth of a table).

  • Information functions that return information about queries (e.g. information about EXPLAIN plans).

Regardless of their type, all system functions are called using the following syntax: ... SYSTEM$function_name ( arguments ) ....
