# 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 ) ....
