System functions

Snowflake provides the following types of system functions:

  • Control functions that allow you to execute actions in the system (for example, aborting a query).
  • Information functions that return information about the system (for example, calculating the clustering depth of a table).
  • Information functions that return information about queries (for example, information about EXPLAIN plans).

Many of these system functions have the prefix SYSTEM$ (for example, SYSTEM$TYPEOF). For the system functions that use this prefix, you must specify the prefix when calling the function. For example:

SELECT SYSTEM$TYPEOF('a');
