This table function can be used in queries to return the hourly credit usage for a single warehouse (or all the warehouses in your account) within a specified date range.

Note

This function returns credit usage within the last 6 months.

WAREHOUSE_LOAD_HISTORY

Syntax¶

WAREHOUSE_METERING_HISTORY(
      DATE_RANGE_START => <constant_expr>
      [ , DATE_RANGE_END => <constant_expr> ]
      [ , WAREHOUSE_NAME => '<string>' ] )
Copy

Arguments¶

Required:

DATE_RANGE_START => constant_expr

The starting date, within the last 6 months, for which warehouse usage is returned.

Optional:

DATE_RANGE_END => constant_expr

The ending date, within the last 6 months, for which warehouse usage is returned.

Default: CURRENT_DATE is used.

WAREHOUSE_NAME => 'string'

The name of the warehouse to retrieve credit usage for. Note that the warehouse name must be enclosed in single quotes. Also, if the warehouse name any spaces, mixed-case characters, or special characters, the name must be double-quoted within the single quotes (e.g. '"My Warehouse"' vs 'mywarehouse').

Default: All warehouses that ran during the specified date range.

Usage Notes¶

  • Returns results only for the ACCOUNTADMIN role or any role that has been explicitly granted the MONITOR USAGE global privilege.

  • When calling an Information Schema table function, the session must have an INFORMATION_SCHEMA schema in use or the function name must be fully-qualified. For more details, see Snowflake Information Schema.

  • The order and structure of the arguments depends on whether the argument keywords (e.g. DATE_RANGE_START) are included:

    • The keywords are not required if the arguments are specified in order.

    • If the argument keywords are included, the arguments can be specified in any order.
