    • Dates
    • Strings

  • When the function finds no rows to count, it returns a blank.

  • Blank values are skipped. TRUE/FALSE values are not supported.

  • If you want to evaluate a column of TRUE/FALSE values, use the COUNTA function.

  • This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

  • For best practices when using COUNT, see Use COUNTROWS instead of COUNT.

Example

The following example shows how to count the number of values in the column, ShipDate.
