|---|---|
| APPROXIMATEDISTINCTCOUNT | Counts the approximate number of distinct values in a column. Currently this function is only available on a DirectQuery table from Azure SQL or Azure SQL Data Warehouse. |
| AVERAGE | Returns the average (arithmetic mean) of all the numbers in a column. |
| AVERAGEA | Returns the average (arithmetic mean) of the values in a column. Handles text and non-numeric values. |
| AVERAGEX | Calculates the average (arithmetic mean) of a set of expressions evaluated over a table. |
| COUNT | Counts the number of rows in the table where the specified column has a non-blank value. |
| COUNTA | Counts the number of values in a column. |
| COUNTAX | Counts the number of values which result from evaluating an expression for each row of a table. |
| COUNTBLANK | Counts the number of blanks in a column. |
| COUNTROWS | Counts the number of rows in a table. |

| MINA | Returns the smallest value in a column. Does not ignore logical values and text. |
| MINX | Returns the smallest value that results from evaluating an expression for each row of a table. Strings are compared according to alphabetical order. |
| PRODUCT | Returns the product of given column reference. |
| PRODUCTX | Returns the product of an expression values in a table. |
| SUM | Adds all the numbers in a column. |
