SQL Server RANGE Function
Updated 2023-10-24 13:42:47.427000
Description
Use the aggregate function RANGE to calculate the difference between the minimum and maximum values in a dataset.
Syntax
SELECT [westclintech].[wct].[RANGE] (
<@x, float,>)
Arguments
@x
the input values for the function. @x is an expression of type float or of a type that can be implicitly converted to float.
Return Type
float
Remarks
RANGE is an aggregate function and follows the same conventions as all other aggregate functions in SQL Server.
If there is only one value in the dataset, then the range is zero.

GROUP BY city

This produces the following result.
| city | Range |

In this example we calculate range for a variety of data groupings, including one NULL value and a GROUP that only contains one member.
