Examples of Aggregate Functions

Below are several examples of SQL aggregate functions. You can use these with a GROUP BY clause to aggregate rows based on the specified GROUP BY criterion. This can be a reporting tool.

COUNT

Returns the number of rows matching the query criteria.

SELECT COUNT(*) FROM projects WHERE Archived = 'true'

COUNT(DISTINCT)

Returns the number of distinct, non-null field values matching the query criteria.

SELECT COUNT(DISTINCT Id) AS DistinctValues FROM projects WHERE Archived = 'true'

AVG

Returns the average of the column values.

SELECT WorkspaceId, AVG(AnnualRevenue) FROM projects WHERE Archived = 'true' GROUP BY WorkspaceId

MIN

Returns the minimum column value.

SELECT MIN(AnnualRevenue), WorkspaceId FROM projects WHERE Archived = 'true' GROUP BY WorkspaceId

MAX

Returns the maximum column value.

SELECT WorkspaceId, MAX(AnnualRevenue) FROM projects WHERE Archived = 'true' GROUP BY WorkspaceId

SUM

Returns the total sum of the column values.

SELECT SUM(AnnualRevenue) FROM projects WHERE Archived = 'true'
