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

SELECT COUNT(*) FROM GoalHeadings WHERE Name <> 'MyAccount'

COUNT(DISTINCT)

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

SELECT COUNT(DISTINCT GoalHeadingId) AS DistinctValues FROM GoalHeadings WHERE Name <> 'MyAccount'

AVG

Returns the average of the column values.

SELECT GoalHeadingId, AVG(AnnualRevenue) FROM GoalHeadings WHERE Name <> 'MyAccount' GROUP BY GoalHeadingId

MIN

Returns the minimum column value.

SELECT MIN(AnnualRevenue), GoalHeadingId FROM GoalHeadings WHERE Name <> 'MyAccount' GROUP BY GoalHeadingId

MAX

Returns the maximum column value.

SELECT GoalHeadingId, MAX(AnnualRevenue) FROM GoalHeadings WHERE Name <> 'MyAccount' GROUP BY GoalHeadingId

SUM

Returns the total sum of the column values.

SELECT SUM(AnnualRevenue) FROM GoalHeadings WHERE Name = 'MyAccount'
