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 SettledBatchList WHERE IncludeStatistics = 'True'

COUNT(DISTINCT)

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

SELECT COUNT(DISTINCT TotalCharge) AS DistinctValues FROM SettledBatchList WHERE IncludeStatistics = 'True'

AVG

Returns the average of the column values.

SELECT Product, AVG(AnnualRevenue) FROM SettledBatchList WHERE IncludeStatistics = 'True' GROUP BY Product

MIN

Returns the minimum column value.

SELECT MIN(AnnualRevenue), Product FROM SettledBatchList WHERE IncludeStatistics = 'True' GROUP BY Product

MAX

Returns the maximum column value.

SELECT Product, MAX(AnnualRevenue) FROM SettledBatchList WHERE IncludeStatistics = 'True' GROUP BY Product

SUM

Returns the total sum of the column values.

SELECT SUM(AnnualRevenue) FROM SettledBatchList WHERE IncludeStatistics = 'True'

COUNT
