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 DataModels WHERE Id = 'SampleDataset'

COUNT(DISTINCT)

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

SELECT COUNT(DISTINCT Name) AS DistinctValues FROM DataModels WHERE Id = 'SampleDataset'

AVG

Returns the average of the column values.

SELECT Owner, AVG(DatasetLimiting) FROM DataModels WHERE Id = 'SampleDataset' GROUP BY Owner

MIN

Returns the minimum column value.

SELECT MIN(DatasetLimiting), Owner FROM DataModels WHERE Id = 'SampleDataset' GROUP BY Owner

MAX

Returns the maximum column value.

SELECT Owner, MAX(DatasetLimiting) FROM DataModels WHERE Id = 'SampleDataset' GROUP BY Owner

SUM

Returns the total sum of the column values.

SELECT SUM(DatasetLimiting) FROM DataModels WHERE Id = 'SampleDataset'

COUNT

Returns the number of rows matching the query criteria.

SELECT COUNT(*) FROM DataModels WHERE Id = 'SampleDataset'

COUNT(DISTINCT)

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

SELECT COUNT(DISTINCT Name) AS DistinctValues FROM DataModels WHERE Id = 'SampleDataset'

AVG

Returns the average of the column values.

SELECT Owner, AVG(DatasetLimiting) FROM DataModels WHERE Id = 'SampleDataset'  GROUP BY Owner

MIN

Returns the minimum column value.

SELECT MIN(DatasetLimiting), Owner FROM DataModels WHERE Id = 'SampleDataset' GROUP BY Owner

MAX

Returns the maximum column value.

SELECT Owner, MAX(DatasetLimiting) FROM DataModels WHERE Id = 'SampleDataset' GROUP BY Owner

SUM

Returns the total sum of the column values.

SELECT SUM(DatasetLimiting) FROM DataModels WHERE Id = 'SampleDataset'
