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 Notebooks WHERE Id = 'Jq74mCczmFXk1tC10GB'

COUNT(DISTINCT)

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

SELECT COUNT(DISTINCT Id) AS DistinctValues FROM Notebooks WHERE Id = 'Jq74mCczmFXk1tC10GB'

AVG

Returns the average of the column values.

SELECT notebook_displayName, AVG(Reminder) FROM Notebooks WHERE Id = 'Jq74mCczmFXk1tC10GB' GROUP BY notebook_displayName

MIN

Returns the minimum column value.

SELECT MIN(Reminder), notebook_displayName FROM Notebooks WHERE Id = 'Jq74mCczmFXk1tC10GB' GROUP BY notebook_displayName

MAX

Returns the maximum column value.

SELECT notebook_displayName, MAX(Reminder) FROM Notebooks WHERE Id = 'Jq74mCczmFXk1tC10GB' GROUP BY notebook_displayName

SUM

Returns the total sum of the column values.

SELECT SUM(Reminder) FROM Notebooks WHERE Id = 'Jq74mCczmFXk1tC10GB'
