Aggregate Functions
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 Applications WHERE Sid = 'AP5ddf534702934bd3a446d293e8cdeb1f'
COUNT(DISTINCT)
Returns the number of distinct, non-null field values matching the query criteria.
SELECT COUNT(DISTINCT Sid) AS DistinctValues FROM Applications WHERE Sid = 'AP5ddf534702934bd3a446d293e8cdeb1f'
AVG
Returns the average of the column values.
SELECT Name, AVG(AnnualRevenue) FROM Applications WHERE Sid = 'AP5ddf534702934bd3a446d293e8cdeb1f' GROUP BY Name
MIN
Returns the minimum column value.
SELECT MIN(AnnualRevenue), Name FROM Applications WHERE Sid = 'AP5ddf534702934bd3a446d293e8cdeb1f' GROUP BY Name
MAX
Returns the maximum column value.
SELECT Name, MAX(AnnualRevenue) FROM Applications WHERE Sid = 'AP5ddf534702934bd3a446d293e8cdeb1f' GROUP BY Name
SUM
Returns the total sum of the column values.
SELECT SUM(AnnualRevenue) FROM Applications WHERE Sid = 'AP5ddf534702934bd3a446d293e8cdeb1f'
