Aggregate functions operate on values across rows to make calculations such as sum, average, minimum/maximum, and count. These functions take 0 or more rows and produce a single output.
COUNT
Returns the number of rows that match the query criteria.
SELECT COUNT(*) FROM Account WHERE Industry = 'Floppy Disks'
COUNT(DISTINCT)
Returns the number of distinct, non-null field values that match the query criteria.
SELECT COUNT(DISTINCT BillingState) AS DistinctValues FROM Account WHERE Industry = 'Floppy Disks'
AVG
Returns the average of the column values.
SELECT Name, AVG(AnnualRevenue) FROM Account WHERE Industry = 'Floppy Disks' GROUP BY Name
MIN
Returns the minimum column value.
SELECT MIN(AnnualRevenue), Name FROM Account WHERE Industry = 'Floppy Disks' GROUP BY Name
MAX
Returns the maximum column value.
SELECT Name, MAX(AnnualRevenue) FROM Account WHERE Industry = 'Floppy Disks' GROUP BY Name
SUM
Returns the total sum of the column values.
SELECT SUM(AnnualRevenue) FROM Account WHERE Industry = 'Floppy Disks'
