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.

SELECT COUNT(*) FROM OEInvoices WHERE Allowpartialshipments = 'Yes'

COUNT(DISTINCT)

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

SELECT COUNT(DISTINCT InvoiceUniquifier) AS DistinctValues FROM OEInvoices WHERE Allowpartialshipments = 'Yes'

AVG

Returns the average of the column values.

SELECT ApprovedLimit, AVG(AnnualRevenue) FROM OEInvoices WHERE Allowpartialshipments = 'Yes' GROUP BY ApprovedLimit

MIN

Returns the minimum column value.

SELECT MIN(AnnualRevenue), ApprovedLimit FROM OEInvoices WHERE Allowpartialshipments = 'Yes' GROUP BY ApprovedLimit

MAX

Returns the maximum column value.

SELECT ApprovedLimit, MAX(AnnualRevenue) FROM OEInvoices WHERE Allowpartialshipments = 'Yes' GROUP BY ApprovedLimit

SUM

Returns the total sum of the column values.

SELECT SUM(AnnualRevenue) FROM OEInvoices WHERE Allowpartialshipments = 'Yes'
