SQL - AVG


The AVG aggregate function selects the average value for certain table column.

Have a look at the SQL AVG syntax:

SELECT AVG(Column1)
FROM Table1

If we want to find out what is the average SaleAmount in the Sales table, we will use the following AVG statement:

SELECT AVG(SaleAmount) AS AvgSaleAmount
FROM Sales

which will result in the following dataset:

AvgSaleAmount
$195.73
