The avg() function has the following syntax: SELECT AVG( column_name ) FROM table_name; The avg() function can be used with the SELECT query for retrieving data from a table.
The average is simply calculated by summing the amounts and divide by the difference between min and max dates for each row.
SQL AVG function is used to find out the average of a field in various records. You can take average of various records set using GROUP BY clause. Following example will take average all the records related to a single person and you will have average typed pages by every person.
AVG() function is an aggregate function that calculates the average value of a numerical dataset that returns from the SELECT statement.
select avg( columnname) from table; This will average all rows. To average a subset, use a where clause. To average for each group (of something) use a group by clause.
