Hey, do you want to know what are SQL Aggregate Functions is? An aggregate function collapses several rows of a table into one (or more, an original number of rows) while applying a given function to a specified column. The average function on a price column, for example, calculates the average of all prices in the rows of your record set, resulting in one number.

- This is what happens when you use an aggregate function. It makes several rows of the same table into one (or more, if the original number of rows is less than the number of rows that were in the table). When you use the average function on a price column, for example, it calculates the average of all the prices in the rows of your record set. This number is the sum of all the prices in that column (the average price). It's also possible to group the rows by another column, like the order date, to see the average price per day. There are also aggregate functions like min(), max(), count(), sum(), and a bunch of other things, like min() and max() (). Click here for more information, https://partopia.ca/web-design-vancouver/.
