the having clause in sql is similar to where which filters data but having filters groups based on conditions groups is the key word here so having often accompanies the group by clause so letamp;#39;s imagine we have a table of different food and we have the quantity of those foods and we want to do is sum up that quantity by category so fruits and vegetables and so the result looks something like this the sum by category so we could say is select the category and the sum of the quantity and then group by the category but if we want to filter those groups we could use the having clause so maybe what we add here is having a sum quantity greater than 1800 and what thatamp;#39;s going to do is remove vegetables because that group doesnamp;#39;t meet that condition having can help us filter groups thanks for watching if you like this video click the subscribe button and if youamp;#39;re interested in a sql cheat sheet you can find one over at codybaldwin.com
