Select Only Few Rows





Our table is pretty small, so if we wanted to get some information about Volkswagens, we could select all rows and just ignore the extra few which contain other brands. But what if our table consisted of thousands of rows?

SELECT * FROM user WHERE id = 100;
Look what happened. We've added WHERE and a condition. The simplest condition looks like the one in our example - we want to retrieve information about a user with a specific id (100), so we use the equality (id = 100).


SELECT * FROM table_name WHERE column_name=value;


Execute Below code

SELECT * FROM car WHERE production_year=1999;
