Limiting Results
We know that the SELECT operator can retrieve all rows from a table of all or the specific columns. However, what if we only need to fetch a specific number of rows?
We can do it using the LIMIT clause. It is always used at the end of the query. Here is the syntax for it:
SELECT columns
FROM table
LIMIT number_of_rows;
In the example below, we extract the first 7 rows (in our case, the capitals of the countries) from the column:
123SELECT capital FROM country LIMIT 7;
Swipe to start coding
Write an SQL query to retrieve 3 distinct continent values from the country table.
