Introduction to SQL

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:

123
SELECT capital FROM country LIMIT 7;
copy
