Sorting Data
We can sort the data we receive in a specific order. To do this, we first retrieve the data using the SELECT operator and then apply the ORDER BY clause. This clause takes the names of columns based on which the output will be sorted.
Here's the syntax to help us understand:
SELECT columns
FROM table
ORDER BY column_name
Here is the example where we ordering the result by continent column:
123SELECT continent FROM country ORDER BY continent;
It's important to note that when you specify a column with integer values, the sorting will be done in ascending order. For string columns, the sorting will follow alphabetical order.
Also, the ORDER BY clause should be placed just before the LIMIT clause, if a LIMIT clause is included in the query.
Explanation: In the example, you can observe that the ORDER BY clause sorts the data based on the continent column.
1. What is the main purpose of the ORDER BY clause in an SQL query?
2. What is the default sorting order for numeric and string columns when using the ORDER BY clause in SQL?
