SQL ORDER BY Clause

  • Whenever we want to sort the records based on the columns stored in the tables of the SQL database, then we consider using the ORDER BY clause in SQL.
  • The ORDER BY clause in SQL will help us to sort the records based on the specific column of a table. This means that all the values stored in the column on which we are applying ORDER BY clause will be sorted, and the corresponding column values will be displayed in the sequence in which we have obtained the values in the earlier step.
  • Using the ORDER BY clause, we can sort the records in ascending or descending order as per our requirement. The records will be sorted in ascending order whenever the ASC keyword is used with ORDER by clause. DESC keyword will sort the records in descending order.
  • If no keyword is specified after the column based on which we have to sort the records, in that case, the sorting will be done by default in the ascending order.

Before writing the queries for sorting the records, let us understand the syntax.

Syntax to sort the records in ascending order:

Syntax to sort the records in descending order:

Syntax to sort the records in ascending order without using ASC keyword:

Let us explore more on this topic with the help of examples. We will use the MySQL database for writing the queries in examples.

Consider we have customers table with the following records:

ID NAME AGE ADDRESS SALARY
2 Shiva Tiwari 22 Bhopal 21000
3 Ajeet Bhargav 45 Meerut 65000
4 Ritesh Yadav 36 Azamgarh 26000
5 Balwant Singh 45 Varanasi 36000
6 Mahesh Sharma 26 Mathura 22000
7 Rohit Shrivastav 19 Ahemdabad 38000
8 Neeru Sharma 29 Pune 40000
9 Aakash Yadav 32 Mumbai 43500
10 Sahil Sheikh 35 Aurangabad 68800

Example 1:

Write a query to sort the records in the ascending order of the customer names stored in the customers table.

Query:

Here in a SELECT query, an ORDER BY clause is applied on the column 'Name' to sort the records. ASC keyword will sort the records in ascending order.

You will get the following output:

ID NAME AGE ADDRESS SALARY
9 Aakash Yadav 32 Mumbai 43500
3 Ajeet Bhargav 45 Meerut 65000
5 Balwant Singh 45 Varanasi 36000
1 Himani Gupta 21 Modinagar 22000
6 Mahesh Sharma 26 Mathura 22000
8 Neeru Sharma 29 Pune 40000
4 Ritesh Yadav 36 Azamgarh 26000
7 Rohit Shrivastav 19 Ahemdabad 38000
10 Sahil Sheikh 35 Aurangabad 68800
2 Shiva Tiwari 22 Bhopal 21000

All the records present in the customers table are displayed in the ascending order of the customer's name.

Example 2:

Write a query to sort the records in the ascending order of the addresses stored in the customers table.

Query:

Here in a SELECT query, an ORDER BY clause is applied to the 'Address' column to sort the records. No keyword is used after the ORDER BY clause. Hence, the records, by default, will be sorted in ascending order.

You will get the following output:

ID NAME AGE ADDRESS SALARY
7 Rohit Shrivastav 19 Ahemdabad 38000
10 Sahil Sheikh 35 Aurangabad 68800
4 Ritesh Yadav 36 Azamgarh 26000
2 Shiva Tiwari 22 Bhopal 21000
6 Mahesh Sharma 26 Mathura 22000
3 Ajeet Bhargav 45 Meerut 65000
1 Himani Gupta 21 Modinagar 22000
9 Aakash Yadav 32 Mumbai 43500
8 Neeru Sharma 29 Pune 40000
5 Balwant Singh 45 Varanasi 36000

All the records present in the customers table are displayed in the ascending order of the customer's address.

Example 3:

Write a query to sort the records in the descending order of the customer salary stored in the customers table.

Query:

Here in a SELECT query, an ORDER BY clause is applied on the column ?Salary? to sort the records. DESC keyword will sort the records in descending order.

You will get the following output:

ID NAME AGE ADDRESS SALARY
10 Sahil Sheikh 35 Aurangabad 68800
3 Ajeet Bhargav 45 Meerut 65000
9 Aakash Yadav 32 Mumbai 43500
8 Neeru Sharma 29 Pune 40000
7 Rohit Shrivastav 19 Ahemdabad 38000
5 Balwant Singh 45 Varanasi 36000
4 Ritesh Yadav 36 Azamgarh 26000
6 Mahesh Sharma 26 Mathura 22000
1 Himani Gupta 21 Modinagar 22000
2 Shiva Tiwari 22 Bhopal 21000

All the records present in the customers table are displayed in the descending order of the customer's salary.

Example 4:

Write a query to sort the records in the descending order of the customer age stored in the customers table.

Query:

Here in a SELECT query, an ORDER BY clause is applied on the column 'Age' to sort the records. DESC keyword will sort the records in descending order.

You will get the following output:

ID NAME AGE ADDRESS SALARY
3 Ajeet Bhargav 45 Meerut 65000
5 Balwant Singh 45 Varanasi 36000
4 Ritesh Yadav 36 Azamgarh 26000
10 Sahil Sheikh 35 Aurangabad 68800
9 Aakash Yadav 32 Mumbai 43500
8 Neeru Sharma 29 Pune 40000
6 Mahesh Sharma 26 Mathura 22000
2 Shiva Tiwari 22 Bhopal 21000
1 Himani Gupta 21 Modinagar 22000
7 Rohit Shrivastav 19 Ahemdabad 38000

All the records present in the customers table are displayed in the descending order of the customer's age.
