T-SQL ORDER BY

ORDER BY Clause sorts the database in increasing or decreasing order. To sort multiple columns at once, separate the column names by the operator (,) operator.

• ORDER BY sorts the data in ascending order by default.
• The DESC keyword is used to sort the data in descending order and ASC keyword is used to sort the database in ascending order.

Syntax of ORDER BY Clause:

Here: table_name: Name of the table.
column_name: Column of the database.
|: Use ASC or DESC to sort in ascending or descending order

Example:

Consider the CUSTOMERS table which has the below records –

ID	NAME	AGE	ADDRESS	SALARY
01	William	32	Karachi	72000
02	Avery	24	London	34000
03	Jackson	34	Paris	12000
04	Harper	20	United state	15000
05	Ella	22	Islamabad	33000
06	Monty	23	Turkey	42000
07	Mason	26	Saudi	50500

Example 1:

Below command is the example, which sorts the result in ascending order by NAME and the SALARY.

ID	NAME	AGE	ADDRESS	SALARY
02	Avery	24	London	72000

04	Harper	20	New York	12000
03	Jackson	34	Paris	15000
07	Mason	26	Saudi Arabia	33000
