उत्तर
ORDER BY clause
The ORDER BY clause in SQL is used to sort the data in either ascending or descending based on one or more columns.
1. By default ORDER BY sorts the data in ascending order.
2. We can use the keyword DESC to sort the data in descending order and the keyword ASC to sort in ascending order.
The ORDER BY clause is used as:
SELECT <column-name> [,<column-name>,….] FROM <table-name> ORDER
BY <column1>,<column2>, …ASC\ DESC;
For example :
To display the students in alphabetical order of their names, the command is used as
SELECT * FROM Student ORDER BY Name;
The above student table is arranged as follows :
| Admno | Name | Gender | Age | Place |
| 104 | Abinandh | M | 18 | Chennai |
| 101 | Adarsh | M | 18 | Delhi |
| 102 | Akshith | M | 17 | Bangalore |
| 100 | Ashish | M | 17 | Chennai |
| 103 | Ayush | M | 18 | Delhi |
| 106 | Devika | F | 19 | Bangalore |
| 107 | Hema | F | 17 | Chennai |
| 105 | Revathi | F | 19 | Chennai |
