HomeDatabaseOracleHow to arrange in reverse order in oracle

In Oracle, reverse sorting can be achieved through the ORDER BY clause: use the ORDER BY column_name DESC syntax, where column_name is the name of the column to be sorted. For example: SELECT first_name, last_name FROM employees ORDER BY last_name DESC.

How to arrange in reverse order in oracle

Reverse sorting in Oracle

In Oracle, you can use ORDER BY clause to sort the data in reverse order. The syntax is as follows:

<code>SELECT column_name(s)
FROM table_name
ORDER BY column_name(s) DESC;</code>

where:

  • column_name is the column name to be sorted.
  • DESC Specifies reverse order.

Example

Suppose we have a table named employees with the following columns:

  • employee_id
  • ##first_name
  • last_name
To press

last_name To sort the columns in reverse order, you can use the following query:

<code>SELECT first_name, last_name
FROM employees
ORDER BY last_name DESC;</code>
The result set will be displayed in the following order:

<code>+-----------+------------+
| first_name | last_name  |
+-----------+------------+
| John       | Smith      |
| Jane       | Doe        |
| Bob        | Jones      |
| Alice      | Brown      |
+-----------+------------+</code>

Additional Notes

    You can specify multiple columns in the
  • ORDER BY clause for multi-column sorting.
  • You can also use the
  • ASC keyword to specify ascending sorting.
  • You can use aliases in the
  • SELECT clause to simplify the column names of the result set.
