What is the method for rearranging the columns in an oracle table?

edit

To rearrange the columns in an Oracle table, you can use the ALTER TABLE statement with the MODIFY clause.

Syntax:

ALTER TABLE table_name MODIFY 
(column_name1 column_definition,
column_name2 column_definition,
...,
column_nameN column_definition);

Example:

Suppose you have a table named "employees" with the following columns:

• emp_id
• emp_name
• emp_salary
• emp_dept

If you want to rearrange the columns in the following order:

• emp_name
• emp_salary
• emp_dept
• emp_id

you can use the following SQL statement:

ALTER TABLE employees MODIFY 
(emp_name VARCHAR2(50),
emp_salary NUMBER(10,2),
emp_dept VARCHAR2(50),
emp_id NUMBER(5));

This statement will modify the table "employees" by rearranging the columns as specified in the MODIFY clause.
