You can rename an existing table in any schema except the schema SYS. To rename a table you must be either DB owner or Table owner.
Use RENAME TABLE to rename a table.
Syntax: RENAME TABLE table-Name TO new-Table-Name
Ex:- RENAME TABLE EMPLOYEE TO EMPLOYEE_ACT
If you have a view or foreign key that references the table, attempts to rename it will generate an error. Also if there are any check constraints or triggers on the table, attempts to rename it will also generate an error.
RENAME Column: Use the RENAME COLUMN to rename a column in a table.
Ex:- RENAME TABLE EMPLOYEE TO EMPLOYEE_ACT
If you have a view or foreign key that references the table, attempts to rename it will generate an error. Also if there are any check constraints or triggers on the table, attempts to rename it will also generate an error.
RENAME Column: Use the RENAME COLUMN to rename a column in a table.
ex: RENAME COLUMN EMPLOYEE.Employee_ID TO EMP_ID;
You can use ALTER TABLE and RENAME COLUMN to modify Column data type
You can use ALTER TABLE and RENAME COLUMN to modify Column data type
ALTER TABLE EMPLOYEE ADD COLUMN EMP_ID NEWTYPE
UPDATE EMPLOYEE SET EMP_ID = Employee_ID
ALTER TABLE EMPLOYEE DROP COLUMN Employee_ID
RENAME COLUMN t. Employee_ID TO EMP_ID
If a view, trigger, check constraint, foreign key constraint then attempt to rename it will generate an error. Also RENAME COLUMN is not allowed if you have any open cursors that reference the column that is being altered.
If there is an index defined on the column then you can still rename. The index will update automatically to refer by its new name
RENAME Index: Use the RENAME Index to rename an index, you cannot rename indexes in SYS schema
Ex:- RENAME INDEX EMPLOYEE_ID_INDEX TO EMP_ID_INDEX
In case if there are any open cursors that reference the index being renamed then RENAME INDEX is not allowed .
