PostgreSQL – How to Rename a Table

ByAdmin

To rename a table in PostgreSQL, you can use the ALTER TABLE statement with the RENAME TO clause. Here’s the basic syntax:

ALTER TABLE current_table_name RENAME TO new_table_name;

Replace current_table_name with the name of the table you want to rename, and replace new_table_name with the new name you want to give to the table.

Here’s an example of how to use this syntax to rename a table:

ALTER TABLE old_table RENAME TO new_table;

After executing this SQL statement, the table will be renamed from “old_table” to “new_table.” Please note that you need appropriate permissions to rename tables in PostgreSQL.
