Alter Table in PostgreSQL
Welcome to LearnWithMe!
In today’s video, we are learning ALTER TABLE in PostgreSQL — one of the most important DDL commands used to change an existing table structure.
You will understand how to:
✔️ Add a new column to a table
✔️ Rename a column
✔️ Change data type of a column
✔️ Drop (delete) a column
✔️ Rename a table
These commands are very helpful when you want to modify your table without deleting it.
