Create Table Inherits PostgreSQL

In this article, I will talk about using the INHERIT feature while creating a table and the details about it.

Let’s create our field table INHERITS from our personnel_name table.

We created both tables. As a result of this process, there are number and homeaddress columns in our personnel_communication table, but we can see our personnel_name columns in the personnel_communication table because we are doing INHERIT.

We can enter data into both tables by performing operations such as select, insert, update and delete in the INHERIT table.

Let’s insert our staff communication table and check if our first table is also affected by this insertion process.

Let’s check if data has been added to our personnel_name table:
