Question

I have created a database like this

+----------------+------------------+
|   name         | password         |
+----------------+------------------+
|   john         | ********         | 
+----------------+------------------+
|   james        |  &*^^%^          |
+----------------+------------------+

Is there any way to create a new table row by column friend,messages, and message from for john and james and other those who join my site?

Answer 1

You could add those columns to your table, but putting that kind of information in the user table is a bad idea.

You should create new tables and use a JOIN to fetch the data:

First, add an ID column to your existing table.

|----------------|------------------|------------------|
|   ID           | user             | password         | 
|----------------|------------------|------------------|

Then, create a new table with the wanted columns:

Table friends:

• ID
• USER_ID_FRIEND
• USER_ID_FRIENDEE

Table messages

• ID
• USER_ID_FROM
• USER_ID_TO
• DATE_SENT
• READ
• MESSAGE_TXT
