使用来自不同表中另一行的数据更新单行或多行

Question

Admin need to approve profile information only then it will be displayed. For this my thought is we need to store the data in a dummy table and after reviewing it by the admin and approves it the data update occurs in the master user table.

So I need to update the master table row using the dummy table row. How to do it using simple update query?

Is there any other simpler method?

I doing it using PHP MySQL

Answer 1

You can insert it to the table like (if both tables are alike):

INSERT INTO MasterTable
  SELECT * FROM DummyTable

A suggestion from my side:

You can add a boolean column to the MasterTable like IsApproved . And set it to false by default.

When selecting records from it, use:

SELECT * FROM MasterTable WHERE IsApproved='true'

So users will not get those records which are not approved. When administrator approves each record, update that record and set IsApproved to true . ie,

UPDATE MasterTable
SET IsApproved='true'
Where ID=ItsID

So, now user user will be able to get that record.
