Answer 1

You can use INSERT...SELECT syntax. Note that you can quote '1' directly in the SELECT part.

INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
SELECT magazine_subscription_id, 
       subscription_name, 
       magazine_id, 
       '1'
FROM tbl_magazine_subscription
ORDER BY magazine_subscription_id ASC 

Answer 2

INSERT INTO mt_magazine_subscription SELECT *
       FROM tbl_magazine_subscription 
       ORDER BY magazine_subscription_id ASC

Answer 3

  INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
  VALUES ( 
      (SELECT magazine_subscription_id, 
              subscription_name, 
              magazine_id,'1' as status
       FROM tbl_magazine_subscription 
       ORDER BY magazine_subscription_id ASC))

Answer 4

INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
VALUES ( 
      (SELECT magazine_subscription_id, 
              subscription_name, 
              magazine_id,'1' as status
       FROM tbl_magazine_subscription 
       ORDER BY magazine_subscription_id ASC));

Answer 5

INSERT INTO destination_table ( 
      Field_1, 
      Field_2, 
      Field_3) 
SELECT Field_1, 
      Field_2, 
      Field_3 
      FROM source_table;

BUT this is a BAD MYSQL

Do this instead:

1. drop the destination table: DROP DESTINATION_TABLE;
2. CREATE TABLE DESTINATION_TABLE AS (SELECT * FROM SOURCE_TABLE);

Answer 6

If there is a primary key like "id" you have to exclude it for example my php table has: id, col2,col3,col4 columns. id is primary key so if I run this code:

INSERT INTO php  (SELECT * FROM php);

I probably get this error:

#1062 - Duplicate entry '1' for key 'PRIMARY'

So here is the solution, I excluded "id" key:

INSERT INTO php ( col2,col3,col4)  (SELECT col2,col3,col4 FROM php2);

So my new php table has all php2 table rows anymore.
