Microsoft SQL Server insert from select query

Question

What I'm trying to do: read the logs and insert the necessary data into 3 different tables that get information from each other.

LOG_ITEM201303 is found on gamelogs db.
Mail_Item_Table, Mail_List_Table, Mail_Message_Table is found on game db.

The Mail Tables are connected via the Indexes.

CHAR_KEY, NAME, ITEMNUM are the values I need to use for my queries.

The query for me to get the data from the logs:

SELECT CHAR_KEY, NAME, ITEMNUM
FROM LOG_ITEM201303
where 
(   
    ITEMNUM = 14317
OR  ITEMNUM = 14318
OR  ITEMNUM = 15478
OR  ITEMNUM = 15479
OR  ITEMNUM = 14301
OR  ITEMNUM = 14302
OR  ITEMNUM = 15476
OR  ITEMNUM = 15477
OR  ITEMNUM = 15018
OR  ITEMNUM = 15019
OR  ITEMNUM = 15020
OR  ITEMNUM = 15021
OR  ITEMNUM = 15022
OR  ITEMNUM = 15023
OR  ITEMNUM = 15024
OR  ITEMNUM = 15025
OR  ITEMNUM = 14437
OR  ITEMNUM = 14438
OR  ITEMNUM = 15656
OR  ITEMNUM = 15657
OR  ITEMNUM = 15658
OR  ITEMNUM = 15659
OR  ITEMNUM = 15660
OR  ITEMNUM = 15661
OR  ITEMNUM = 15662
OR  ITEMNUM = 15663
) AND (KIND = 133) AND (Convert(varchar, OCCUR_TIME,111) < '2013/03/22')

Sample result of logs query above(total actual results are in 600+):

 CHAR_KEY        NAME            ITEMNUM
 -----------+----------------+-----------
 28257      |   clarkailey   |   14438
 894367     |   Wolf         |   15023
 2869858    |   HOPEINME     |   14437

Now I need to automatically insert each row into this query:

 CHAR_KEY        NAME            ITEMNUM
 -----------+----------------+-----------
 2869858    |   HOPEINME     |   14437

(this query shows an example of the 3rd sample data above being inserted...
instead of making this query for each entry is there a way for this to done faster?)

INSERT INTO Mail_Item_Table
(ItemNumber, ItemInfo, ReceiveDate)
VALUES
(14437,       --this is the ITEMNUM
    (SELECT CONVERT(BINARY(16), REVERSE(CONVERT(BINARY(16), 14437)))), NULL)

INSERT INTO Mail_Message_Table
(Message)
VALUES
('Automated Message from the ADMIN.')

INSERT INTO Mail_List_Table
(ReceiverCharKey, MailListIndex, MailItemIndex, MailMessageIndex, Sender, Receiver, SendDate)
VALUES 
(2869858,       --this is the CHAR_KEY
(SELECT TOP 1   MailListIndex+1 as last_entry
 FROM           Mail_List_Table
 WHERE          sender = 'SENDER'
 ORDER BY       MailListIndex DESC),
(SELECT TOP 1   MailItemIndex AS last_entry
 FROM           Mail_Item_Table
 ORDER BY       MailItemIndex DESC),
(SELECT TOP 1   MailMessageIndex AS last_entry
 FROM           Mail_Message_Table
 ORDER BY       MailMessageIndex DESC),
 'SENDER', 
 'HOPEINME', --this is the NAME
 getdate())

My question:

How to automate all this, that the query will read all the logs and insert the data row by row. Thank you very much.

Can I use @variables for this?

Answer 1

You can use the following syntax for inserts

INSERT INTO dbo.Destination (Col1, Col2, Col3)
SELECT Col1, Col2, Col3
FROM dbo.Source

If you had tables with the same columns or a result set that had the same columns as your destination, you don't have to specify columns in the INSERT.

INSERT INTO dbo.Destination
SELECT *
FROM dbo.Source

Both of these are predicated on your Destination table already being created. These are NOT the same as SELECT * INTO dbo.Destination FROM dbo.Source
