Question

I’m trying to process the following in one sql statement – I want to copy the number of records to the archive table and straight away remove the existing ones from the main table.

Something like:

INSERT INTO `table_archive` 
SELECT * FROM `table_main`
WHERE `id` IN (1, 2, 3, 4)
REMOVE FROM `table_main` WHERE `id` IN (1, 2, 3, 4)

It’s basically like cutting and pasting records from one table to another.

Obviously the above statement is just what I want to achieve – any idea if it’s achievable at all and what sql statement would it be?

Answer 1

as mentioned you need to use several DML commands:

START TRANSACTION;
INSERT INTO `table_archive`  SELECT * FROM `table_main` WHERE `id` IN (1, 2, 3, 4); 
DELETE`table_main` WHERE `id` IN (1, 2, 3, 4); 
COMMIT;
