Delete a number of records given by the number of records in a table

Question

I have a table variable called @workorders , this table are filled by a query:

DECLARE @workorders table
(id_workorder VARCHAR(100));
INSERT INTO @workorders SELECT DISTINCT(id_workorder) FROM CampaingControl WHERE id_campaing = @id;
--get each record of the table @workorders and delete of another table

Then, what I want is to go through each record of the table @workorders and delete a record with the value of the current record.

The table where I want to delete the records is called WorkOrders , this table have a column called id_workorder , for example:

Assuming the table variable @workorders have 3 records:

• OT-001-16
• OT-002-16
• OT-005-16

I need to implement a kind of while loop, to get each record on the table @workorders and for each record delete on the table WorkOrders where id_workorder = @workorders (id_workorder VARCHAR(100))(Current record) .

Answer 1

Can you not simply INNER JOIN the @workorders table in your DELETE statement?

DELETE w 
FROM workorders w INNER JOIN @workorders tw ON w.id_workorder = tw.id_workorder
