Question

I am new to SQL Server, I am trying to do something as follows.

Sample code :

SELECT ITEM_ID
FROM \'TABLE_NAME_1\'
WHERE ITEM_STATUS = \'ACTIVE\'

SET @I         


        

Answer 1

based on your question i have created sample code you can use only one query to insert multiple data if you want to insert common data between table 1 and table 2 then use inner join or left join will be fine.

Code

INSERT INTO 'TABLE_NAME_3' (ITEM_ID,PRICE)
SELECT T1.ITEM_ID , T2.PRICE
FROM 'TABLE_NAME_1' AS T1
INNER JOIN 'TABLE_NAME_2' AS T2 ON T2.PRODUCT_ID = T1.ITEM_ID
WHERE T1.ITEM_STATUS = 'ACTIVE' 

Answer 2

Question would be why not use a straight SQL

INSERT 
  INTO 'TABLE_NAME_3' 
       (ITEM_ID
        ,PRICE
       )
 SELECT ITEM_ID,ITEM_PRICE
   FROM 'TABLE_NAME_1' A
   JOIN 'TABLE_NAME_2' B
     ON A.ITEM_ID=B.PRODUCT_ID
  WHERE A.ITEM_STATUS = 'ACTIVE'
