The following request populates a queue table with values from a base table. The value for the QITS column of the queue table is the default timestamp.

     INSERT INTO orders_qt (productid, quantity, unitprice)
     SELECT productid, quantity, unitprice
     FROM backorders
     WHERE ordernumber = 1002003;

The following request performs a FIFO pop on the orders_qt queue table and stores it into the backorders base table:

     INSERT INTO backorders (productid, quantity, unitprice)
     SELECT AND CONSUME TOP 1 productid, quantity, unitprice
     FROM orders_qt;
