Vælg Records flere gange fra tabellen

SELECT Location 
FROM Table1
  CROSS JOIN
    ( VALUES (1),(2),(3),(4)
    ) AS four(dummy)

Hvis 4 er ikke en konstant, men (som @xQbert bemærkede/spurgte) er antallet af rækker i tabellen, kan du bruge dette:

SELECT a.Location 
FROM Table1 AS a
  CROSS JOIN
     Table1 AS b

Hvis du ikke har Table1 men enhver (hvor kompleks) forespørgsel, du kan bruge denne til 4 kopier:

SELECT Location 
FROM (
       SELECT Location       --- complex query here
       ...                   --- inside parenthesis
     UNION 
       SELECT Country
       ...
     ) AS Table1
  CROSS JOIN
    ( VALUES (1),(2),(3),(4)
    ) AS four(dummy)

eller dette for n kopier:

WITH cte AS
  ( SELECT Location       --- complex query here
    ...                   --- inside parenthesis
    UNION 
    SELECT Country
    ...
  )
SELECT a.Location 
FROM cte AS a
  CROSS JOIN
     cte AS b
