Únete resultados "generados" de dos sentencias SELECT con diferentes esquemas en una tabla

Question

Así que tienen las siguientes instrucciones SELECT:

SELECT COUNT(A.Award) AS US, SUBSTRING(CAST(M.Year as char(4)), 0 , 4) AS Decade 
FROM Movies M, Awards A 
WHERE {SOME WHERE CLAUSE} 
GROUP BY Decade; 

y

SELECT COUNT(*) AS Total, SUBSTRING(CAST(A2.Year as char(4)), 0 , 4) AS Decade 
FROM Awards A2 
WHERE {SOME WHERE CLAUSE} 
GROUP BY Decade; 

El primero de ellos es "generador" una mesa con columnas (US, Decade) y la segunda es "generar" otra tabla con columnas (Total, Decade). Quiero unirme a esas dos tablas de modo que consiga una mesa ( de Estados Unidos, total, década). ¿Cómo puedo hacerlo?

Answer 1

Póngalos en subconsultas y hacer un JOIN:

SELECT a.US, a.decade, b.total FROM 

    (SELECT COUNT(A.Award) AS US, SUBSTRING(CAST(M.Year as char(4)), 0 , 4) AS Decade 
    FROM Movies M, Awards A 
    WHERE {SOME WHERE CLAUSE} 
    GROUP BY Decade) AS a 

INNER JOIN 

    (SELECT COUNT(*) AS Total, SUBSTRING(CAST(A2.Year as char(4)), 0 , 4) AS Decade 
    FROM Awards A2 
    WHERE {SOME WHERE CLAUSE} 
    GROUP BY Decade) AS b 

ON a.decade = b.decade
