SQL-Anweisung für diese Abfrage optimieren?

Question

Ich habe zwei Tabellen T1 und T2.

T1 hat ID, F1, F2, F3, F4, F5, F6, F7, F8

T2 haben ID, T1_ID, F1, F2, F3, F4, F5, F6, F7, F8, SUM

Beispiele Daten für T1 und T2

T1 
ID,F1,F2,F3,F4,F5,F6,F7,F8 
    1, 1, 2, 3, 0, 0, 5, 0, 0 
    2, 0, 0, 0, 1, 0, 4, 5, 0 
    3, 4, 1, 3, 2, 0, 0, 0, 5 
    4, 1 ,3, 4, 0, 0 ,0, 0, 0 
    5, 7, 2, 1, 3, 0, 0, 0, 0 
    . 
    . 
    . 
T2 
ID,T1_ID,F1,F2,F3,F4,F5,F6,F7,F8,SUM 
    1, 1, 2, 3, 5, 0, 0, 3, 0, 0,100 
    2, 5, 9, 8, 8, 1, 0, 0, 0, 0,200 
    3, 2, 0, 0, 0, 5, 0, 6, 6, 0,300 
    4, 1 ,3, 4, 2, 0 ,0, 3, 0, 0,255 
    5, 4, 8, 8, 8, 0, 0, 0, 0, 0,155 
    . 
    . 

Select * from T2 wo T1.F1 .... T1.F8 haben (1 und 2 und 3)

Abfrage 1 Datensätze zurückgeben müssen, 2,4

1, 1, 2, 3, 5, 0, 0, 3, 0, 0,100 
    2, 5, 9, 8, 8, 1, 0, 0, 0, 0,200 
    4, 1 ,3, 4, 2, 0 ,0, 3, 0, 0,255 

Ich schaffe diese Abfrage

Select T2.ID,T2.F1,T2.F2,T2.F3,T2.F4.T2.F5,T2.F6,T2.F7,T2.F8,T2.SUM,T1.ID 
from T2 
join T1 on T1.ID = T2.T1_ID 
    where 
    (CASE WHEN (T1_ID.F1 = 1) THEN T2.F1 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 2) THEN T2.F1 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    or 
    (CASE WHEN (T1_ID.F1 = 1) THEN T2.F1 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F2 = 2) THEN T2.F2 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    or 
    (CASE WHEN (T1_ID.F1 = 1) THEN T2.F1 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F3 = 2) THEN T2.F3 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    or 
    (CASE WHEN (T1_ID.F1 = 1) THEN T2.F1 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F4 = 2) THEN T2.F4 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    . 
    . 
    . 
    or 
    (CASE WHEN (T1_ID.F2 = 1) THEN T2.F2 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 2) THEN T2.F1 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    or 
    (CASE WHEN (T1_ID.F2 = 1) THEN T2.F2 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F2 = 2) THEN T2.F2 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    or 
    (CASE WHEN (T1_ID.F2 = 1) THEN T2.F2 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F3 = 2) THEN T2.F3 between 0 and 1000 end) 
and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    . 
    . 
    . 

dies ist zu groß Aussage. Wie kann ich die Aussage optimieren?

Answer 1

SELECT * FROM T2 
WHERE EXISTS ( SELECT N.ID 
       FROM( SELECT T1.ID , T1.F1 AS F 
          FROM T1 
          UNION ALL 
          SELECT T1.ID , T1.F2 AS F 
          FROM T1 
          UNION ALL 
          SELECT T1.ID , T1.F3 AS F 
          FROM T1 
          UNION ALL 
          SELECT T1.ID , T1.F4 AS F 
          FROM T1 
          UNION ALL 
          SELECT T1.ID , T1.F5 AS F 
          FROM T1 
          UNION ALL 
          SELECT T1.ID , T1.F6 AS F 
          FROM T1

          SELECT T1.ID , T1.F8 AS F 
          FROM T1 
          UNION ALL 
         ) N 
       WHERE N.F IN (1, 2, 3) 
         AND N.ID = T2.T1_ID 
       GROUP BY N.ID 
       HAVING COUNT(DISTINCT N.F) = 3 
     );
