このクエリのSQL文を最適化しますか？

Question

私はテーブルT1とT2を2つ持っています。

T1 ID、F1、F2、F3、F4、F5、F6、F7、F8

T2有するID、T1_ID、F1、F2、F3、F4、F5、F6、F7、F8、SUMを有します有するT1.F8 T1.F1 ...（1と2と3）

クエリがレコード1を返す必要

選択* T2からT1と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 
    . 
    . 

ため

としてデータを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 

私は、これはあまりにも大きな文です

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

and(CASE WHEN (T1_ID.F1 = 3) THEN T2.F1 between 0 and 1000 end) 
    .

    . 

このクエリを作成します。 ステートメントを最適化するにはどうすればよいですか？

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

         ) N 
       WHERE N.F IN (1, 2, 3) 
         AND N.ID = T2.T1_ID 
       GROUP BY N.ID
