列の値に基づいて新しい列を一時テーブルに追加する

Question

以下の表から一時テーブルを作成したいとします。

------------------------|-------- 
Date     | Length 
------------------------|-------- 
2014-08-28 00:00:00.000 | 1.5 
2014-08-28 00:00:00.000 | 2.6 
2014-08-28 00:00:00.000 | 1.5 
2014-08-28 00:00:00.000 | 3.3 
2014-08-28 00:00:00.000 | 1.1 
2014-08-28 00:00:00.000 | 8.5 
2014-08-28 00:00:00.000 | 8.6 
2014-08-28 00:00:00.000 | 11.3 

そして、一時テーブルを次のようにしてください。

Date     | Length | Length_Range 
------------------------|---------|-------------- 
2014-08-28 00:00:00.000 | 1.5 | 1-4 
2014-08-28 00:00:00.000 | 2.6 | 1-4 
2014-08-28 00:00:00.000 | 6.5 | 5-10 
2014-08-28 00:00:00.000 | 3.3 | 1-4 
2014-08-28 00:00:00.000 | 1.1 | 1-4 
2014-08-28 00:00:00.000 | 8.5 | 5-10 
2014-08-28 00:00:00.000 | 8.6 | 5-10 
2014-08-28 00:00:00.000 | 11.3 | 11-15 

[Length_Range]を定義できます。

Answer 1

使用case：

select t.*, 
     (case when length >= 1 and length < 4 then '1-4' 
      when length < 10 then '5-10' 
      when length < 15 then '11-15' 
      else '16+' 
     end) as length_range 
into #temp_t 
from t; 

Answer 2

CREATE TABLE #TABLE1 
    ([DATE] DATETIME, [LENGTH] FLOAT) 
INSERT INTO #TABLE1 
    ([DATE], [LENGTH]) 
VALUES 
    ('2014-08-28 00:00:00', 1.5), 
    ('2014-08-28 00:00:00', 2.6), 
    ('2014-08-28 00:00:00', 1.5), 
    ('2014-08-28 00:00:00', 3.3), 
    ('2014-08-28 00:00:00', 1.1), 
    ('2014-08-28 00:00:00', 8.5), 
    ('2014-08-28 00:00:00', 8.6), 
    ('2014-08-28 00:00:00', 1.3) 

SELECT *,CASE 
WHEN LENGTH BETWEEN 1 AND 4 THEN '1-4' 
WHEN LENGTH BETWEEN 5 AND 10 THEN '5-10' 
WHEN LENGTH BETWEEN 11 AND 15 THEN '11-15' END AS LENGHT_RANGE 
FROM #TABLE1 

Date     Length LENGHT_RANGE 
2014-08-28 00:00:00.000 1.5   1-4 
2014-08-28 00:00:00.000 2.6   1-4 
2014-08-28 00:00:00.000 1.5   1-4 
2014-08-28 00:00:00.000 3.3   1-4 
2014-08-28 00:00:00.000 1.1   1-4 
2014-08-28 00:00:00.000 8.5   5-10 
2014-08-28 00:00:00.000 8.6   5-10 
2014-08-28 00:00:00.000 1.3   1-4

あなたは、Select ...構文

CREATE TABLE temp_table AS 
SELECT [date], [length], 
     CASE 
     WHEN length BETWEEN 1 AND 4 THEN '1-4' 
     WHEN length BETWEEN 5 AND 10 THEN '5-10' 
     WHEN length BETWEEN 11 AND 15 THEN '11-15'
