SQL查詢特定格式

Question

需要從表中的數據轉換成特定格式的報告幫助

有人可以建議

這裏是原始數據

Source Table data 

Year ID  Value 
1YR Low  0.048 
1YR High 0.13 
1YR Val  0.09 
3YR Low  0.058 
3YR High 0.096 
3YR Val  0.077 


Output 
     Val  Range 
1 Yr 0.09 0.048 to 0.13 
3 Yr 0.077 0.058 to 0.09 

Answer 1

可能需要稍微完善一些，但這是我認爲你需要：

SELECT val.year, val.value, cast(low.value as varchar(6)) 
+ ' to ' + cast(high.value as varchar(6)) as range 
from yourTable val 
INNER JOIN yourTable low on val.year = low.year 
INNER JOIN yourTable high ON 
val.year = high.year 
    where val.id='val' 
AND low.id='Low' 
AND high.id='High'
