Question

let’s said I have the following data:

ID         Key        String        Number

1          Name       A             -1
1          Age        ''            30  
1          Sex        Male          -1
2          Name       B             -1 
2          Age        ''            20
2          Sex        Female        -1  

I wonder if we can use Pivot to produces the following data

ID          Name        Age           Sex
1           A           30            Male
2           B           20            Female

Any helps would be appreciated!

Might be easier to do this?

SELECT id
,MAX(CASE WHEN Key = 'Name' THEN string END) as name
,MAX(CASE WHEN Key = 'Age' THEN number END) as age
,MAX(CASE WHEN Key = 'sex' THEN string END) as sex
FROM table
GROUP BY id
