Tranpose the table rows to column
I have a table which looks like this:
id response_id name value
6 13 gender female
5 13 workingArea Sch
3 12 workingArea IT
4 12 gender male
and I wish to convert into something like this:
response_id workingArea gender
12 IT male
13 Sch female
May I know how 开发者_如何转开发to do this?
Assuming your first table is SOURCETABLE and your second table is TARGETTABLE
INSERT INTO TARGETTABLE(response_id, workingArea, gender)
SELECT a.response_id response_id,
a.value workingArea,
b.value gender
FROM SOURCETABLE a, SOURCETABLE b
WHERE a.response_id = b.response_id
AND a.name <> b.name
AND a.name = 'workingArea'
AND b.name = 'gender'
