Hi,
Need alternate query option for the following,the reason for this complex query is to get the output columns in adjacent style like .. id,V1,V2 ......
SELECT time,V1,V2 FROM
(
(SELECT id,time,value AS V1 FROM sample_table WHERE time="10:00:00") AS T1
LEFT JOIN
(SELECT id,time,value AS V2 FROM sample_table WHERE time="11:00:00") AS T2
ON T1.id=T2.id
) AS TMP_TABLE
Regards,
Sunil
