I have the following table:

ID COL1 COL2 COL3 COL4

1 A NULL 15 NULL
1 A TEST1 NULL NULL
1 A NULL NULL ABC
2 B NULL 10 NULL
2 B TEST2 NULL EFG

I would like to get the following table from the above table

ID COL1 COL2 COL3 COL4
1 A TEST1 15 ABC
2 B TEST2 10 EFG

I have tried self join and checking for null values but so far I haven't been able to get it right. Any suggestions would be appreciated.

[code]
SELECT ID,
COL1,
MAX(COL2) AS COL2,
MAX(COL3) AS COL3,
MAX(COL4) AS COL4
FROM Table
GROUP BY ID,COL1
[/code]
