Steve writes "Is it possible to produce a list of the 'top' values for each identifier in a table?
I have the following table;
PointData
------------------
pointID integer (FK, PK)
pointDataTime datetime (PK)
pointDataValue float
I would like to select the pointDataTime of the largest value of pointDataValue for each pointID, using a single query.
In a similar vein, it would be useful to get the pointDataTime of the last value reading for each pointID.
I am running SQL Server 2000 on Windows 2000." |
