One of the Column returned as NULL from SQL Server 2008

Question

Hi,
I have written a stored procedure in SQL server 2008. The procedure reads data into a temporary table @MeterWiseConsumptionBetwDates as shown
SELECT @sqlstatement =     'SELECT '''@MeterName''', CAST ( MAX('@Meterfield') AS FLOAT )-CAST ( MIN('@Meterfield') AS FLOAT )
                              FROM KWH
                              WHERE     KWH.timestamp BETWEEN @StDate AND @EndDate'
INSERT INTO @MeterWiseConsumptionBetwDates(MeterName,Consumption)
EXEC sp_executesql @sqlstatement, N'@StDate datetime, @EndDate datetime', @StDate, @EndDate
Now when I execute the stored procedure in SQL Server Management Studio it returns all the columns from the table @MeterWiseConsumptionBetwDates, but when I execute the procedure in MII it returns the values in the Consumption column as null. The MeterName column is returned correctly in both the cases.
Please help.
Thanks

Glad to hear that it is working.  You should be able to use
execute <proc name> '[SD]'
[SD] and [ED]
are the query date tokens, so whatever you have assigned on the Date Range tab will be passed to the query.
