Hi,

I have an application where the data sets consists of a Parcel number, an annual interest rate, and an annual percentage rate. Some parcel numbers have both annual interest rates, some only have annual ineterest rates. with the parcel numbers that have both, instead of creating a table placing the annual interest and annual pertage rates on one same data row. The vendor created 2 seperate data rows.
For example:

calulation.Parcel Number: 20394
calculation.annualinterestrate : 20
calculation.annualpercentagerate: NULL

calulation.Parcel Number: 20394
calulation.annual interest rate : NULL
calulation.annual percentage rate: 30

I would like it to be on the same data row, because it it is the same parcel number:

for example:

calulation.Parcel Number: 20394
calulation.annual interest rate : 20
calulation.annual percentage rate: 30

Please help.

Thanks

[code]
SELECT [Parcel Number],MAX([annual interest rate]),MAX([annual percentage rate])
FROM YourTable
GROUP BY [Parcel Number]
[/code]

sorry. I didn't mention that when I run the query I get over 100,000 records. Some Parcels have annual interest rate, and some don't. Some have both, but instead of just updating the annual interest rate column of that specific parcel ( and vice versa), the vendor created a whole new record for it. For example:

calulation.Parcel Number: 20394
calculation.annualinterestrate : 20
calculation.annualpercentagerate: NULL

calulation.Parcel Number: 20394
calulation.annual interest rate : NULL
calulation.annual percentage rate: 30

it shoould be:

calulation.Parcel Number: 20394
calulation.annual interest rate : 20
calulation.annual percentage rate: 30

so do you mean you want to retrive them as single record, which is what i gave you earlier or do you mean to remove the extra record from table after copying the other column info to first record?
