Access To SQL Server Query Translation

Hi,

I'm trying to convert MS Access 97 .mdb application to Access 2003 .adp
application with SQL Server as Backend.

I'm having trouble converting Access Query into SQL Query. The Query is
given below:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~
SELECT DISTINCTROW Buildings.BuildingNumber,
First(Buildings.BuildingName) AS FirstOfBuildingName,
First(OwnershipCodes.OwnershipCode) AS FirstOfOwnershipCode,
First(OwnershipCodes.OwnershipDesc) AS FirstOfOwnershipDesc,
First(CityCodes.CityName) AS FirstOfCityName,
First(CountyCodes.CountyName) AS FirstOfCountyName,
First(Buildings.Address) AS FirstOfAddress,
First(Buildings.YearConstructed) AS FirstOfYearConstructed,
First(Buildings.DateOccupancy) AS FirstOfDateOccupancy,
First(Buildings.NumberLevels) AS FirstOfNumberLevels,
First(Buildings.BasicGrossArea) AS FirstOfBasicGrossArea,
Sum(Rooms.AssignableSquareFeet) AS SumOfAssignableSquareFeet,
First(Buildings.UnrelatedGrossArea) AS FirstOfUnrelatedGrossArea,
First(Buildings.SpecialArea) AS FirstOfSpecialArea,
First(Buildings.CoveredUnenclosedGrossArea) AS
FirstOfCoveredUnenclosedGrossArea
FROM CountyCodes INNER JOIN (OwnershipCodes INNER JOIN (ConditionCodes
INNER JOIN ((CityCodes INNER JOIN Buildings ON CityCodes.CityCode =
Buildings.CityCode) LEFT JOIN Rooms ON Buildings.BuildingNumber =
Rooms.BuildingNumber) ON ConditionCodes.ConditionCode =
Buildings.ConditionCode) ON OwnershipCodes.OwnershipCode =
Buildings.OwnershipCode) ON CountyCodes.CountyCode =
CityCodes.CountyCode
GROUP BY Buildings.BuildingNumber;

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~

Please can any one tell me substitue for First Function in Acess to SQL
Function.

Any help is appreciated.
Thanks,
S
