beginner.. :-)

Hello there

I am a very beginner..

I need to know if this is the write structure for doing this:

1. this func call for 4 other func: is it suppose to look like this?

2. with what i should replace the RETURNS int if its return date & int

thanks

ALTER FUNCTION [dbo].[StatisticsEx2_0Func]

(

@.Date_M_Y smalldatetime ,

@.FK nchar (20) ,

@.BizID int

)

RETURNS int

AS

BEGIN

DECLARE @.ResultVar int

set @.ResultVar = (SELECT

dbo.StatisticsEx_2_1_SingleMonthlySumFunc.A, dbo.Statistics_2_1_SingleAnnualAvgFunc.B, dbo.Statistics_2_1_AllGropsMonthlyTotalFunc.C, dbo.StatisticsEx_2_1_AllGroupsAnnualAvgFunc.D

FROM dbo.Statistics_2_1_AllGropsMonthlyTotalFunc, dbo.Statistics_2_1_SingleAnnualAvgFunc, dbo.StatisticsEx_2_1_AllGroupsAnnualAvgFunc, dbo.StatisticsEx_2_1_SingleMonthlySumFunc)

RETURN @.ResultVar

END

If you want to return more than one value then use Inline Table /Table Valued UDF.

If you use sql server 2005 then you can utilize the UDT (.NET Class) to return as Structure.

Create Function [dbo].[StatisticsEx2_0Func]()

Returns table

as

Return

(

Select 100 i, Cast('1/1/2007' as Datetime) d

)

go

Select * from [dbo].[StatisticsEx2_0Func]()

|||

amm..

the "mother" func suppose to get 3 parm – every child func use 2 param out of the 3

then let the table

so...?

Create Function [dbo].[StatisticsEx2_0Func]()

Returns table

as

Return

(

Select

@.Date_M_Y smalldatetime ,

@.BizID int ,

@.FK

)

go
