Running a sql function in an Excel macro

I have a scalar function I have written in SQL. It takes in 2 date times and spits out our business cycle time.

I'd like to be able to have a macro that will look at two columns of cells and run the function for each row that has data.

IE, I want columns A and B to have a bunch of rows with Date1 and Date2.
I want to run a macro that will put
myDateFunction(A1, B1) into column C1
myDateFunction(A2, B2) into column C2

etc...

If all you want to do is put that function in column C for each row with data try this.

LastRow =Range("A"& Rows.Count).End(xlUp).Row

Range("C1:C" & C).Formula = "=myDateFunction(A1,B1)"

Open in new window

If it's more complicated than that please post further details.

imnorie,
Thanks for the quick response.
I entered the below into the macro

LastRow = Range("A" & Rows.Count).End(xlUp).Row

Range("C1:C" & C).Formula = "=dbo.CycleTimeASIhmmss(A1,B1)"

Open in new window

When I run it, I get a

"Run-time error '1004':
Method 'Range' of object '_Global' failed." error message.
(in debug, it highlights the second line as causing the problem)

Here's the Sample data I used:
A B C
01/13/12      02/01/12
01/27/12      02/03/12
01/16/12      02/08/12
01/16/12      02/08/12

Looking around the web a little bit, I just wanted to be clear that I'm wanting to use a scalar function from SQL. I've noticed a lot of other posts about this topic creating connection strings (this spreadsheet does already have a connection string set up in the data tab if that makes a difference).

imnorie,
Thanks again for your informed response. After some more digging around, i've stumbled across a few similar UDFs that other people have written. I've tweaked it to what I think should work for me, but I keep getting

Comile error:
User-defined type not defined

and the debugger highlights the signature of my function.

Public Function CycleTime(FromDate As Date, ToDate As Date) As String
     
   Dim cn As New ADODB.Connection, cmd As New ADODB.Command, rs As ADODB.Recordset
      cn.Open "Provider=SQLOLEDB;Data Source=MYSERVER;Initial Catalog=MYCATALOG;Integrated Security=SSPI;"
      cmd.ActiveConnection = cn
      cmd.CommandText = "Select dbo.CycleTimeASIhmmss('" & FromDate & "','" & ToDate & "')"
      
      Set rs = cmd.Execute()
      rs.MoveFirst
      CycleTime = rs(0)
End Function

Open in new window

From what I'm reading there's some kind of reference missing (probably something to do with the ADO/sql stuff that's going on). I was hoping you might have an idea of what that would be. If not, thanks for all of your help!

Edit: After some testing, I was able to verify that it was this line causing the problem, so I need to find the right reference for it. I'll update when I find it

Dim cn As New ADODB.Connection, cmd As New ADODB.Command, rs As ADODB.Recordset

Glad you got it running.

How is it performance wise?
