What is the difference between a VBA private/public function and a SQL Server function?

I'm jumping from Access to SQL Server and VBA to C# sharp now.
In the past when I had an update query I could do the following SQL -

UPDATE tblColTypes SET tblColTypes.Family = Replace_Symbols([Family])
WITH OWNERACCESS OPTION;

And the Replace_Symbols would be in a VBA module as:

Public Function Replace_Symbols(sVlu As String) As Variant
On Error GoTo Err_This
 
  sVlu = Replace(sVlu, "-", "")
  sVlu = Replace(sVlu, "/", "")
  sVlu = Replace(sVlu, Chr(34), "")
 
  Replace_Symbols = sVlu
 
Exit_This:
    Exit Function
   
Err_This:
    Resume Exit_This
End Function

How would I do this in C# using Visual Studio 2008 - do I create a SQL Server function in under my Server Explorer window?

yes, a function would do:
create Function dbo.Replace_Symbols(sVlu as varchar(max) ) returns varchar(max)
as 
begin
 set @sVlu = replace(@sVlu, '-', '')
 set @sVlu = replace(@sVlu, '/', '')
 set @sVlu = replace(@sVlu, '''', '')
 reutrn @sVlu 
End 

Open in new window

2 notes:

? the functions are created "per database", so make sure you are connected to the correct database when creating the function.
? to use the function in the sql code, you need to prefix with the owner name (dbo.) like in the create:

select dbo.Replace_Symbols('123-456/789''0') data

I would suggest taking a look at LINQ ... since you are making a fresh start

I get an error - Incorrect syntax near 'sVlu'
Must declare the scalar variable "@sVlu"
Must declare the scalar variable "@sVlu"
Must declare the scalar variable "@sVlu"
ok

I'm doing this inside of Visual Studio 2008 - under Server Explorer - under Database.mdf - Add New Functions...

create Function dbo.Replace_Symbols(@sVlu as varchar(max) ) returns varchar(max)
as 
begin
 set @sVlu = replace(@sVlu, '-', '')
 set @sVlu = replace(@sVlu, '/', '')
 set @sVlu = replace(@sVlu, '''', '')
 reutrn @sVlu 
End
