In the code below, what I am trying to do is to determine what the value of str_All should be. And then trying to set @strAll = str_All so that I could use it in my SQL.

Question: How can I do something like this?
Dim str_All As String
If chkCustomersWithOrders.Checked Then
         str_All = "(have orders)"
Else
         str_All = "(some have orders)"
End If

 @strAll =str_All
 SQL.ExecQuery("SELECT CustomerID, substring(FirstName + ' ' + LastName + '                                                     ',1,50) +" & " dbo.fnHasOrders (CustomerID) as CustName From tblCustomers Union" & _
  " SELECT '99999', '<All>' + @strAll  From tblCustomers")

Hi,

do you really need to pass the value strAll to @strAll, you can use it like this..

Dim str_All As String
If chkCustomersWithOrders.Checked Then
         str_All = "(have orders)"
Else
         str_All = "(some have orders)"
End If

 @strAll =str_All
 SQL.ExecQuery("SELECT CustomerID, substring(FirstName + ' ' + LastName + '                                                     ',1,50) +" & " dbo.fnHasOrders (CustomerID) as CustName From tblCustomers Union" & _
  " SELECT '99999', '<All>' + " & strAll & "  From tblCustomers")

Use a parameterized query.

btw, please post concise and complete samples. What kind of type is SQL?

samo4fun,

Just because I wanted to see how it is done via parameter, I was trying to use @strAll.


ste5an,

Yes, I should have mentioned SQLEXPRESS12
