Hi there,

I have an Excel file 2002 format that currently has a
query extracting data from a mainframe file using an ODBC
Connection. All works fine. Now time to progress to the
next level, and have some parameters, to limit the data
coming from the mainframe file.

I have a field on a sheet called "tables" that contains a
department code "001".

Q1. How do I limit the ODBC connection to obtaining only
those records with the department code "001", without
hard coding that into the query (the department may
change).

Q2. How can I programatically create an ODBC connection
to the mainframe table without having to configure the
ODBC driver on each user's PC ?

Thanks in advance.

Hi Gary B,

Hopefully this will get you started

Sub UpdateExternalQuery()
Dim str_SQ1 As String
Dim str_SQ2 As String
Dim str_deptCode As String

' str_deptCode is parameter in query
str_deptCode = "001"

' build a SQL statement
str_SQ1 = "SELECT myqry.* FROM mydb.dbo.myqry myqry "

str_SQ2 = "WHERE myqry.dept_code = '" & str_deptCode& "' "

' handle missing parameters by changing the SQL string
If str_deptCode = "" Then
str_SQ2 = ""
End If

' data_dump is the named range of the query table in Excel
With Range("data_dump").QueryTable
.Connection = _
"ODBC;DSN=myDSN;UID=login;PWD=password;APP=Microso ft® Query;DATABASE=mydb"
.CommandText = Array(str_SQ1, str_SQ2)
.Refresh BackgroundQuery:=False
End With

End Sub

Q2. How can I programatically create an ODBC connection
to the mainframe table without having to configure the
ODBC driver on each user's PC ?

Thanks in advance.

You will notice that the above example uses a predefined DSN. You can use a
file DSN and distribute it with your application. Or you can ask this group
to see if anyone can build DSN connections programmatically :)
