Oracle Connection Passing to functions in MSAccess VBA

I am running several functions that connect to an oracle db and run sql. I am trying to figure out how to open the ODBC connection to oracle once, and pass it to each of the functions that need to run sql on the oracle db.  Currently I am establishing the connection in each function, causing the user to need to enter a password with each new connection.

Thanks for any help,
Lynn
Sub RunReport(reportType As String, sTime As Variant)

Dim strTime As Variant

strTime = sTime
    
      If reportType = "Terminating" Then
    
        
      ' Pass ACSCon
          'Get terminating accounts from ACCOUNTS
          Call GetACSAccounts(strACSConnectionACS(strServerName))
         
         'Get Terminating dates from TRANS
          Call GetTRANS(strACSConnectionACS(strServerName))
          
        ' Pulling TRAN names of tranDate userid
          Call GetTranNames(strACSConnectionACS(strServerName))
      
      Else
         
         'Get exceptions accounts from ACCOUNTS
          Call GetACSExceptions(strACSConnectionACS(strServerName))
      
      End If

    'Update Regions
    Call getRegions(reportType)
    
    'get user filter selections on form
    Call GetUserFilter(reportType, strTime)

End Sub

This is how I do it in SQL Server .... Oracle will probably use the same concept.  You just need to find the format of the Oracle connection string.  

Basically in Access you will open a QueryDef for your SQL Query and set the connection string as shown below.

Dim qdef As QueryDef
Dim StrSQLConn as String
Set qdef = CurrentDb.QueryDefs("YourQueryNameHere")

strSQLConn = "ODBC;Driver={SQL Server};Server=SSSSS;Database=DDDDD;Uid=UUUUU;Pwd=PPPPP;"

qdef.Connect = strSQLConn
qdef.Close

Then run your query.
