Excel VBA: ODBC SQL server driver query timeout expired

Question

I have the below VBA query used in Excel 2016 that exacutes a MS Sql stored procedure, sometimes it executes smoothly and returns the recordset, but more often I get an error

Answer 1

After weeks of testing various code changes, we found that when changing the SQL call to QueryTable method instead of CopyFromRecordset method, it is working fine.

So I am pasting the code if anyone needs it in future.

Sub GetDataset3()

Dim cn As ADODB.Connection
Dim Rs As ADODB.Recordset
Dim UID, PWD, SRV As String
UID = "userId"
PWD = "passworD"
SRV = "192.168.1.1"

If Sheets("data").QueryTables.Count = 0 Then
     Sheets("data").Cells.Select
     Selection.ClearContents

     Dim Str As String 'adds backround query
     Str = ""
     For Each cell In Range("A1:A10").Cells
     Str = Str & Chr(10) & cell
    Next

      With Sheets("data").QueryTables.Add(Connection:="ODBC;UID=;PWD=;DRIVER=SQL 
        Server;SERVER=SRV", Destination:=Range("a2"))
        .CommandText = "select 1"
        'BackgroundQuery = True
        '.Refresh BackgroundQuery = True
        .FieldNames = False
        .AdjustColumnWidth = False
      End With
End If

 With Sheets("data").QueryTables(1)
   .Connection = "ODBC;DRIVER=SQL Server;SERVER=" & SRV & 
   ";database=myDatabaseName;UID=" & UID & ";Pwd=" & PWD & 
   ";Trusted_Connection=no;APP=Microsoft Office"
   .CommandText = ("Get_dataset2 '" & Range("dateFrom") & "' ,'" & 
    Range("dateTo") & "' ")
    BackgroundQuery = True
    .Refresh BackgroundQuery:=False

 End With

End Sub
