    Pass Through Query f/ VB to SQL

    I'm trying to run a pass-through query from a VB form in Excel to SQL Server 7.0. Does my code look right? I'm getting an error saying
    "No Command has been set for the Command Object"



    private Sub cmdQuery_Click()
    Dim Start as date
    Dim Finish as date
    Dim SQL as string

    Dim cmd as ADODB.Command
    Dim rs as ADODB.Recordset
    Dim cnn1 as ADODB.Connection
    ' connection object

    ' on error GoTo errhandle

    Start = txtDate1
    Finish = txtDate2

    SQL = "SELECT ..." & _
    "FROM ..." & _
    "WHERE (date >= #" & Start & "# AND" & _
    "date < #" & Finish & "#)"


    ' connect to your DB
    set cnn1 = new ADODB.Connection
    cnn1.Open "Provider=sqloledb;Data Source=server;Initial Catalog=DB;User Id=user;Password=pass;"

    set cmd = new ADODB.Command
    set cmd.ActiveConnection = cnn1 ' set the command object to point to your opened connection

    With cmd
    .CommandTimeout = 600 '10 minutes
    '.CommandType = adCmdStoredProc
    '.CommandText = "lucent_interval_historical"
    .Parameters.Append .CreateParameter("@start", adDBTimeStamp, adParamInput)
    .Parameters.Append .CreateParameter("@finish", adDBTimeStamp, adParamInput)
    .Parameters("@start").Value = Start
    .Parameters("@finish").Value = Finish
    End With

    set rs = cmd.Execute(SQL)

    rs.Close
    cnn1.Close

    Exit Sub

    ' Select Case Err.Number
    ' Case else
    ' Call MsgBox(Err.Number & " - " & Err.Description)
    ' Exit Sub
    'End Select

    End Sub




    Is my SQL statement being sent at the right place or should I put it in my CommandText?

    Re: Pass Through Query f/ VB to SQL

    Hello:

    You can try this code to get SQL query. I am using Oracle 8i as my database software. I hope this can help.
    I use this code to connect to the database:
    Adodc1.ConnectionString = "Provider=MSDAORA. 1;Password=" & Text2.Text & ";User ID=" & Text1.Text & ";Persist Security Info=True"
    Adodc1.CommandType = adCmdUnknown

    Then I use this code to do the query:
    Adodc1.RecordSource = "Select " & Text3.Text & _
    " from " & Text4.Text & _
    " WHERE " & Text5.Text & "=" & Text6.Text
    Adodc1.Refresh

    I use Adodc1.Record to put a SQL query.

    Good Luck

    I m also facing the same problem.Since i m using MS access.I think that problem is on recordset side.U first set all the required properties of the recordset and then try the same.
    All the best
