This is a waste of time. Your variable is lost as soon a the SQL statement ends, so there's no value in setting it. You can remove it from your code. Just do set txn_no = txn_no + 1.

Also, VB6 is rubbish, no-one uses it, it's been obsolete for a decade. You're wasting your time learning it.

Try this..

VB

Dim CN As New ADODB.Connection
Dim cmd As New ADODB.Command

''' Connect your database connection
CN.Open "Connection String"

With cmd
    .ActiveConnection = CN ' set the connection object
    .CommandType = adCmdStoredProc ' set the stored procedure command type
    .CommandText = "UpdateTable"  ' set the name of stored procedure
    .Execute                       ' execute the sql statement in stored procedure
End With
Set cmd = Nothing
CN.Close
Set CN = Nothing
