Rowset does not support scrolling backward
I am trying to query a MySQL database with the below code:
'declare the variables
Dim Connection
Dim Recordset
Dim SQL
'declare the SQL statement that will query the database
SQL = "SELECT * FROM CUSIP"
'create an instance of the ADO connection and recordset objects
Set Connection = CreateObject("ADODB.Connection")
Set Recordset = CreateObject("ADODB.Recordset")
'open the connection to the database
Connection.Open "DSN=CCS_DSN;UID=root;PWD=password;Database=CCS"
Recordset.CursorType=adOpenDynamic
'Open the recordset object executing the SQL statement and return records
Recordset.Open SQL,Connection
Recordset.MoveFirst
If Recordset.Find ("CUSIP_NAME='somevalue'") Then
MsgBox "Found"
Else
MsgBox "Not Found"
End If
'close the connection and recordset objects to free up resources
Recordset.Close
Set Recordset=nothing
Connection.Close
Set Connection=nothing
Whenever I execute the above I get an error 'rowset does not support scrolling backward', any suggestions?
Solution 1:
adOpenDynamic
is not declared in VBScript and therefore equals Empty
, which gets converted to 0
when you assign the CursorType
property.0
is adOpenForwardOnly
, and forward only does not support moving backwards, an ability the Find
method wants.
You should replace adOpenDynamic
with its literal value:
Recordset.CursorType = 2 'adOpenDynamic
To avoid this class of errors altogether, place Option Explicit
as the first line of your script.
