ADO CursorLocation Property


The CursorLocation property sets or returns a long value that indicates the location of the cursor service. It can be set to one of the CursorLocationEnum values. Default value is AdUseServer.

A cursor is used to:
  • control record navigation
  • control the visibility of changes in the database
  • control the updatability of data
Note: A Recordset object inherits this setting from the associated Connection object.

Note: This property is read-only on an open Recordset object, and read/write on a Connection object or on a closed Recordset object.

Syntax

objConnection.CursorLocation
objRecordset.CursorLocation

Example

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("northwind.mdb"))
set rs=Server.CreateObject("ADODB.recordset")
sql="SELECT * FROM Customers"
rs.CursorLocation=adUseClient
rs.CursorType=adOpenStatic
rs.LockType=adLockBatchOptimistic
rs.Open sql,conn
rs.Close
