ADO Status Property


Field Object Reference Complete Field Object Reference

The Status property returns a FieldStatusEnum value that indicates the status of a Field object. Default value is adFieldOK.

If any updates fail then an error is returned and the Status property indicates the combined values of the operation and error status code. The Status property for each Field can be used to determine why the Field was not added, modified, or deleted.

Problems with adding, modifying, or deleting a Field are reported through this property. For example, if a user deletes a Field, it will be marked for deletion in the Fields collection. If the Update call returns an error because the user tried to delete a Field for which he does not have permission, the Status for this field will be adFieldPermissionDenied or adFieldPendingDelete.

Syntax

objfield.Status

Example

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"

set rs = Server.CreateObject("ADODB.Recordset")
rs.open "Select * from orders", conn

response.write(rs.Fields(0).Status)

rs.Close
conn.close
%>
