PRB: Use ADOX with JetOLEDB to Use Command.Parameters.Refresh (253627)


The information in this article applies to:

  • Microsoft Visual InterDev 6.0
  • ActiveX Data Objects (ADO) 2.0
  • ActiveX Data Objects (ADO) 2.01
  • ActiveX Data Objects (ADO) 2.1
  • ActiveX Data Objects (ADO) 2.1 SP1
  • ActiveX Data Objects (ADO) 2.1 SP2
  • ActiveX Data Objects (ADO) 2.5
  • ActiveX Data Objects (ADO) 2.6
This article was previously published under Q253627

SYMPTOMS

When you use the Adodb.Command.Parameters.Refresh method with an Access stored query, the following error message appears:
ADODB.Command (800A0CC1) Item cannot be found in the collection corresponding to the requested name or ordinal.

CAUSE

ADODB does not support the Command.Refresh method for calling Access queries.

RESOLUTION

To work around this problem, use ActiveX Data Objects Extensions for Data Definition Language and Security (ADOX) with Catalog.Command. This will enable you to use Command.Refresh.

MORE INFORMATION

Paste the following code in a text editor, such as Microsoft Notepad, and save it as an ASP file in the \InetPub\WwwRoot folder. You can then execute this code from the browser to test the Catalog.Command.Refresh method.

NOTE: The code as provided here demonstrates the error. Refer to the comments in the code to avoid the error.
