Default Help! Detect if linked table is available

I am working with an external vendor that provides a "window" into their DB2 mainframe that is updated nightly. I have a gazillion automated reports that need to run as soon as that window is updated. Currently, they maintain a table that holds information on when each table was last updated, but they want to get rid of it. Instead they propose to make the "window" tables temporarily unavailable while they are being updated each night. Then they will be available as soon as the update is complete. They suggest that we just check to see if the tables are available and kick off the reports as soon as they are. We currently link to the tables via ODBC. Can someone please provide some sample code to check to see if a linked table is available? VBA is perfectly fine, but I'm currently limited to Access/VBA in Access.

Thanks!!
Grant

I do not know if there is such a thing. Maybe someone else does. Now, the mainframe is updating the table on a set schedule. Find out at what time the mainframe finishes and set-up a task on a server to run an access database right after that is complete. Set-up a macro to run each of your reports (I am assuming that you are exporting them). then create a form that starts with your access database and put this code on the Load event

Private Sub Form_Load()
    Dim stDocName As String

    stDocName = "YourMacroName"
    DoCmd.RunMacro stDocName
End Sub

This should run all of your reports.

The problem is that the update job is not consistent. So if the reports run and the job hasn't completed or hasn't run at all, they go out blank. Bad for a client-facing app. I already have in place what you suggested for some other reports.
