ACC97: "...No read permission..." Error When Opening a Secured Database with Code (236878)

SYMPTOMS

In Visual Basic for Applications code, when you try opening a table or query from a secure database with the OpenRecordset method, you may receive the following error message:

Run-time error '3112':
Record(s) can't be read; no read permission on 'tablename'

You receive this error even though you have sufficient permissions to open and view the table or query.

RESOLUTION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Through code, you must define the workgroup information file before opening the secured database. The following code demonstrates how to do this:

Function OpenMyDb()

   Dim WS As Workspace
   Dim DB As Database
   Dim Rs As Recordset

   ' Define the workgroup information file (system database) you will use.
   DBEngine.SystemDB = "C:\Windows\System\MyWkgrp.mdw"

   ' OPTIONAL: Create a workspace with the correct login information
   'Set WS = CreateWorkspace("NewWS", "MyID", "MyPwd", dbUseJet)
   ' OPTIONAL: If you set the workspace object, you can use the new
   '           workspace with the OpenDatabase command. For example:
   'Set Db = WS.OpenDatabase("C:\My Documents\MyDB.mdb")
   '
   Set DB = OpenDatabase("C:\My Documents\MyDB.mdb")
   Set Rs = DB.OpenRecordset("MyTbl")

   Rs.Close
   Set Rs = Nothing
   DB.Close
   Set DB = Nothing
   
   ' OPTIONAL: If you set the WS object, use the following to clean up
   'WS.Close
   'Set WS = Nothing
   
   MsgBox "Done"

End Function

MORE INFORMATION

Although you receive the error mentioned in the "Symptoms" section, you are still able to link manually or import tables and queries from that secure database.

If you are using a macro to open a database, you cannot join the workgroup information file that is required to log on.

Steps to Reproduce Behavior

Create a new workgroup information file named MyWkgrp.mdw.
Open any database, and change the password for the Admin user.
Create a new user named MyID as a member of the Admins group.
Quit and then restart Access. Log on as MyID.
Create a new database named MyDB.mdb and save it in the C:\My Documents folder.
Remove the Admin user from the Admins group.
Add one table to the database and name it MyTbl.
Add a few records to the table.
Give the Users group only Read Data and Read Design permissions for the MyTbl table.
Close MyDb.mdb, and then create a new blank database.

Insert a new module and type the following code:

Function OpenMyDB()

   Dim DB As Database
   Dim Rs As Recordset
 
   Set DB = OpenDatabase("C:\My Documents\MyDB.mdb")
   Set Rs = DB.OpenRecordset("MyTbl")

   Rs.Close
   Set Rs = Nothing
   DB.Close
   Set DB = Nothing

   MsgBox "Done"

End Function

In the Debug window, type the following line, and then press ENTER:
```
OpenMyDB
					
```
Note that you receive the error message mentioned in the "Symptoms" section.
