When you use the CreateTableDef method to create a table that is linked to a table in another Microsoft Access database or to an ODBC data source, you cannot set the Attributes property to dbAttachedTable or dbAttachedODBC. These constants are always read-only. When you create the linked table, you must set the Connect property and the SourceTableName property. This automatically sets the Attributes property to dbAttachedTable or to dbAttachedODBC, whichever is appropriate. However, you can set the Attributes property to dbAttachExclusive or dbAttachSavePWD.
Note that once you have appended the table to the database, the Attributes property is read-only.
This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.
The following sample procedure creates a linked table whose Attributes property is dbAttachedTable:
- Start Microsoft Access and create a blank database.
Create a new module and type the following line in the Declarations section if it is not already there:
Type the following procedure:
Sub CreateLinkedTable() Dim dbLocal As Database Dim tbfNewAttached As TableDef Set dbLocal = CurrentDb() Set tbfNewAttached = dbLocal.CreateTableDef("MyEmp") With tbfNewAttached .Connect = ";database=<your path to Northwind>" .SourceTableName = "Employees" End With dbLocal.TableDefs.Append tbfNewAttached End Sub
- To test this function, type the following line in the Debug window, and then press ENTER:
Note that the new linked table is shared. To test the Attributes property of the new table, type the following line in the Debug window, and then press ENTER:
?currentdb.TableDefs("MyEmp").Attributes = dbAttachedTable
This returns the value True to the Debug window.
To create a table that is linked exclusively, change the With...End With statement in the procedure in step 3 to the following:
With tbfNewAttached .Connect = ";database=<your path to Northwind>" .SourceTableName = "Employees" .Attributes = dbAttachExclusive End With
To test the Attributes property of this table, type the following on a single line in the Debug window, and then press ENTER:
?currentdb.TableDefs("MyEmp").Attributes = dbAttachedTable + dbAttachExclusive
The following sample With...End With statement sets the properties of a table linked to an ODBC DSN named "sqltest"; the table is linked to a table named dbo_employee in the remote data source.
Note In the following sample code, you must change UID=
<username> and PWD=
to the correct values. Make sure that the user ID has the appropriate permissions to perform this operation on the database.
With tbfNewAttached .Connect = "ODBC;DSN=sqltest;UID=<username>;PWD=<strong password>" .SourceTableName = "employee" End With
To test the Attributes property of this table, type the following line in the Debug window, and then press ENTER:
?currentdb.TableDefs("MyEmp").Attributes = dbAttachedODBC
For more information about the Attributes property, search the Help Index for "Attributes property."
