SYMPTOMS
When you are using ActiveX Data Objects (ADO), if you use
the
AddNew or
Delete method of the
Recordset object, and you open the recordset with an unspecified lock type,
you may receive one of the following error messages:
Run-time error '3251': Object or provider is not capable of performing
requested operation.
-or-
Run-time error '3251':
The operation
requested by the application is not supported by the provider.
-or-
Run-time error '3251':
Current
Recordset does not support updating. This may be a limitation of the provider,
or of the selected locktype.
CAUSE
By default, ADO recordsets are opened with a lock type of
adLockReadOnly, which does not allow additions and deletions.
RESOLUTION
To allow additions and deletions, open the recordset with a
lock type of either
adLockOptimistic or
adLockPessimistic, as in the following code sample:
Sub DelFirstRec()
Dim rs As ADODB.Recordset
Set rs = New ADODB.Recordset
rs.Open "Select * from TestTable", CurrentProject.Connection, _
adOpenKeyset, adLockOptimistic
rs.MoveFirst
rs.Delete
rs.Close
End Sub
: You can use this sample code to resolve the behavior in the
"Steps to Reproduce Behavior" section of this article.
MORE INFORMATION
Steps to Reproduce Behavior
- In a new Access database, create the following new table
and name it TestTable:
Table: TestTable
----------------------------
Field Name: ID
Data Type: Autonumber
Indexed: Yes (No Duplicates)
Field Name: Name
Data Type: Text
- Open the new table in Datasheet view, and then type the
following test data:
ID Name
-----------------
1 Beverages
2 Condiments
3 Confections
4 Dairy
5 Grains
6 Meat
7 Produce
8 Seafood
- NOTE: The sample code in this article uses Microsoft ActiveX Data
Objects. For this code to run properly, you must reference the Microsoft
ActiveX Data Objects 2.x Library (where 2.x is 2.1 or later.) To do so, click References on the Tools menu in the Visual Basic Editor, and make sure that the Microsoft ActiveX Data Objects 2.x Library check box is selected.
Create a module,
and then type the following line in the Declarations section if it is not
already there: - Type the following procedure:
Sub DelFirstRec()
Dim rs As New ADODB.Recordset
rs.Open "Select * from TestTable", CurrentProject.Connection, adOpenKeyset
rs.MoveFirst
rs.Delete
rs.Close
End Sub
- To test this function, type the following line in the
Immediate window, and then press ENTER:
DelFirstRec
Note that you receive the error message that is mentioned in the
"Symptoms" section of this article. Also, when you check the table, you see
that no records have been deleted.
