PRB: Multiple Statements in Stored Procedure Causes Forward-Only/Read-Only Recordsets
This article was previously published under Q246636
Using ActiveX Data Objects (ADO) and the Microsoft OLEDB Provider or ODBC Driver for SQL Server, to retrieve a recordset from a stored procedure using Server-side Cursors, returns a Forward-only/Read-only recordset if that stored procedure contains anything other than a single SELECT statement. When the recordset is edited, the following run-time error occurs:
3251 "Provider Does Not Support This Operation"
SQL Server cannot provide schema information necessary for updates if the stored procedure contains more than just a SELECT statement.
You can use client-side cursors in order to get a read-only Static cursor, which allows scrolling and bookmarks. You will have to manage updates yourself.
Steps to Reproduce Behavior
Use these steps to reproduce the problem:
- Create the following Stored Procedure in SQL Server 7.0 under the Pubs database.
CREATE procedure Test
@f int
as
if @f = 2
begin
Select * from authors
End
- Start a new Visual Basic Standard EXE project. Form1 is added by default.
- From the Project menu, click References, and then select Microsoft ActiveX Data Objects.
- Place the following code in Form1:
Private Sub Form_Load()
Dim strSQL As String
Dim cn as ADODB.Connection
Dim rst As ADODB.Recordset
Set cn = New ADODB.Connection
Set rst = New ADODB.Recordset
cn.ConnectionString = "Provider=SQLOLEDB;Data Source=Server;User ID=UserName;Password=Password;Initial Catalog=pubs"
cn.Open
strSQL = "exec Test 2"
rst.Open strSQL, cn, adOpenKeyset, adLockBatchOptimistic, adCmdText
rst("au_lname") = "xxxxx" 'Error Occurs Here
rst.UpdateBatch
rst.MoveNext
End Sub
- Run the Project.
RESULT: This error occurs:
Run-time Error '3251': Provider Does Not Support This Operation.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
