ACC2000: Output of Stored Procedure Truncated in Access Client/Server

• Microsoft Access 2000

SYMPTOMS

When you run certain stored procedures from a Microsoft Access project, the output of the procedure is truncated in Datasheet view. If you run the same procedure from one of the SQL Server Client Tools, all rows are returned as expected.

CAUSE

If a stored procedure returns multiple result sets in its output, an Access project returns only the first result set to Datasheet view. The user interface in an Access project is not designed to return multiple result sets.

RESOLUTION

Use alternate tools to run stored procedures that return multiple result sets, such as SQL Server Query Analyzer or OSQL.

MORE INFORMATION

To determine if Access Client/Server can display the entire output of a particular stored procedure, follow these steps.

1. Open an Access project that is connected to the user database which contains the stored procedure that you want to examine. If you need to test a system stored procedure, open any Access project connected to a user database.



2. Create a module and type the following line in the Declarations section if it is not already there:




Option Explicit 

3. Type the following procedure:




 
Sub CheckOutput(strProcName As String)
    
   Dim conn As New adodb.Connection
   Dim com As New adodb.Command
   Dim rs As New adodb.Recordset
   Dim i
    
   On Error GoTo errorTrapper
   
   Set conn = CurrentProject.Connection
   com.ActiveConnection = conn
    
   With com
      .CommandText = strProcName
      .CommandType = adCmdStoredProc
   End With
    
   Set rs = com.Execute
       
   Do Until rs Is Nothing
      i = i + 1
      Set rs = rs.NextRecordset
      If i > 1 Then
         MsgBox "Stored Procedure " & strProcName & _
           " contains more than one resultset. " & vbCrLf & _
           "The results will therefore be truncated when displayed.", _
           vbInformation
         Exit Sub
      End If
   Loop
        
   Exit Sub
    
errorTrapper:
   If Err.Number = 3251 Then
      MsgBox "Stored Procedure " & strProcName & _
        " contains only one resultset. " & vbCrLf & _
        "It therefore should be displayed correctly.", _
        vbInformation
   Else
      MsgBox Err.Description & Err.Number, vbCritical, "Error"
   End If
    
End Sub 

4. Open the Immediate window and type the following line of code, substituting StoredProcName with the name of the stored procedure that you want to examine:




Call Checkoutput("StoredProcName") 

Press ENTER.

Steps to Reproduce Behavior

1. Open an Access project connected to the sample database NorthwindCS.adp.



2. Use the following SQL to create a new stored procedure:




   CREATE PROCEDURE "TestSProc"
   AS
   EXEC sp_help 'Customers' 

Save the stored procedure.


3. Run the stored procedure and note that one row is returned in Datasheet view.



4. Open SQL Server Query Analyzer, connect to the NorthwindCS database on your SQL Server, and run the following code:




EXEC TestSproc
