记录集在存储过程执行后关闭

我正在VBA中使用ADO执行存储过程。我正在尝试使用SQL Server 2008中的存储过程的结果填充记录集。下面的VBA示例:

Public Function DoSomething() As Variant()

Dim oDB As ADODB.Connection: Set oDB = New ADODB.Connection
Dim oCM As ADODB.Command: Set oCM = New ADODB.Command
Dim oRS As ADODB.Recordset

oDB.Open gcConn

With oCM
    .ActiveConnection = oDB
    .CommandType = adCmdStoredProc
    .CommandText = "spTestSomething"
    .NamedParameters = True
    .Parameters.Append .CreateParameter("@Param1", adInteger, adParamInput, , 1)
    Set oRS = .Execute
End With

If Not oRS.BOF And Not oRS.EOF Then 'Error thrown here'
    DoSomething = oRS.GetRows()
Else
    Erase DoSomething
End If

oRS.Close
Set oRS = Nothing
oDB.Close
Set oDB = Nothing

End Function

我在第Operation is not allowed when the object is closed行收到错误If Not oRS.BOF...,它向我表明存储过程没有返回结果。

但是,如果我在SSMS中执行存储过程,它将返回一行。 SP遵循:

CREATE PROC spTestSomething
    @Param1 int
AS
BEGIN

    DECLARE @TempStore table(id int, col1 int);

    INSERT INTO table1
        (param1)
        OUTPUT inserted.id, inserted.col1
        INTO @TempStore
    VALUES
        (@Param1);

    EXEC spOtherSP;

    SELECT
        id,
        col1
    FROM
        @TempStore;
END
GO

在SSMS中执行程序的结果是:

id    col1
__    ____
1     1

有人可以帮忙解决记录集关闭/未填写的原因吗?

答案 0 :(得分:18)

根据类似问题:“Operation is not allowed when the object is closed” when executing stored procedure我在评论中建议:

  

我怀疑有两个原因:1)你的sp不包含:SET NOCOUNT ON;和2)你正在处理类型为:table的变量。

Operation is not allowed when the object is closed的最常见原因是该存储过程不包含SET NOCOUNT ON命令,这会阻止额外的结果集干扰SELECT语句。
