我正在尝试使用Ole DB将数据插入到MS SQL Server 2008中。我的插入程序是:
ALTER PROCEDURE [dbo].[table_insert]
@category as bigint
AS
BEGIN
INSERT INTO dbo.table
(category)
VALUES(@category)
SELECT SCOPE_IDENTITY() as id;
END
当我调用该程序时,它会正确执行。插入新行。我使用访问器获取新的行ID:
class DCCRetValueAccessor
{
public:
__int64 id;
BEGIN_COLUMN_MAP(DCCRetValueAccessor)
COLUMN_ENTRY(1, id)
END_COLUMN_MAP()
void ClearRecord()
{
memset(this, 0, sizeof(*this));
}
};
要执行该过程并获取新的行ID,我使用以下代码:
CString cmd;
__int64 newID = -1;
cmd.Format(_T("EXEC [dbo].[alert_settings_insert] @category=%I64d"), value->category);
CCommand<CAccessor<DCCRetValueAccessor>> command;
if(DC_SUCCEEDED(command.Open(m_session, cmd)))
{
if(command.MoveFirst() == S_OK)
{
newID = command.id;
}
else
return -1;
}
else
{
LogError();
return -1;
}
return newID;
问题是,在atldbcli.h中调用GetInterface()后,我在方法Bind()中得到了ASSERT错误,Line:6108,expression:GetInterface()!= 0.
我看不出错误。你能帮我吗? 感谢
答案 0 :(得分:0)
解决方案是添加 SET NOCOUNT ON ;这样的程序:
ALTER PROCEDURE [dbo].[table_insert]
@category as bigint
AS
BEGIN
INSERT INTO dbo.table
(category)
VALUES(@category)
SELECT SCOPE_IDENTITY() as id;
END
