Question

我想在运行时更改ssis中的连接管理器连接，以便它使用连接字符串连接并给我结果。但它给了我这个错误我已在数据流任务???????

上将延迟验证属性设置为false

Answer 1

为此目的使用ADO.NET托管连接。我有类似的情况，只是创建了第二个连接管理器，其参数与OLE DB相同。

此外，不是更改脚本任务中的连接字符串，而是参数化连接管理器（右键单击\ parametrize）。如果您需要多个参数集，请使用多个连接管理器。

使用托管conn管理器，这将是您在代码中打开连接的方式：

SqlConnection GetConnection(string ConnMgrName)
{
    ConnectionManager cm = Dts.Connections[ConnMgrName];
    SqlConnection conn = (SqlConnection)cm.AcquireConnection(null);
    return conn;
}

Answer 2

在脚本任务中写下以下脚本

 public void CheckConnectionString()
    {
        try
        {

            if (Dts.Connections["DynamicConnection"] != null)
            {
                ConnectionManager ConMGr = Dts.Connections["DynamicConnection"];
                ConMGr.AcquireConnection(null);
                Dts.Variables["ConnectionAvailable"].Value = true;
            }
        }
        catch (Exception ex)
        {
            Dts.Variables["ConnectionAvailable"].Value = false;
            Dts.Variables["ErrorDescription"].Value = ex.Message;
        }
        finally
        {
            Dts.TaskResult = (int)ScriptResults.Success;
        }
    }
