c# - 多步 OLE DB 操作产生的错误

Question

我正在从 Netezza 数据源运行一个简单的 FillSchema

dss = new DataSet();
ad = new OleDbDataAdapter(cmd);
ad.SelectCommand = new OleDbCommand("SELECT * FROM " + objTable.name);
ad.SelectCommand.Connection = cn;
ad.FillSchema(dss, SchemaType.Source);

我收到以下错误:

System.Data.OleDb.OleDbException: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.
   at System.Data.OleDb.OleDbServicesWrapper.GetDataSource(OleDbConnectionString constr, DataSourceWrapper& datasrcWrapper)

   at IMS.DF2.IMSCubeGenerator.IMSCube.AddTableToDatasourceView(table objTable) in C:\DIUP\DF2\IMSCubeGenerator\IMSCube.cs:line 902

我在这里做错了什么？

我怎样才能找到下面的错误(检查每个 OLE DB 状态值)？

Answer 1

你的连接字符串是什么？

它将是您的驱动程序、光标或安全性(我在使用集成安全性时遇到了同样的问题)。

将其更改为用户名/密码解决了我的问题。
