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.

我在这里做错了什么？

如何解决下面的错误（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，您的光标或安全性（我使用集成安全性时遇到了同样的问题）。

将其更改为用户名/密码修复了我的问题。
