多步OLE DB操作生成错误
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 System.Data.OleDb.OleDbConnectionInternal..ctor(OleDbConnectionString constr, OleDbConnection connection) at System.Data.OleDb.OleDbConnectionFactory.CreateConnection(DbConnectionOptions options, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection(DbConnection owningConnection, DbConnectionPoolGroup poolGroup) at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.OleDb.OleDbConnection.Open() at System.Data.Common.DbDataAdapter.QuietOpen(IDbConnection connection, ConnectionState& originalState) at System.Data.Common.DbDataAdapter.FillSchemaInternal(DataSet dataset, DataTable datatable, SchemaType schemaType, IDbCommand command, String srcTable, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillSchema(DataSet dataSet, SchemaType schemaType, IDbCommand command, String srcTable, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillSchema(DataSet dataSet, SchemaType schemaType) at IMS.DF2.IMSCubeGenerator.IMSCube.AddTableToDatasourceView(table objTable) in C:\DIUP\DF2\IMSCubeGenerator\IMSCube.cs:line 902
我在这做错了什么？
如何找到下面的错误（检查每个OLE DB状态值）？
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）。
将此更改为用户名/密码修复了我的问题。
