问题 I'm hoping somebody could provide me with some fresh eyes on my vb script. The main purpose of this script is to execute a stored procedure using some parameters. The error I get is 'Expected end of statement' I haven't done much VB scripting but from what I have found so far - this error has been down to some kind of syntax issue. I've looked over this script for many hours and can't see anything obvious. I can only assume it's down to the declaration of adArray (which doesn't look right in

问题 I am running a simple FillSchema from a Netezza data source dss = new DataSet(); ad = new OleDbDataAdapter(cmd); ad.SelectCommand = new OleDbCommand("SELECT * FROM " + objTable.name); ad.SelectCommand.Connection = cn; ad.FillSchema(dss, SchemaType.Source); I get the following error: 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

问题 I'm trying to implement a password change feature but it doesn't seem to want to work. private void button3_Click(object sender, EventArgs e) { using (OleDbConnection con = new OleDbConnection(@"Provider = Microsoft.ACE.OLEDB.12.0; Data Source = C:\Users\User\Desktop\esoft\gym\gym\bin\Debug\Clients.accdb")) { DataTable dt = new DataTable(); con.Open(); errorProvider1.Clear(); if (dt.Rows[0][0].ToString() == "1") { if (textBox3.Text == textBox4.Text) { OleDbDataAdapter da = new

问题 I'm doing a little bit of work on a horrid piece of software built by Bangalores best. It's written in mostly classic ASP/VbScript, but "ported" to ASP.NET, though most of the code is classic ASP style in the ASPX pages :( I'm getting this message when it tries to connect to my local database: Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done. Line 38: MasterConn = New ADODB.Connection() Line 39: MasterConn.connectiontimeout =

问题 Question: I am working with existing commercial MS Visual Foxpro application, and need to extract data from the database directly using a c# application. Unfortunately, not all of the tables are stored in the same database, some of the records are stored in a database broken down by year. How do I create a query against these two databases using a single join? I am using Microsoft's OLE DB Provider for Visual FoxPro 9.0 (SP2) More Detail: Essentially, the customer information is stored in one

问题 This is a failed response to this article: Sybase, VB and ADO I just did a VB6 project connecting to a legacy ASA 7 database. After failing to use ASAProv OLEDB provider altogether (for one reason or another) and much research, here is the connect string for OLEDB Provider for ODBC shim for a DSN-less ODBC driver connection: Provider=MSDASQL.1;Driver={Adaptive Server Anywhere 7.0};CommLinks=TCPIP,SharedMemory;EngineName=<database_name>;UID=DBA;PWD=SQL where <database_name> is the instance

问题 I have a website which uses OLEDB to connect to MS SQL Analysis Server Services. I use C++ to call OLEDB APIs, and build it as DLL, which is loaded into IIS and called by my website. I can successfully connect to data source by calling OLEB APIs if I run C++ module locally, but my website fails to connect to data source in IIS. The error message is "An error was encountered in the transport layer". According to MSDN documents, it's an authentication problem. But anonymous user is allowed in

问题 I' m trying to export xlsx file with these codes: DataTable dataTable= new DataTable(tableName); OleDbDataAdapter adapter = new OleDbDataAdapter(select, accessConnection); adapter.FillSchema(dataTable, SchemaType.Source); foreach (DataRow result in dtResult.Rows) { DataRow newRow = dataTable.NewRow(); foreach (DataRow drAssign in dtAssignment.Rows) { newRow[drAssign["Destination"].ToString()] = result[drAssign["Source"].ToString()]; } dataTable.Rows.Add(newRow); } adapter.Update(dataTable);

问题 In SQL you can use SELECT * FROM INFORMATION_SCHEMA.TABLES etc to get information about the database structure. I need to know how to achieve the same thing for an Access database. 回答1: The equivalent operation can be accomplished using OleDbConnection.GetOleDbSchemaTable() method. see http://support.microsoft.com/kb/309488 for more information 回答2: In OLEDB it can be accessed as DBSCHEMA_TABLES. Following C++ code demonstrates the retrieval of the tables information from an OLEDB provider:

问题 In a production environment, I found that port 1433 must be explicitly specified for a "Microsft OLE DB Provider for SQL Server" UDL. Like this: Provider=SQLOLEDB.1;User ID=USER;Data Source=IP,1433 Without the port specified, the error is: Test connection failed because of an error in initializing provider. [DBNETLIB][ConnectionOpen (Invalid Instance()).]Invalid connection. Same environment, but SQL Native Client 10.1, does not require 1433 explicitly specified: Provider=SQLNCLI10.1
