使用OleDbCommandBuilder时访问SQL语法错误

我将使用C＃中的OleDbDataAdapter在Access数据库中插入数据但是我在INSERT INTO命令中出现错误消息语法错误

BackgroundWorker worker = new BackgroundWorker(); OleDbDataAdapter dbAdapter new OleDbDataAdapter(); OleDbConnection dbConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\\PMS.mdb"); worker = new BackgroundWorker(); worker.WorkerReportsProgress = true; worker.DoWork += InsertJob; worker.ProgressChanged += InsertJobCompleted; worker.RunWorkerAsync(args); 

而InsertJob函数是：

 private void InsertJob(object sender, DoWorkEventArgs e) { var args = (InsertJobArgs)e.Argument; try { dbAdapter.SelectCommand = new OleDbCommand("SELECT * FROM Sheet", dbConnection); dbAdapter.Fill(args.DataTable); var builder = new OleDbCommandBuilder(dbAdapter); var row = args.DataTable.NewRow(); row["UserName"] = args.Entry.UserName; row["Password"] = args.Entry.Password; args.DataTable.Rows.Add(row); dbAdapter.InsertCommand = builder.GetInsertCommand(); dbAdapter.Update(args.DataTable); builder.Dispose(); } catch (Exception ex) { args.Exception = ex; worker.ReportProgress(0, args); return; } worker.ReportProgress(100, args); } 

我在线收到错误： dbAdapter.Update(args.DataTable);

我尝试使用visual studio调试它，发现所有InsertCommand参数值都为null

在调用dbAdapter.Update(args.DataTable);之前，我试图通过此代码手动插入它dbAdapter.Update(args.DataTable);

 dbAdapter.InsertCommand.Parameters[0].Value = args.Entry.UserName; dbAdapter.InsertCommand.Parameters[1].Value = args.Entry.Password; 

Answer 1

试试这个：

紧接着就行了

 var builder = new OleDbCommandBuilder(dbAdapter); 

添加两行

 builder.QuotePrefix = "["; builder.QuoteSuffix = "]"; 

这将告诉OleDbCommandBuilder将表和列名称包装在方括号中，生成一个INSERT命令

 INSERT INTO [TableName] ... 

而不是默认forms

 INSERT INTO TableName ... 

如果任何表或列名称包含空格或“有趣”字符，或者它们恰好是Access SQL中的保留字，则必须使用方括号。 （在您的情况下，我怀疑您的表有一个名为[Password]的列，而PASSWORD是Access SQL中的保留字。）
