用Excel做DB，连接字符串如下：

ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\TEST.xls;Extended Properties='Excel 8.0;HDR=YES;'";

用OleDbDataAdapter对Excel进行数据插入，代码如下：

OleDbConnection oleConn = new OleDbConnection(ConnectionString);
oleConn.Open();

OleDbCommand oleCmd = new OleDbCommand("select * from " + tableName, oleConn);
OleDbDataAdapter da = new OleDbDataAdapter(oleCmd);

ds1 = new DataSet();
da.Fill(ds1, "[sheet1$]");

ds1.Tables[tableName].PrimaryKey = new DataColumn[] { ds1.Tables[tableName].Columns[0] };
DataRow row = ds1.Tables["[sheet1$]"].NewRow();
row[0] = 1;
row[1] = "Hello";
OleDbCommandBuilder myCommandBuilder = new OleDbCommandBuilder(da);     
da.InsertCommand = myCommandBuilder.GetInsertCommand();

da.Update(ds1,tableName); //提示“Syntax error in INSERT INTO statement” 

请教大侠，问题到底出在哪里，郁闷了许久，google了也没找出问题。

ps:也设了主键，应该不是主键问题
