多步 OLE DB 操作产生错误。如果可能，请检查每个 OLE DB 状态值。
OleDbConnection MyConn = new OleDbConnection( "Provider=Microsoft.Jet.OLEDB.4.0; "+connectionString);
//MyConn.Open();
OleDbDataAdapter MyAdapter = new OleDbDataAdapter();
OleDbCommand MyCmd = new OleDbCommand(dlstr, MyConn);
MyAdapter.SelectCommand = MyCmd;
DataSet myDataSet = new DataSet();
int startdata = datasize * (Int32.Parse(pagenum) - 1);
MyAdapter.Fill(myDataSet, startdata, datasize, "result ");
以上是我的代码，我看了别的帖子，说这个错误是因为字段不够长，可是我没有理解，什么字段呀？
[解决办法]
dlstr打印出来
[解决办法]
"select para_cd,para_drpt,amt_vlu,para_typ,null as apply_dt from sysconf where para_typ= '83 ' and subcd_flg= '0 ' union select incentive_cd as para_cd,incentive_drpt as para_drpt,apply_point as amt_vlu, ' ' as para_typ,apply_dt from icapplypoint where ic_num= ' " + Session[ "ic_num "].ToString() + " ' ";
===================================================
上下的5个字段数据类型都兼容么？
para_cd,para_drpt,amt_vlu,para_typ,null as apply_dt
incentive_cd as para_cd,incentive_drpt as para_drpt,apply_point as amt_vlu, ' ' as para_typ,apply_dt
