sCommand="select a from b";
sCommand1="select c from d";
OleDbDataAdapter objadp = new OleDbDataAdapter (sCommand,necConn);
OleDbDataAdapter objadp1 = new OleDbDataAdapter (sCommand1,necConn);
DataSet Resultset = new DataSet();
objadp.Fill(Resultset,"meNec");
objadp1.Fill(Resultset,"meNec1");

在這裡,有时会莫名其妙的报System.Data.OleDb.OleDbException: Unspecified error: E_FAIL(0x80004005) at System.Data.OleDb.OleDbCommand.ProcessResults(Int32 hr) at System.Data.OleDb.OleDbCommand.InitializeCommand(CommandBehavior behavior, Boolean throwifnotsupported) at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.OleDb.OleDbCommand.System.Data.IDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(Object data, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable)

最好用一个DataAdapter分两次填充!
