以Access为例
OleDbDataAdapter daDK = new OleDbDataAdapter(strSql, cn);
DataSet daDK.Fill(ds, "TableName");
DataView myDV = new DataView(ds.Tables["TableName"]);
myDV.RowFilter = "DKTime = #" + aryDK[3].ToString() + "#";
//如果没有重复记录
if (myDV.Count == 0)
{
while(myDV[i] != null)
{//遍历}
}
myDV[i]为过滤后的结果;
myDV.Table仍保存原来的整体数据. |
