不说了直接上代码:
try{
String str = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='" + address + "'";
con = new OleDbConnection(str);
con.Open();
OleDbCommand cmd = con.CreateCommand();
//获得数据
OleDbDataAdapter dagroup = new OleDbDataAdapter("select DATA_NAME from BL_BUILD group by DATA_NAME ", con);
DataSet dsgroup = new DataSet();
dagroup.Fill(dsgroup, "ddgroup");
//执行sql 语句
cmd.CommandText = item;
int num = cmd.ExecuteNonQuery();
con.Close();
}
catch (Exception ex)
{
con.Close();
con.Dispose();
throw ex;
}
