大家做系統更新或者升級都可能要觸及到數據的轉換。對于Oracle中的數據轉換可以用寫存儲過程來放之游標，將你要的數據一條一條的轉換。而對于SERVER雖然你可以將它轉換到ORACLE中（升級的方式），但有問題你會發現有的表是不可以直接轉換的！所以我就用代碼控制直接轉換！也是一種比較輕易控制輕易寫的方法！首先你要在程序中建立連接(server的)string strCon='workstation id=XJ;packet size=4096;user id=sa;data source='automapautomap';persist security info=True;initial catalog=bgxtrmt;passWord=sa';string strTxt = 'SELECT tworder_code, stru_b, layer_b, area_ub, area_b, east, south, west, north, area_sb, densy_b, grean_b, park, park_bike, other_area,grean_b,sp_build_p FROM bgxtpab2_1';SqlConnection SqlCon = new SqlConnection(strCon);SqlCommand SqlCmd = new SqlCommand(strTxt,SqlCon);SqlCon.Open();然后將你要讀的數據用dataReader.reader方法讀進來！SqlDataReader SqlDR = SqlCmd.ExecuteReader(CommandBehavior.CloseConnection);while(SqlDR.Read()){try{OracleCon.Open();Bgxtpab2_1 bg = new Bgxtpab2_1();//Doc d = new Doc();//int i = -1;bg.Tworder_Code = SqlDR.GetString(0).Trim();bg.Stru_B = SqlDR.IsDBNull(1)?'':SqlDR.GetString(1).Trim();bg.Layer_B = SqlDR.IsDBNull(2)?0:SqlDR.GetInt32(2);bg.Area_UB = SqlDR.IsDBNull(3)?'':SqlDR.GetString(3);bg.Area_B = SqlDR.IsDBNull(4)?'':SqlDR.GetString(4);bg.East_B = SqlDR.IsDBNull(5)?'':SqlDR.GetString(5).Trim();bg.South_B = SqlDR.IsDBNull(6)?'':SqlDR.GetString(6).Trim();bg.West_B = SqlDR.IsDBNull(7)?'':SqlDR.GetString(7).Trim();bg.North_B = SqlDR.IsDBNull(8)?'':SqlDR.GetString(8).Trim();//bg.Layer_BD = SqlDR.IsDBNull(++i)?0.0F:SqlDR.GetInt32(i);bg.Area_SB = SqlDR.IsDBNull(9)?'':SqlDR.GetString(9);bg.Densy_B = SqlDR.IsDBNull(10)?'':SqlDR.GetString(10);bg.Park = SqlDR.IsDBNull(11)?0.0F:SqlDR.GetFloat(11);bg.Park_Bike = SqlDR.IsDBNull(12)?0.0F:SqlDR.GetFloat(12);bg.OTher_Area = SqlDR.IsDBNull(13)?0.0F:SqlDR.GetFloat(13); bg.Grean_B = SqlDR.IsDBNull(14)?0.0F:SqlDR.GetFloat(14); bg.Sp_build_P = SqlDR.IsDBNull(15)?'':SqlDR.GetString(15); 這樣你就獲得了你要的數據，還要提到的是！你必須為你想讀的表寫個數據表的類！using System;namespace ProjectBulid{/// <summary>/// Bgxtpab2_1工程數據表/// </summary>public class Bgxtpab2_1{string tworder_code;//string project_b;string densy_b;
