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="automap/automap";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！

}下面要做的就是往oracle中寫你要的數據了！
建立連接:
string OracleString = "user id=constrUCt;data source=oracle;password=rose";
string OracleText = “在這里寫你要插入的sql語句“
OracleConnection OracleCon = new OracleConnection(OracleString);
OracleCommand OracleCmd = new OracleCommand(OracleText,OracleCon);然后幫oracle表中構造字段:
#region BuildingEnnginger參數設置
OracleCmd.Parameters.Clear();
OracleCmd.Parameters.Add(":DOCID",OracleType.Int32);
OracleCmd.Parameters.Add(":CONSTRUCTDENSITY",OracleType.Float);
OracleCmd.Parameters.Add(":BUILDINGTOTALHEIGHT",OracleType.Float);
OracleCmd.Parameters.Add(":GREENAREA",OracleType.Float);
OracleCmd.Parameters.Add(":PARKINGAREA",OracleType.Float);
OracleCmd.Parameters.Add(":MINipARKINGAREA",OracleType.Float);
OracleCmd.Parameters.Add(":OTHERESTABLISHMENTAREA",OracleType.Float);
OracleCmd.Parameters.Add(":CUBAGERATE",OracleType.Float);
OracleCmd.Parameters.Add(":LANDUSAGE",OracleType.Int32);
OracleCmd.Parameters.Add(":AGROUNDFLOORCOUNT",OracleType.Int32);
OracleCmd.Parameters.Add(":UNDERGROUNDFLOORCOUNT",OracleType.Int32);

OracleCmd.Parameters.Add(":ORIGINALFLOORAMOUNT",OracleType.Int32);
OracleCmd.Parameters.Add(":ORIGINALEAST",OracleType.VarChar);
OracleCmd.Parameters.Add(":ORIGINALWEST",OracleType.VarChar);

OracleCmd.Parameters.Add(":ORIGINALNORTH",OracleType.VarChar);
OracleCmd.Parameters.Add(":BUILDINGMEMO",OracleType.VarChar);
OracleCmd.Parameters.Add(":ALLPLINTHAREA",OracleType.Float);
OracleCmd.Parameters.Add(":DESIGNAGROUNDFLOOR",OracleType.Int32);
OracleCmd.Parameters.Add(":DESIGNUNDERGROUNDFLOOR",OracleType.Int32);
OracleCmd.Parameters.Add(":DESIGNSPECIALTIESFLOOR",OracleType.VarChar);#endregion
#region 參數附值
OracleCmd.Parameters[":DOCID"].Value = SelectInsert(bg.Tworder_Code).ToString(); //這里是傳參數進去獲得想得到的數據
后面的就是你俯值的具體代碼了；（ 如bg.Densy_B）
if(bg.Densy_B.ToString() == "")
OracleCmd.Parameters[":CONSTRUCTDENSITY"].Value = DBNull.Value;
else
OracleCmd.Parameters[":CONSTRUCTDENSITY"].Value = bg.Densy_B;
OracleCmd.Parameters[":BUILDINGTOTALHEIGHT"].Value = DBNull.Value;
if(bg.Grean_B.ToString() == "")
OracleCmd.Parameters[":GREENAREA"].Value = DBNull.Value;
else
OracleCmd.Parameters[":GREENAREA"].Value = bg.Grean_B;
if(bg.Park.ToString() =="")
OracleCmd.Parameters[":PARKINGAREA"].Value = DBNull.Value;
else
OracleCmd.Parameters[":PARKINGAREA"].Value = bg.Park;
if(bg.Park_Bike.ToString() =="")
OracleCmd.Parameters[":MINIPARKINGAREA"].Value = DBNull.Value;
else
OracleCmd.Parameters[":MINIPARKINGAREA"].Value = bg.Park_Bike;
if(bg.OTher_Area.ToString() == "")
OracleCmd.Parameters[":OTHERESTABLISHMENTAREA"].Value = DBNull.Value;
else
OracleCmd.Parameters[":OTHERESTABLISHMENTAREA"].Value = bg.OTher_Area;
OracleCmd.Parameters[":CUBAGERATE"].Value = DBNull.Value;
OracleCmd.Parameters[":LANDUSAGE"].Value = DBNull.Value; //詞典
if(bg.Layer_B.ToString() == "")
OracleCmd.Parameters[":AGROUNDFLOORCOUNT"].Value = DBNull.Value;
else
OracleCmd.Parameters[":AGROUNDFLOORCOUNT"].Value = bg.Layer_B;OracleCmd.Parameters[":UNDERGROUNDFLOORCOUNT"].Value = DBNull.Value;
if(bg.East_B == "")
OracleCmd.Parameters[":EAST"].Value = DBNull.Value;
else
OracleCmd.Parameters[":EAST"].Value = bg.East_B;

if(bg.Area_UB == "")
OracleCmd.Parameters[":ORIGINALUSELANDAREA"].Value = DBNull.Value;
else

if(bg.Area_B == "")
OracleCmd.Parameters[":ORIGINALBUILDINGAREA"].Value = DBNull.Value;
else

if(bg.Stru_B == "")
OracleCmd.Parameters[":ORIGINALSTRUCTURETYPE"].Value = DBNull.Value;
else
OracleCmd.Parameters[":ORIGINALSTRUCTURETYPE"].Value = bg.Stru_B;
OracleCmd.Parameters[":ORIGINALFLOORAMOUNT"].Value = DBNull.Value;
OracleCmd.Parameters[":ORIGINALEAST"].Value = DBNull.Value;
OracleCmd.Parameters[":ORIGINALWEST"].Value = DBNull.Value;
OracleCmd.Parameters[":ORIGINALSOUTH"].Value = DBNull.Value;

OracleCmd.Parameters[":DESIGNAGROUNDFLOOR"].Value = DBNull.Value;
OracleCmd.Parameters[":DESIGNUNDERGROUNDFLOOR"].Value = DBNull.Value;
OracleCmd.Parameters[":DESIGNSPECIALTIESFLOOR"].Value = DBNull.Value;
最后要講到的就是寫函數來獲得你要從其他表中得到的數據!
public int SelectInsert(string tm)
{
int id = 0;
try
{string OracleString = "user id=construct;data source=oracle;password=rose";
OracleConnection OracleConn = new OracleConnection(OracleString);
OracleConn.Open();
//string temp;
string str = "SELECT ID FROM document.DOC WHERE TM = '" +tm.Trim() +"'"; OracleCommand OracleComd = new OracleCommand(str,OracleConn);
Object obj = OracleComd.ExecuteScalar();
if(obj != null)
{
id = Convert.ToInt32(obj);
}
//id = int.Parse(OracleComd.ExecuteOracleScalar().ToString());
#region
// Object obj = OracleComd.ExecuteReader();
// if(obj!=null)
// {
// id = Convert.ToInt32(obj);
// }
// if(obj >1)
// {
// id = Convert.ToInt32(obj) + 100;
// }
#endregion
OracleConn.Close();
OracleConn.Dispose();
//DR1.Dispose();}
catch(Exception ex)
{
Debug.Fail(ex.Message +"-"+ ex.StackTrace);
}
return id;
}
這里隨你怎么寫！無論是要什么值只要在其他表中有關聯的字段，就可以獲得你想要的數據！
程序寫到這里也差不多完了。這是我想到的一種方法！
大家有什么好方法共享寫大家一起學習！
多指教?。?！
