SERVER數據轉換ORACLE問題(1)

2013-11-13 22:18:57  來源: Oracle 

  大家做系統更新或者升級都可能要觸及到數據的轉換
對於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
而對於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!也是一種比較容易控制容易寫的方法!
首先你要在程序中建立連接(server的)

  string strCon=workstation id=XJ;packet size=;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_areagrean_bsp_build_p FROM bgxtpab_;
SqlConnection SqlCon = new SqlConnection(strCon);
SqlCommand SqlCmd = new SqlCommand(strTxtSqlCon);
SqlConOpen();
然後將你要讀的數據用dataReaderreader方法讀進來!

  SqlDataReader SqlDR = SqlCmdExecuteReader(CommandBehaviorCloseConnection);

  while(SqlDRRead())
{
try
{
OracleConOpen();
Bgxtpab_ bg = new Bgxtpab_();
//Doc d = new Doc();
//int i = ;
bgTworder_Code = SqlDRGetString()Trim();
bgStru_B = SqlDRIsDBNull()?:SqlDRGetString()Trim();
bgLayer_B = SqlDRIsDBNull()?:SqlDRGetInt();
bgArea_UB = SqlDRIsDBNull()?:SqlDRGetString();
bgArea_B = SqlDRIsDBNull()?:SqlDRGetString();
bgEast_B = SqlDRIsDBNull()?:SqlDRGetString()Trim();
bgSouth_B = SqlDRIsDBNull()?:SqlDRGetString()Trim();
bgWest_B = SqlDRIsDBNull()?:SqlDRGetString()Trim();
bgNorth_B = SqlDRIsDBNull()?:SqlDRGetString()Trim();

  //bgLayer_BD = SqlDRIsDBNull(++i)?F:SqlDRGetInt(i);
bgArea_SB = SqlDRIsDBNull()?:SqlDRGetString();
bgDensy_B = SqlDRIsDBNull()?:SqlDRGetString();
bgPark = SqlDRIsDBNull()?F:SqlDRGetFloat();
bgPark_Bike = SqlDRIsDBNull()?F:SqlDRGetFloat();
bgOTher_Area = SqlDRIsDBNull()?F:SqlDRGetFloat();
bgGrean_B = SqlDRIsDBNull()?F:SqlDRGetFloat();
bgSp_build_P = SqlDRIsDBNull()?:SqlDRGetString();
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!
