SERVER数据转换ORACLE问题(1) 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　大家做系统更新或者升级都可能要触及到数据的转换对于ORACLE中的数据转换可以用写存储过程来放之游标将你要的数据一条一条的转换而对于SERVER虽然你可以将它转换到ORACLE中（升级的方式）但有问题你会发现有的表是不可以直接转换的！所以我就用代码控制直接转换！也是一种比较容易控制容易写的方法！首先你要在程序中建立连接(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 order_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 bgxtpab _ ;SqlConnection SqlCon = new SqlConnection(strCon);SqlCommand SqlCmd = new SqlCommand(strTxt SqlCon);SqlCon Open();然后将你要读的数据用dataReader reader方法读进来！

　　SqlDataReader SqlDR = SqlCmd ExecuteReader(CommandBehavior CloseConnection);

　　while(SqlDR Read())tryOracleCon Open();Bgxtpab _ bg = new Bgxtpab _ ();//Doc d = new Doc();//int i = ;bg Tworder_Code = SqlDR GetString( ) Trim();bg Stru_B = SqlDR IsDBNull( )? :SqlDR GetString( ) Trim();bg Layer_B = SqlDR IsDBNull( )? :SqlDR GetInt ( );bg Area_UB = SqlDR IsDBNull( )? :SqlDR GetString( );bg Area_B = SqlDR IsDBNull( )? :SqlDR GetString( );bg East_B = SqlDR IsDBNull( )? :SqlDR GetString( ) Trim();bg South_B = SqlDR IsDBNull( )? :SqlDR GetString( ) Trim();bg West_B = SqlDR IsDBNull( )? :SqlDR GetString( ) Trim();bg North_B = SqlDR IsDBNull( )? :SqlDR GetString( ) Trim();

　　//bg Layer_BD = SqlDR IsDBNull(++i)? F:SqlDR GetInt (i);bg Area_SB = SqlDR IsDBNull( )? :SqlDR GetString( );bg Densy_B = SqlDR IsDBNull( )? :SqlDR GetString( );bg Park = SqlDR IsDBNull( )? F:SqlDR GetFloat( );bg Park_Bike = SqlDR IsDBNull( )? F:SqlDR GetFloat( );bg OTher_Area = SqlDR IsDBNull( )? F:SqlDR GetFloat( ); bg Grean_B = SqlDR IsDBNull( )? F:SqlDR GetFloat( ); bg Sp_build_P = SqlDR IsDBNull( )? :SqlDR GetString( ); 这样你就获得了你要的数据还要提到的是！你必须为你想读的表写个数据表的类！using System;

　　namespace ProjectBulid/// <summary>/// Bgxtpab _ 工程数据表/// </summary>public class Bgxtpab _ string order_code;//string project_b;string densy_b; string stru_b; int layer_b; string area_ub; string area_b; string usage_b; string east; string south; string west; string north; string area_sb;

　　float grean_b; float park; float park_bike; // decimal other_area_b; string sp_build_p; float other_area;

　　public Bgxtpab _ ()order_code = ;//project_b= ;stru_b = ;layer_b = ;area_ub = ;area_b = ;usage_b = ;east = ;south= ;west = ;north = ;//layer_db = ;area_sb = ;densy_b = ;grean_b = F;park = F;park_bike = F;sp_build_p = ;other_area = F;

　　public string Tworder_Codegetreturn order_code;setorder_code = value;public string Densy_Bgetreturn densy_b;setdensy_b = value;// public int Project_B// // get// // return project_b;// // set// // project_b = value;// // public string Stru_Bgetreturn stru_b;setstru_b = value;public int Layer_Bgetreturn layer_b;setlayer_b = value;public string Area_UBgetreturn area_ub;setarea_ub = value;public string Area_Bgetreturn area_b;setarea_b = value;public string Usage_Bgetreturn usage_b;setusage_b = value;public string East_Bgetreturn east;seteast = value;public string South_Bgetreturn south;setsouth = value;public string West_Bgetreturn west;setwest = value;public string North_Bgetreturn north;setnorth = value;// public int Layer_BD// // get// // return layer_db;// // set// // layer_db = value;// // public string Area_SBgetreturn area_sb;setarea_sb = value;public float Grean_Bgetreturn grean_b;setgrean_b = value;public float Parkgetreturn park;setpark = value;public float Park_Bikegetreturn park_bike;setpark_bike = value;
