使用MyGeneration自动生成代码工具获取所有ORACLE数据库的数据库名数据表命列名称的具体操作步骤如下: 一、设置MyGeration的Default Settings中的数据库链接字符串Provider=OraOLEDB.Oracle.1;Password=myPassword;Persist Security Info=True;User ID=myID

使用MyGeneration自动生成代码工具获取所有ORACLE数据库的数据库名数据表命列名称的具体操作步骤如下:
一、设置MyGeration的Default Settings中的数据库链接字符串Provider=OraOLEDB.Oracle.1;Password=myPassword;Persist Security Info=True;User ID=myID;Data Source=myDataSource
二、复制下面代码到Interface Code选项卡的窗体中

public class GeneratedGui : DotNetScriptGui
{
 public GeneratedGui(ZeusContext context) : base(context) {}

 //-----------------------------------------
 // The User Interface Entry Point
 //-----------------------------------------
 public override void Setup()
 {
  // ** UNCOMMENT CODE BELOW TO SEE UI **

  //ui.Width  = 100;
  //ui.Height = 100;
  //GuiLabel lblDemo = ui.AddLabel("lblDemo", "Demo", "Demo Tooltip");
  //ui.ShowGui = true;
  
  //GuiLabel lblPath;
  //GuiTextBox txtNamespace;
  GuiComboBox cmbDatabase;
  GuiComboBox cmbTable;
  GuiComboBox cmbColumn;
 
  ui.Title = "读取所有数据表";
  ui.Width  = 450;
  ui.Height = 500;
  ui.BackColor = "wheat";
  ui.ShowGui = true;
  //添加窗体控件
  ui.AddLabel("lblPath","输出路径: ","Select the output path."); 
  string sOutputPath = "";   
  if( input.Contains("defaultOutputPath"))
  {
   sOutputPath = input["defaultOutputPath"].ToString();
  }
  //输出文件保存路径
  ui.AddTextBox("txtPath", sOutputPath, "Select the Output Path.");
  ui.AddFilePicker("btnPath", "选择路径", "Select the Output Path.", "txtPath", true);
  //程序命名空间
  ui.AddLabel("lblNamespace", "命名空间: ",  "Provide your objects namespace.");
  ui.AddTextBox("txtNamespace", "ZTE.TMobileUpdate", "Provide your objects namespace."); 
  //数据库下拉框
  ui.AddLabel("lblDatabases", "数据库选择:", "Select a database in the dropdown below.");
  cmbDatabase=ui.AddComboBox("cmbDatabase", "Select a database.");
  setupDatabaseDropdown(cmbDatabase);
  cmbDatabase.AttachEvent("onchange","cmbDatabase_onchange");
  //数据表选择
  ui.AddLabel("lblTables", "数据表选择:", "Select tables from the listbox below.");
  cmbTable = ui.AddComboBox("cmbTable", "Select tables:");
  setupTablesDropdown(cmbDatabase,cmbTable);
  cmbTable.AttachEvent("onchange","cmbTable_onchange");
  //视图选择
  ui.AddLabel("lblColumns", "字段选择:", "Select columns from the listbox below.");
  cmbColumn = ui.AddComboBox("cmbColumn", "Select columns:");
  
 }
 
 public void setupDatabaseDropdown( GuiComboBox Databases )
 {
  try
  { 
   if( MyMeta.IsConnected )
   {
    Databases.BindData( MyMeta.Databases );
    //判断数据库列表是否为空
    if( MyMeta.DefaultDatabase != null )
    {
     Databases.SelectedValue = MyMeta.DefaultDatabase.Alias;
     bindTables( Databases.SelectedValue );
    }
   }
  }
  catch
  {
  }
 }
 public void setupTablesDropdown(GuiComboBox Databases,GuiComboBox Tables)
 {
  try
  { 
   if( MyMeta.IsConnected )
   {
    //判断数据表列表是否为空
    if((Databases.SelectedValue != null)&&(Tables.SelectedValue != null))
    {
     bindColumns(Databases.SelectedValue,Tables.SelectedValue);
    }    
   }
  }
  catch
  {
  }
 }
 
 //数据库切换事件
 public void cmbDatabase_onchange( GuiComboBox control )
 {
  GuiComboBox cmbDatabases = ui["cmbDatabase"] as GuiComboBox; 
  bindTables( cmbDatabases.SelectedText );
 }
 //数据表切换事件
 public void cmbTable_onchange( GuiComboBox control )
 {
  GuiComboBox cmbDatabases = ui["cmbDatabase"] as GuiComboBox;
  GuiComboBox cmbTable = ui["cmbTable"] as GuiComboBox; 
  bindColumns(cmbDatabases.SelectedText, cmbTable.SelectedText);
 }
 
 public void bindTables( string sDatabase )
 { 
  try
  { 
   IDatabase db = MyMeta.Databases[sDatabase];
   GuiComboBox cmbTable = ui["cmbTable"] as GuiComboBox;
   cmbTable.BindData( db.Tables );
  }
  catch
  {
  }
 }
 
 public void bindColumns( string sDatabase,string sTable )
 { 
  try
  { 
   IDatabase db = MyMeta.Databases[sDatabase];
   ITable objTable=db.Tables[sTable];
   GuiComboBox cmbColumn = ui["cmbColumn"] as GuiComboBox;
   cmbColumn.BindData( objTable.Columns );
  }
  catch
  {
  }
 } 
}
三、复制下面代码到Template Code选项卡的窗体中
public class GeneratedTemplate : DotNetScriptTemplate
{
 public GeneratedTemplate(ZeusContext context) : base(context) {}

 //---------------------------------------------------
 // Render() is where you want to write your logic   
 //---------------------------------------------------
 public override void Render()
 {   
  if(context.Objects.ContainsKey("DnpUtils"))
  {
   DnpUtils.SaveInputToCache(context);
  }  
  string strFilenameBase = input["txtPath"].ToString();
  string strNamespace = input["txtNamespace"].ToString();
  string strDatabaseName  = input["cmbDatabase"].ToString();
  string strTableName  = input["cmbTable"].ToString();
  string strColumnName  = input["cmbColumn"].ToString();
  
  output.writeln("输出文件路径:"+strFilenameBase);
  output.writeln("命名空间名称:"+strNamespace);
  output.writeln("当前数据库名称:"+strDatabaseName);
  output.writeln("当前数据表名称:"+strTableName);
  output.writeln("当前选择列名称:"+strColumnName);
  GetAllDataBaseName();    
 }
 //输出所有的数据库名称
 private void GetAllDataBaseName()
 {
  foreach( IDatabase d in MyMeta.Databases )
   {
    GetAllTablesName(d.Alias);
   }  
 }
 //输出所有的数据表名称
 private void GetAllTablesName(string sDatabase)
 {  
  IDatabase objDatabase = MyMeta.Databases[sDatabase];
  output.writeln("当前数据库:"+sDatabase+"共有数据表总数:"+objDatabase.Tables.Count);
  foreach( ITable t in objDatabase.Tables )
   {
    GetAllColumnsName(sDatabase,t.Alias);
   }
 }
 private void GetAllColumnsName(string sDatabase,string sTable)
 {
  IDatabase objDatabase = MyMeta.Databases[sDatabase];
  ITable objTable=objDatabase.Tables[sTable];
  output.writeln("当前数据表:"+sTable+"共有数据列总数:"+objTable.Columns.Count);
  foreach( IColumn c in objTable.Columns )
   {
    if( c.IsInPrimaryKey )
    {
     output.writeln("主键名称:"+c.Alias);
    }
    else
    {
     output.writeln("普通列名:"+c.Alias);
    }
   }
 }

}
%>
四、点菜单上的运行箭头按钮,在Output选项卡的窗体中显示所有结果
