EditPlus + JavaFx 编写SQL简易查询器

用过DbVisualizer和Oracle SQL Developer，感觉有不足之处，遂期望在EditPlus上打造一个简易的SQL查询器。

1. Query.java, 用于在EditPlus上显示结果

2. QueryVisual.java, 用于在GUI上显示结果

3. EditPlus的用户工具配置

3.1 tool_ui.ini

控制台显示

Text=run SQL in Console
Command=C:\Users\user\Desktop\Forest\command\run SQL.bat
Argument=$(Prompt) "$(CurSel)"
InitDir=$(FileDir)

GUI显示

Text=run SQL in GUI
Command=C:\Users\user\Desktop\Forest\command\javafx.bat
Argument=$(Prompt) "$(CurSel)"
InitDir=$(FileDir)

4. run SQL.bat

"C:\Program Files\Java\jre7\bin\java.exe" -cp .;"C:\Users\user\workspace\SQL Query\bin";C:\Users\user\workspace\common-lib\ojdbc14.jar;C:\Users\user\workspace\common-lib\sqljdbc4.jar;C:/Users/user/Desktop/Forest/spring-framework-2.5.6/lib/jakarta-commons/commons-beanutils.jar;C:/Users/user/Desktop/Forest/spring-framework-2.5.6/lib/jakarta-commons/commons-lang.jar forest.Query %1 %2

5. javafx.bat

"C:\Program Files\Java\jre7\bin\java.exe" -cp C:\Users\user\Downloads\javafx-sdk2.0-beta\rt\lib\jfxrt.jar;.;"C:\Users\user\workspace\SQL Query\bin";C:\Users\user\workspace\common-lib\ojdbc14.jar;C:\Users\user\workspace\common-lib\sqljdbc4.jar;C:/Users/user/Desktop/Forest/spring-framework-2.5.6/lib/jakarta-commons/commons-beanutils.jar;C:/Users/user/Desktop/Forest/spring-framework-2.5.6/lib/jakarta-commons/commons-lang.jar forest.QueryVisual %1 "gui" %2
