用過DbVisualizer和Oracle SQL Developer，感受有不足之處，遂指望在EditPlus上打造一個簡易的SQL查詢器。java

1. Query.java, 用於在EditPlus上顯示結果spring

2. QueryVisual.java, 用於在GUI上顯示結果sql

3. EditPlus的用戶工具配置shell

3.1 tool_ui.iniapache

控制檯顯示oracle

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

GUI顯示

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
