播放框架：啓用oracle的數據庫演進

Question

播放框架中有一個bug。根據此錯誤，play_evolutions無法爲Oracle數據庫實例化。 如this question提到我使用以下腳本用於生成手動play_evolutions表：

CREATE TABLE play_evolutions 
(
    id Number(10,0) Not Null Enable, 
    hash VARCHAR2(255 Byte), 
    applied_at Timestamp Not Null, 
    apply_script clob, 
    revert_script clob, 
    state Varchar2(255), 
    last_problem clob, 
    CONSTRAINT play_evolutions_pk PRIMARY KEY (id) 
); 

與手動生成表，被施加的演變，但程序與以下堆棧跟蹤站：

的該原點問題是空的Downs部分在sql文件中。 我把它作爲問題#3033報告在遊戲框架工作社區
