Question

我想通过播放框架演化脚本为Postgres DB创建以下触发器，如果我在sql ID-e工具中运行它可以正常但是当我尝试通过播放应用程序中的evolution / migration脚本运行它时它返回一个错误：

 CREATE OR REPLACE FUNCTION mark_processed()
  RETURNS trigger AS
  $BODY$
  BEGIN
    IF NEW.status <> OLD.status and NEW.status = 'FT' THEN
      update "match" set processed = true;
    END IF;
    RETURN NEW;
  END;
  $BODY$
  LANGUAGE plpgsql;

  CREATE TRIGGER on_fultime_trigger
  AFTER UPDATE
    ON "match"
  FOR EACH ROW
  EXECUTE PROCEDURE mark_processed();

错误：

e出现以下错误：错误：未终止的美元引用字符串at 或者附近＆＃34; $ BODY $ BEGIN如果NEW.status＆lt;＆gt; OLD.status和NEW.status = ＆＃39; FT＆＃39;然后更新＆＃34;匹配＆＃34; set processed = true＆＃34;位置：64 [错误：0， SQLSTATE：42601]，在尝试运行此SQL脚本时：

堆栈跟踪：

这是游戏进化的错误。你必须加倍所有“;”......
所以你的代码是：

  CREATE OR REPLACE FUNCTION mark_processed()
  RETURNS trigger AS
  $BODY$
  BEGIN
  IF NEW.status <> OLD.status and NEW.status = 'FT' THEN
  update "match" set processed = true;;
  END IF;;
  RETURN NEW;;
  END;;
  $BODY$
  LANGUAGE plpgsql;;

  CREATE TRIGGER on_fultime_trigger
  AFTER UPDATE
    ON "match"
  FOR EACH ROW
  EXECUTE PROCEDURE mark_processed();;

无法在Play框架演进中执行创建postgres功能
