如何(TTL)使用Lodash在JavaScript中实现支持超时值的缓存？

_.memorize没有TTL功能。

我已经问过以下代码的问题:这是问题所在.

我有我在数据库查询(SQL Server)中使用的以下sql语法.

MERGE INTO table_with_team_and_goals AS target
USING (SELECT Team, SUM(headergoal + freekickgoal) AS goals FROM table_with_goals GROUP BY team) AS source
ON target.team=source.team
 WHEN MATCHED THEN 
        UPDATE SET goals = source.goals
    WHEN NOT MATCHED THEN   
        INSERT (Team, Goals)
        VALUES (source.team, source.goals);

我现在正在改为sql-server-ce(精简版).我可以发现,SQL Server Compact不支持sql支持的一些命令.(像marge into)

如何更改代码,它适用于SQL Server Compact.

感谢您的帮助!BK
