[英]Procedures in a database or in external jar in Derby
The document DerbySQLroutines explains that Derby procedures can be either stored in a database, using SQLJ.INSTALL_JAR, or kept in an external JAR file. DerbySQLroutines文档解释了Derby过程可以使用SQLJ.INSTALL_JAR存储在数据库中,也可以保留在外部JAR文件中。
What would be advantages of each approach? 每种方法的优点是什么?
Thank you. 谢谢。
If it's baked into the database, then the database is usable w/o extra jars. 如果将其烘焙到数据库中,则该数据库可以使用而无需额外的jar。 The disadvantage of that is that you'd have to go through the effort of getting the code into the database. 这样做的缺点是您必须努力将代码放入数据库。 It's sort of a pay now or pay later trade off. 现在有点付款,还是以后需要折衷。
