oracle数据库编程一般原则

翻译自Tom Kyte：

1.You should do it in a single SQL statement if at all possible.
2.If you cannot do it in a single SQL Statement, then do it in PL/SQL.
3.If you cannot do it in PL/SQL, try a Java Stored Procedure.
4.If you cannot do it in Java, do it in a C external procedure.
5.If you cannot do it in a C external routine, you might want to seriously think about why it is you need to do it…
1.我们应该尽量使用单个SQL语句来实现应用需求
2.如果单个SQL无法实现，考虑使用PL/SQL来实现
3.如果PL/SQL无法实现，接下来可以尝试使用Java存储过程来实现
4.如果Java过程也不行，尝试使用C的外部存储过程来解决
5.如果以上都不能实现，那么你应该认真考虑你为什么要实现这个需求...
