Previously, you saw that the complexity of the generated job, and thus the number of stages composing the job, increases when you use columnar tests or functions with a rule.

从前，看到所生成任务的复杂性，组成任务的阶段数量，在使用具有柱状测试或者函数的规则时会增长。

To avoid too much complexity, DB2 imposes a simple rule: an UPDATE, DELETE or INSERT (data-change-operation) shall never happen in a join unless embedded in a correlated function.

为了避免太多的复杂性，DB 2强加了一条简单的规则：除非嵌入在相关的函数里面，否则UPDATE、DELETE或INSERT(数据更改操作)不应该出现在连接中。

However, the rule set is typically limited to rules and algorithms that are categorized with a degree of simple or medium complexity.

不过，规则集通常限于使用简单或中级复杂度进行分类的规则和算法。

The American Banker Association says its members fear that the rule is too broad and that its complexity will not only make it impossible for banks to comply but also affect their ability to compete globally.
