您也可以从更新指令码置放主索引键、索引和唯一的条件约束。
You can also drop primary keys, indexes, and unique constraints from the update script.
这正是两个诊断相冲突的地方：一个强调约束条件是唯一提振信心的方法；
This is where the two diagnoses collide. One emphasises conditions as the only way to confidence.
对于这一问题的目的，每个废品箱的容量是无限的，并且唯一的约束条件就是要通过移动瓶子使每个废品箱中都只有一种颜色的瓶子。
For the purposes of this problem, each bin has infinite capacity and the only constraint is moving the bottles so that each bin contains bottles of a single color.
当您尝试将资料产生器指派给具有唯一条件约束的资料行时，可用产生器的清单只会显示可以产生唯一值的产生器。
When you try to assign a data generator to a column that has a unique constraint, the list of available generators displays only generators that can produce unique values.
由于无法保证规则运算式产生器一定会产生唯一的值，所以您不能使用它来填满具有唯一条件约束的使用者定义型别资料行。
Because the Regular Expression generator is not guaranteed to produce unique values, you cannot use it to fill a user-defined type column that has a unique constraint.
