As shown in Figure 16, the bulk load operation results in two of the sample records being sent to the reject link because they violate the unique primary key constraint.
如图16所示，两个示例记录中的批量加载操作结果被发送给拒绝链接，因为它们违反唯一的主键约束。
If you click on the System.out link at the bottom of the HTML report, you can see that three of the String fields (name, login, and password) all threw the nullable constraint violation.
如果单击HTML报告底部的System. out链接，可以看到3个String字段(name、login和password)都抛出了nullable约束违规错误。
For example, when a constraint is violated, you might want to provide a link from the informative message to the field that is primarily responsible for the violation.
例如，当违反条件时，可能希望在信息性消息中提供违反条件的字段的链接。
Systems are analogous to chains. Each system has a "weakest link" (constraint) that ultimately limits the success of the entire system.
系统类似于链条，每个系统都有最弱环节(制约)最终限制整个系统的成功。
The adjustment of pivot position of the middle link in planar 6-link Watt-type linkage is classified. The corresponding constraint equations of each mechanism are presented.
对平面六杆瓦特型机构中间杆固定铰链中心位置的调节进行了分类，并给出了约束方程。
