You can also use the system catalog views to retrieve information about NOT NULL, unique, primary key, foreign key, and table check constraints. For example.
也可以使用系统编目视图来检索关于NOT NULL、惟一、主键、外键和表检查约束的信息。
In this case, the check constraints defined on nicknames canada.items and usa.items will allow the rewrite phase to eliminate one of the UNION all branches.
在这里，定义在昵称canada . items和us a . items上的检查约束将允许重写阶段删除其中一个UNION ALL分支。
Also check that changing the value of unbounded constraints won't make any difference to the solution, as expected.
还要检查修改无边界约束的值不会对解答造成任何变化，这正是我们期望的。
A number of constraints are defined by the W3C XML schema specification that are time consuming and memory intensive to check.
W3CXML模式规范中定义的一些约束，检查起来非常耗时而且需要较大的内存空间。
Check constraints are constraints on table columns that are used to restrict the user to a particular check condition.
检查限制是表的列上的限制，用于将用户限制到特定的检查条件。
Multiple constraint technologies typically are required to comprehensively declare the constraints, and to check information at run-time before it is dispatched to the actual service logic.
为了完整地声明约束，并且在将其指派给实际的服务逻辑之前检查信息，通常需要多种约束技术。
For our second strategy (one table per class hierarchy), you'll have to define your integrity using check constraints.
对于第二个策略(每个类层次结构一个表)，您必须用检测约束定义您自己的完整性。
While you are developing your schema grammar, you should set this feature to true so that Xerces2 will check all the constraints necessary to determine if your schema is valid.
如果您在开发自己的模式语法，应该将该特性设为true，让Xerces2检查所有必要的约束，确定模式是否有效。
Be sure to check out the Grails documentation for the complete list of available constraints.
请查看Grails文档以获得全部可用的约束。
The Check constraints view allows you to create table check constraints for the table.
Check constraints视图允许为表创建表检查约束。
Similar to the before trigger, the IS VALIDATED ACCORDING TO XMLSCHEMA clause can be used in the check constraints to enforce the validation.
与beforetrigger类似，可以在检查约束中使用ISVALIDATEDACCORDINGTO XMLSCHEMA 子句来加强验证。
Optionally, CHECK constraints can be defined on the pdbxml table to ensure that the four-character PDB identifier conforms to the PDB standard.
