目前的CTP 1仅支持表、索引和约束。
如果在表的xml列上存在XML验证检查约束，在手动更新或者通过触发器更新之前，用户可能需要验证新的xml值。
If an XML validation check constraint exists on the XML column of the table, the user may need to validate the new XML value before the update either manually or by creating a trigger.

SQL Azure is based on the relational database model, complete with constraints, transactions, temporary tables, and stored procedures.
还可以创建表、视图、用户、约束与索引。
It can also be used to create tables, views, users, constraints and indexes.
tabconst为每个唯一性(U)、主键(p)、外键(f)或者表检查(K)约束保持一个行db2select constname,tabname,typefrom syscat . tabconst。
Syscat.tabconst Contains a row for each unique (u), primary key (p), foreign key (f), or table check (k) constraint db2 select constname, tabname, type from syscat.tabconst.
checks为每个表检查约束保持一个行db2select constname,tabname,textfrom syscat . checks。
Syscat.checks Contains a row for each table check constraint db2 select constname, tabname, text from syscat.checks.
Checkconstraints视图—允许添加表及其列的检查约束。
Check constraints view a "Allows adding check constraints for a table and its columns."
COLCHECKS为表检查约束所引用的每个列保持一个行db2select constname,tabname,colname,usagefrom syscat.colchecks
SYSCAT.COLCHECKS Contains a row for each column that is referenced by a table check constraint db2 select constname, tabname, colname, usage from syscat.colchecks

Creating constraints on tables (for example, RI, informational, unique).
如果远程表在数据上有检查约束，那么可以使用信息检查约束将这些约束传递到联邦服务器。
If the remote tables have restrictions on the data such as check constraints, you can convey these restrictions to the federated server using informational check constraints.
我们建立一定的时间表、约束条件、检查点，和通信程序，但我们将细节留给第三方。
We establish certain timetables, constraints, checkpoints, and communication procedures; but we leave the details to the third party.
在这个语法示例中，必须定义一个新列或者定义一个表级约束。
In this syntax example, you must either define a new column or define a new table-level constraint.
如果您使用like语句创建cgtt表(像普通表一样创建CGTT)，则该语句会执行成功，但CGTT不会继承原始表的约束。
If you create a CGTT table using the like clause (create CGTT like a regular table), the statement will be successful, but the CGTT will not inherit the constraints of the original table.
如果表的主键或惟一性约束中指定了这个列，那么不允许使用这个子句(SQLSTATE 42831)。
