目标表受保护,源表不受保护。
The target table is protected, and the source table is unprotected.
源表受保护,目标表不受保护。
The source table is protected, and the target table is unprotected.
在这个示例中,源表的定义如下。
步骤3:将源表添加到数据流。
可在源表及目标表上定义多个触发器。
Multiple triggers can be defined on source and target tables.
源表和目标表定义必须匹配。
当然,昵称又引用源表。
Of course, the nicknames in turn refer to the source tables.
编辑DB 2源表阶段。
有时候,源表中的一行不具有有效的坐标值。
Sometimes, a row in the source table does not have valid coordinate values.
接下来我们看看ccd表与源表有什么不同。
So now let's look at how CCD tables are different from the source tables.
merge语句遵循目标表或源表上的约束。
Merge statements follow the constraints on target or source tables.
更改是通过在源表中创建的触发器完成跟踪的。
Changes are tracked through triggers that are created on the source table.
对于源表及目标表采用相同的安全策略进行保护。
Both source and target tables are protected by the same security policy.
如果源表很大,那么这可能导致逻辑日志的溢出。
If the source table is large, this may cause an overflow of the logical log.
图1展示了一个例子,其中源表与目标表合并了。
Figure 1 shows an example where the source and target table rows are merged.
而且,嵌套循环联接方法用于联接源表与目标表。
Also, the nested loop join method is used to join the source and target tables.
源表必须可删除。
正如上面提到的,必须假设源表包含纬度和经度值。
As mentioned above, you must assume that the source table contains latitude and longitude values.
源表和目标表使用的XML数据格式必须相同。
XML data formats used by the source and target tables must be the same.
检查错误表就能够方便地查明源表行以及出问题的坐标。
Inspection of the error table conveniently reveals the source row as well as the problematic coordinate.
昵称是在联邦数据库内创建的,用于标识数据源表和视图。
Nicknames are created in the federated database to identify data source tables and views.
源表的变更将以xml格式或是其它数据格式发布到消息队列。
Changes from source tables are published in XML format or other data formats to a message queue.

对源表的更改或事件从日志中进行捕获,并转换为xml格式的消息。
Changes to source tables, or events, are captured from the log and converted to messages in an XML format.
图2总结了本文中代码示例所使用的表结构,假设源表代表水井的位置。
Figure 2 summarizes this for the example I use for the code samples throughout this article, assuming a source table that represents well locations.
在SourceTables页面上,选择需要进行复制的源表。
On the Source Tables page, select the source table that you want to replicate from.
