Enter a value in the CustomerID field.
在CustomerID字段中输入一个值。
Rename attribute4 to customerID and leave string as the type.
将attribute4 重命名为customerID，并保留string 类型。
First select the field element and wire it to the target CustomerID element.
首先，选择field元素，并将其连接到目标CustomerID元素。
Recall that the XML column in the "items" table contains a "CustomerID" element.
还记得吗，“items ”表中的xml列包含一个“CustomerID ”元素。
For example, you want to query the process instance by customerId instead of orderNo.
例如，您想要根据customerid而非orderno查询流程实例。
You need to add a new custom property called “customerId” to support the new query requirement.
您需要添加一个新的名为 “customerId” 的自定义属性来支持新的查询要求。
This means that you have to pass to the query not only the customerid but also the insurance rates.
这意味着，不但要向查询传递customerid，还要传递保险费率。
Click Insert object field and select CustomerID from the list of event fields, as shown in Figure 6.
单击Insertobjectfield并从事件字段列表中选择CustomerID，如图6所示。
The call to the stored procedure takes in two runtime parameters, the customerid and the insurance XML.
对这个存储过程的调用接受两个运行时参数，customerid和保险XML。
Now you can query the to-do task by the the new custom property, customerId, to meet the new requirement.
现在，您可以根据新的自定义属性customerId 来查询待处理任务，从而满足新的需求。
Listing 8 shows how to extract the customerid from the XML and use it to create an update SQL command for the database.
清单8演示如何从XML中提取出customerid并用它创建更新数据库的sql语句。
On the General tab of the Properties pane, add $field[@name='CustomerID'] as a custom XPath expression as shown in Figure 25.
在Properties窗格的General选项卡上，将 $field[@name='CustomerID']作为自定义XPath表达式添加，如图 25 中所示。
Here, XMLExists determines if the "CustomerID" value in one target source is equal to a value derived from another target source.
这里，XMLExists决定在一个目标源中的“CustomerID ”值是否等于来自另一个目标源的值。
Create an inline map between the source CustomerID and the target Field array index 2, using CustomerID for the name attribute and String for the type attribute.
在源customerid和目标Field数组索引2创建内联映射，对name属性使用CustomerID，对type属性使用String。
Using the trigger column "CustomerID," the output will generate a new record containing a single XML document only when the "CustomerID" field is changed to a new value.
通过使用触发器列“CustomerID”，仅当“CustomerID”字段被更改为一个新值时，输出将生成一条包含一个XML文档的新记录。
For example, if you are creating a Customer table and the CustomerID is marked as not null, then when you define the primary key, CustomerID will show as a candidate column.
例如，如果您要创建一个Customer表并且CustomerID 被标记为not null，则当您定义主键时，CustomerID将会显示为备选列。
Update 14 USES the relational column value "CID" in the transform expression to produce a new element "customerid" as the first element under the root element "customerinfo."
更新14在转换表达式中使用关系列“CID”生成新元素“customerid”并让它成为根元素“customerinfo”下的第一个元素。
Since customerid is an attribute in the original customer profile that was sent to the client, there is no need to send an extra parameter for the customer id in the request.
因为customerid是原来发送给客户机的客户个人信息中的一个属性，所以在请求中不需要为客户id发送额外参数。
Notice how the values from the map payload are used to populate the XML elements: some of the naming convention mismatches are resolved here (for example, clientId becomes customerId).
注意mappayload中的值是如何用于组装XML元素的：这里解决了一些不匹配的命名约定（比如将clientId转换为customerId）。
