通过具体实例，阐述了可变栏目报表在应用程序中实现时程序设计的一般方法。
You could do so in the same template, but I choose to create a second template and send the column variable to find the name of the column, as in Listing 6.
您可以在相同的模板上执行这个操作，但是我选择创建另一个模板，然后传递这个列变量来查找列名，如 清单 6 所示。
DB2 passes the same column by default for the variable in case an explicit PASSING clause is not used.
如果没有使用显式的passing子句，默认情况下DB 2将传递相同列给一个变量。
It is common to define an EJB component to correspond to a row in a database, where each persisted variable in the EJB component corresponds to a field (column) in the row.
通常是定义一个对应于数据库中一行的EJB组件，其中EJ b组件中的每个持久性变量对应于行中的一个字段(列)。
Updating XML on the fly means that XML is modified in memory while it is retrieved from an XML variable or column.
动态更新XML意味着当从一个XML变量或列中获得XML时，在内存中修改它。
To use each variable, you simply use the column number as the index of the single value you want.
要使用每个变量，您只需将列号用作您所需值的索引即可。
Note that the row and column order is the same as the element order in each set, and the index variable names are consistent between lines 12, 13, and 14.
注意行和列的次序与元素在每个集合中的顺序是相同的，索引变量名在第12、13和14行是一致的。
NEW_VALUE variable, which can be defined on any column, holds the new value for that column at any given point.
可在任何列上进行定义new _ VALUE变量，该变量在任何给定点保存该列的新列。
If the latter is true, then the indicator variable for that column is set to -5 which will set the column to the default value for that column.
如果是后一种情况，那么该列的指示符变量被设置为- 5，这将把该列的值设置为默认值。
If the former is true, then the indicator variable for that column is set to -1 which results in the column being updated with the null value.
如果是前一种情况，那么该列的指示符变量被设置为- 1，这导致该列被更新为空值。
If the old and new values are the same, then the indicator variable remains as -7 and the column is ignored.
如果新旧值相同，那么指示符变量仍然是- 7，该列被忽略。
Column new_value and old_value variable values can be displayed as part of TTITLE and btitle text, respectively.
new_value和old _ value变量值列可分别作为TTITLE和btitle文本的一部分加以显示。
The var attribute defines an iteration variable used in outputting the column content.
var属性定义一个迭代变量，以便在输出列内容时使用。
When the visualization is calculated, this variable is replaced with all the child tags of the column so that they appear in the correct positions in the page.
当visualization得到核算时，该变量会由列的所有子标签替换，这样它们就会出现在页面中合适的位置中。
Always match the DB2 column data type to the application variable data type, or the JDBC set method.
始终匹配DB 2列数据类型与应用程序变量数据类型或JDBCset方法。
For example even though at design time a variable of data type double can be mapped to a table column of type XML, the run time consequences are unpredictable and hence resulting in errors.
例如，虽然在运行时可以将double类型的变量映射到xml类型的表列，但是这可能导致不可预测的运行时结果，并因此而产生错误。
The propertyTemplate variable is used to locate the property template within the iterative template (for example, to position the Output Text tag inside the Column tag).
propertyTemplate变量用于定位iterative模板中的属性模板（例如，定位Column标签中的OutputText 标签）。
The indicator variable for the column is set to zero for each value that is different.
对于每个不同的值，该列的指示符变量被设置为0。
If XMLQUERY is used within a SELECT statement, the PASSING clause can refer to either a table column or a stored procedure variable.
如果在select语句中使用XMLQUERY，那么passing子句可以引用表列或者存储过程变量。
The variable name is in the column header, in bold type, and matches the name in the Message section.
变量名称位于列标题中，以粗体显示，并匹配Message部分中的名称。
Now a column name is used as the variable name in the Xquery used in these functions.
现在，将一个列名称用作这些函数的Xquery中的一个变量名。
Note that a special annotation is generated for every variable name that is different from its respective mapping column name. The annotation will be of the form.
注意，对于变量名与其所映射的列的名称不相同的每个变量，会生成一个专门的标注。
Prior to the DB2 for I 6.1 release, SQL Update and Insert statements could use an indicator variable with a value of -1 to set a null capable column to the null value.
在DB 2fori 6.1发布之前，SQLUpdate和insert语句能够使用一个值为- 1的指示符变量，将支持空值的列设置为空值。
The only thing worth nothing is that when you declare a new variable (or column) you will need to specify the Type for the variable.
唯一不值得的事情是，当您声明一个新的变量(或者列)时，需要为变量指定Type。
In the following example, variable adrs is either an XML column or a variable of type XML.
在下面的示例中，变量adrs是一个xml列或xml类型的变量。
Some other mappers force you to specify a column six times: in the schema, the getter, the setter, the model's instance variable, the "from" mapping, and the "to" mapping.
其他一些映射器要求指定一个列六次：在模式、getter、setter、模型的实例变量、“from”映射和 “to” 映射中。
In the solidDB example in the right column of Table 3, the status of the INSERT statement is checked using the SQLSUCCESS variable.
在表3右侧列的solidDB示例中，使用SQLSUCCESS变量检查INSERT语句的状态。
The variable association dialog is launched by clicking the value column of the condition row, and selecting Use a variable to return the value in the drop-down box.
通过单击条件行的value列，并在下拉框中选择useavariabletoreturnthe value，可以打开变量关联对话框。
Now you know that the current element being processed is a new column, so you can set the $current_column variable to the number of the column. In this case, columns represent fields
这样，您就知道当前所处理的元素是新列，因而可将 $current_column变量设置为列编号。
Finally, the last step to creating our model is to choose the dependent variable (the column we are looking to predict).
创建模型的最后一个步骤是选择因变量(即我们想要预测的列)。
