结果两列变量发现的两对典型相关系数都达到显著水平，高职业压力将导致更高的职业倦怠水平，高社会支持水平降低倦怠水平。
Results The two canonical correlation index were significant by two variable lists. The occupational burnout would be greater with the rise of their professional stress.
可以通过访问内部的AppConfig：State数据或作为散列变量值返回给您的散列引用来实现这一步，但我们建议您不要这样做。
You can do it by accessing internal AppConfig: : State data or the hash reference returned to you as the value of the hash variable, but it is not recommended that you do so.
然后，我为所有列创建一个变量。
在标签中定义的列标题变量，是在下一个步骤中被定义的。
The column heading variables, defined in the tag, are defined in the next step.
还可以将变量类型改为与它所映射的列的数据类型不同的类型(见图17)。
Optionally you can also change the variable type name to be different than its mapping columns data type (See Figure 17).
不但可以将它用于表中的列，还可以用于参数和声明的变量。
You can use it not only for columns in a table, but also for parameters and as declared variables.
因此，流开发人员不应该使用变量引用表达式映射到名称列可能为 NULL 的路由决策。
Therefore flow developers should not use routing decisions in which variable reference expressions map onto name columns whose values may be NULL.
为了在报表中正确地显示，这些新的列标题要求设置某些显示变量。
These new column headers require certain render variables to be set in order to be displayed correctly in the report.
一个变量是一个明明的数据列。
该表中与规则变量对应的列，或者来自规则输出定义的物理列，具有与元数据中相应列相同的数据类型。
Columns in this table that correspond to rule variables, or physical columns from the output definition of the rule, have the same data type as the corresponding columns in the data source.
然后表达式中对变量的引用可以静态绑定到本地堆栈框架或一列全局变量的特定槽上。
References to variables within an expression can then be statically bound to a particular slot in either the local stack frame or the list of global variables.
还可以将变量类型改为与其映射的列数据的类型不相同的类型。
Optionally you can also change the variable type name to be different than its mapping columns data type.
第一步是向变量声明部分中添加必需的散列。
The first step is to add the required hash to the variable declaration section.
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)。
Finally, the last step to creating our model is to choose the dependent variable (the column we are looking to predict).
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。
DB2 passes the same column by default for the variable in case an explicit PASSING clause is not used.
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。
NEW_VALUE variable, which can be defined on any column, holds the new value for that column at any given point.
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。
Updating XML on the fly means that XML is modified in memory while it is retrieved from an XML variable or column.
例如，不会在第一次使用时缺省创建变量和散列密钥。
For example, variables and hash keys won't be created on their first use by default.
让我们来研究三类主要的绑定变量：标量、数组和散列。
Let's look at the three main types of tied variables: scalars, arrays, and hashes.
要使用每个变量，您只需将列号用作您所需值的索引即可。
To use each variable, you simply use the column number as the index of the single value you want.
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 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 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.
如果新旧值相同，那么指示符变量仍然是- 7，该列被忽略。
If the old and new values are the same, then the indicator variable remains as -7 and the column is ignored.
将应用程序变量与所产生的结构数据集中的列绑定。
Bind application variables to columns found in any result data set (s) produced.
Expressions窗口在将各列中显示数据，这和变量窗口一样。
Expressions view now displays data in columns just like the variable view.
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。
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.
这不是一个完美的测试 —如果这个变量包含一列用逗号分隔的组“fred,ginger”，则它将匹配 tracexsl:trace 的值 "red" 。
This isn't a perfect test -- if the variable contains the comma-separated list of groups "fred,ginger", it will match a tracexsl:trace value of "red".
修改appconfig散列和数组变量。
