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。

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。
