resultset

Obviously , a stored procedure doesn 't have to return a resultset .

显然，存储过程不一定非要返回结果集。

The appropriate resultset is calculated and then returned .

数据库会计算出适当的结果集然后返回它们。

Use an updatable ResultSet to retrieve and UPDATE one row at a time .

使用可更新的ResultSet一次仅获取和UPDATE一个行。

The key concept is the introduction of a new , special row in the ResultSet , called the insert row .

主要思想是把一个特殊的新行引入到ResultSet中，称为insertrow。

Each value retrieved via the enumerator should correspond with one row of the resultset .

通过枚举器检索的每个值都应与结果集的一行对应。

This is ideal when the entire resultset is not actually required , since it more effectively uses the available memory .

当实际上并不需要整个结果集时，这将是理想的，因为它能够更有效地使用可用内存。

One other important point is that you can continue to work with an updateable ResultSet after inserting new rows .

另一个重要的要点是在插入新行之后可以继续使用可更新的ResultSet。

JDK6.0 also provides updater methods in the ResultSet interface to update SQLXML values .

JDK6.0Beta还在ResultSet接口中提供了一些updater方法来更新SQLXML值。

Move the ResultSet cursor to insert a row .

可以移动ResultSet游标来插入一个行。

Again , this is very similar to a ResultSet .

再一次强调，这和ResultSet十分相似。

Next , you learned how to achieve similar functionality from within a Java program by creating an updateable ResultSet .

接下来，学习了通过创建可更新的ResultSet在Java程序中实现类似的功能。

As you may imagine , a common business need is to modify specific column values as you iterate through the rows in a ResultSet .

正如您想象的那样，常见的业务需求是在循环访问ResultSet中的行时修改特定的列值。

In this example , that 's before the first row , so a call to the next () method retrieves the first row in the ResultSet .

在本例中，那是在第一行之前，因此调用next（）方法将检索到ResultSet中的第一行。

Underneath , you can visualize a JDBC ResultSet object being returned and its contents being passed into a for loop .

在底层，您可以看到返回了JDBCResultSet对象，它的内容被传递进for循环。

The next few sections demonstrate how you can use the JDBC API to selectively update , delete , or insert new data into a ResultSet .

接下来的几个部分将演示如何使用JDBCAPI有选择性地更新、删除数据或把新数据插入ResultSet中。

But what if the languages are stored in a java . io . File ? How about a JDBC ResultSet ?

但是如果语言存储在java.io.File，那该怎么办？

The next step is to create the updateable ResultSet , which is the equivalent of using the GET CURSOR command within the ij tool .

下一步是创建可更新的ResultSet，方法为在ij工具内使用GETCURSOR命令。

Then we can populate the new row using update methods given to us by our parent ( or more appropriately , our grandparent ) ResultSet interface .

然后，我们可以用“父（更确切地说是‘祖父’）ResultSet接口”给予我们的更新方法来填充新行。

When writing Java code to create the updateable ResultSet , the only change you need to make is to pass two parameters into the createStatement () method .

当编写Java代码来创建可更新的ResultSet时，您需要做出的惟一更改是把两个参数传递到createStatement（）方法中。

The ResultSet allows you to iterate over each QuerySolution returned by the query , providing access to each bound variable 's value .

ResultSet支持在查询返回的每个QuerySolution上进行迭代，这提供了对每个绑定变量值的访问。

The SQL Maps framework will create a PreparedStatement instance , set any parameters using the provided parameter object , execute the statement , and build a result object from the ResultSet .

SQLMaps框架将创建一个PreparedStatement实例，使用所提供的参数对象设置所有参数、执行语句以及从ResultSet中构建一个结果对象。

The returned object from a query is an ObjectSet , which is similar to a JDBC ResultSet in that it 's a simple container of objects .

查询返回的对象是一个ObjectSet，它类似于一个JDBCResultSet（一个简单的对象容器）。

This will re-populate the resultset in the DataSet , so the contents of the DataGrid will automatically be updated .

这将重新填充DataSet中的结果集，因此DataGrid的内容将自动更新。

The valid values for these parameters reflect the values supported by the JDBC API ( You can check the supported values by referring to the JDBC ResultSet API page ) .

这些参数的有效值反映JDBCAPI支持的值（可以参考JDBCResultSetAPI页面查看受支持的值）。

In order to access all the information returned by a stored procedure call , developers need to register all the output parameters beforehand and assign the result of the call to a ResultSet object .

为了访问存储过程调用返回的所有信息，开发人员需要预先注册所有的输出参数，并将调用的结果赋给一个ResultSet对象。

The JDBC API includes many methods you can use to move around within a scrollable ResultSet ( to move around in a forward-only ResultSet , you use the next () method ) .

JDBCAPI包括可以用于在可滚动ResultSet内移动的许多方法（要在只能向前移动的ResultSet中移动，可使用next（）方法）。

The difference is that the query language is MDX , not SQL , and the result is a multidimensional CellSet , not a ResultSet consisting of rows and columns .

所不同的是，查询语言是MDX而非SQL，而且结果是个多维的CellSet，而不是由行和列组成的ResultSet。

Alternatively , to update ResultSet from a current row , in a scrollable ResultSet , move to a ResultSet row with an absolute ( int ) or relative ( int ) method .

此外，要在可滚动的ResultSet中从当前行更新ResultSet，需要使用absolute（int）或relative（int）方法移动到ResultSet行。

Results flow from the bottom of the run tree ( leaf nodes ) to the top ( XTree node ) where the result is represented in RSAPI ( Resultset API ) format and can be sent to the report service for rendering .

结果从运行树（叶子节点）流到顶部（XTree节点），其中结果以RSAPI（ResultsetAPI）格式表示，且可被发送到报表服务以供呈现。
