当您想要在滚动或查看其他列数据时冻结一个或一组列时将会很有用。
Column locking is useful for when you want to freeze a column or collection of columns while scrolling and reviewing data in the other columns.
num_quantiles数据库配置参数指定应将列数据值分成的组数。
The num_quantiles database configuration parameter specifies the number of sections into which the column data values should be grouped.
例如，您可以将源系统上较小的列数据长度复制为目标系统上较大的数据长度。
For example, you can replicate from small column data lengths at the source to larger data lengths at the target.
若选择一列，Explorer窗口的右侧就会显示数据集内该列数据的信息。
By selecting each column, the right section of the Explorer window will also give you information about the data in that column of your data set.
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。
Always match the DB2 column data type to the application variable data type, or the JDBC set method.
首先，确保已经针对列数据类型使用恰当的setxxx方法将数据绑定到参数标记。
First, ensure the data is bound to parameter markers using the correct setxxx method for the column data-type.
还可以使用AES_ENCRYPT和AES_DECRYPT函数对列数据进行加密和解密。

在这些属性中，rows尤其方便，因为您可以使用它来在整个结果集中进行迭代和根据名字访问列数据。
Of these properties, rows is particularly convenient, because you can use it to iterate through the result set and access the column data by name.
他们采用这种格式，平均减少了20%的存储需求，同时可以达到更好的性能(按需延迟对列数据的解压)。
They have adopted this format and are seeing reduced storage requirements of about 20% on average and they can achieve improved performance by using it (by lazily decompressing columns as needed).
DB 2对其涉及传统关系数据和xml列数据的常用服务进行了扩展，例如优化、索引、并行控制和实用工具。
DB2 extends its common services, such as optimization, indexing, concurrency control, and utilities, across the traditional relational and XML column data.
如果编目中没有列数据值分布信息，DB 2就会假设值是均匀分布的，这可能导致优化器选择非最优的访问路径。
Without column data-value distribution information in the catalog, DB2 will assume an even distribution of values, which may lead the optimizer to a sub-optimal access path.
如果需要在修改列数据类型期间对数据库执行写访问，可以使用下一小节描述的ADMIN_MOVE_TABLE例程。
If you need to have write access to the database available while column data type is changed, you can use of ADMIN_MOVE_TABLE routine described in the next section.
在获取XML数据时，应用程序也获取那个列数据以便识别XML schema，并基于该schema处理XML数据。
When getting XML data, the application also gets the column data for identifying the XML schema, and processes the XML data based on it.
