如果您想在相同的文件夹中使用资产负债表和损益表的账户信息，需要在拖入的列数据中正确定义期间。
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。
In our example, the XQuery expression that we pass to XMLEXISTS() is a simple XPath expression where $t is the XML column data: $t/marketinfo/sales/customer/address[zip = "79081"].
在我们的示例中。传递给XMLEXISTS()的XQuery表达式是一个简单的XPath 表达式，其中的 $t 是XML列data：$t/marketinfo/sales/customer/address[zip = "79081"]。
In cases where the platform allows altering the column data type, the list of data types available is pre-filled with the valid compatible data types for that platform, making the type selection easy.
在平台允许更改列数据类型的情况下，可用的数据类型预先填写有该平台的有效兼容数据类型，使类型选择更为容易。
If the column type and the data content are compatible, the data type is successfully altered.
