Oracle 中的 DEFAULTS 关键字

顾名思义，在创建表、要素类、栅格数据集以及索引时，默认情况下使用 DEFAULTS 配置关键字下的设置。如果在地理数据库中创建数据时未指定其他关键字，或者指定的关键字缺少某些必要参数，则将使用 DEFAULTS 关键字中的值。

您需要提供在方括号 (<>) 中显示的信息，并移除 # 符号取消关联 TABLESPACE 行的注释。对于归属于 DEFAULTS 关键字的参数，所设置的参数值应适用于地理数据库中的多数数据。如果不取消 TABLESPACE 行的注释，也不提供相关值，则数据将存储在创建数据用户的默认表空间中。

注：

UNICODE_STRING 参数默认不存在。但是，Oracle 新的 ArcSDE 地理数据库将使用 Unicode 编码。要更改此设置，必须将 UNICODE_STRING 参数添加至 DBTUNE 表并将其设置为 FALSE。
