I guess you have a Conceptual Data Model to represent your ER diagram.
我猜您有一个概念数据模型来表示您的 ER 图。
You first need to generate a Physical Data Model from it, using Tools > Generate Physcical Data Model
, picking the specific DBMS you want to use, Microsoft SQL Server 2008, available for PD 15.0 and up.
您首先需要从中生成物理数据模型,使用Tools > Generate Physcical Data Model
,选择您要使用的特定 DBMS,Microsoft SQL Server 2008,可用于 PD 15.0 及更高版本。
And then generate the script using Generate > Generate Database
as mentionned in the first comment.
然后使用Generate > Generate Database
第一条评论中提到的方法生成脚本。
The need to convert the ER diagram into a Physical DAta Model, is that the ER diagram could use some concepts which need to be resolved before going to SQL; and miss some concept specific to the databaase implementation (like performance indexes).
将ER图转换为物理数据模型的需要,是ER图可以使用一些概念,在转SQL之前需要解决;并遗漏了一些特定于数据库实现的概念(如性能指标)。
