使用Oracle Sql Developer生成DDL以包含外键

Question

我尝试了几种使用SQL Developer从Oracle数据库生成DDL的选项，但它们都不符合目的。

快速DDL选项导致无外键约束的DDL。我喜欢的格式

编辑表格导致DDL包括存储和日志，我无法摆脱。

想知道任何人都有更好的方式使用SQL Developer生成DDL吗？

感谢

快速DDL不使用任何类型的偏好，它被我们认为是适当的做了 - 这完全是主观的过程。

但是，如果您转到树中对象的SQL页面，则会根据首选项>数据库>导出中设置的首选项生成DDL。

对于4.2版本，你也可以在工作表中使用DDL命令。您可以使用SET DDL关闭或打开您想要生成的DDL类型。

SET DDL PRETTY ON; 
SET DDL CONSTRAINTS ON; 
SET DDL REF_CONSTRAINTS ON; 
SET DDL PARTITIONING ON; 
SET DDL TABLESPACE OFF; 
SET DDL SEGMENT_ATTRIBUTES OFF; 
SET DDL STORAGE OFF; 

DDL EMPLOYEES
