合成标识
适用于 ✅ 开源版 ✅ 专业版 ✅ 企业版
如果数据库报告 jOOQ 的代码生成器将识别标识列。某些数据库不支持“真实的”标识列,但允许模拟它们,例如,通过触发器和序列(例如 12c 之前的 Oracle)。如果某个列是已知的“标识”,但不是正式标识,则用户可以指定正则表达式来匹配所有表和列,这些表和列将被视为正式标识。例如

Gradle(第三方)
<configuration> <generator> <database> <syntheticObjects> <identities> <identity> <!-- Optional regular expression matching all tables that have this identity. --> <tables>SCHEMA\.TABLE</tables> <!-- List all columns that are identities --> <fields>ID</fields> </identity> </identities> </syntheticObjects> </database> </generator> </configuration>

// The jOOQ-codegen-gradle plugin has been introduced in version 3.19. // Please use the official plugin instead of the third party plugin that was recommended before.
一如既往,当使用正则表达式时,它们是具有默认标志的正则表达式。
