jOOQ 内置方法生成具有完全限定的“列”名称的不确定查询

【中文标题】jOOQ 内置方法生成具有完全限定的“列”名称的不确定查询

【英文标题】：jOOQ inbuilt method generates uncertain query which has fully qualified "column" name

【问题描述】：

我正在开发 Spring Boot 并连接到 PostgreSQL 并使用 jOOQ。

jOOQ 的 DSLContext 内置“更新”方法生成具有完全限定列名的不确定查询。在 PostgreSQL 上运行时会抛出 BadSqlGrammerException。

使用的内置方法：

dslContext.update(Tables.TEST).set(row(Tables.TEST.COLUMN1, Tables.TEST.COLUMN2),
                row(col1, col2))
                .where(Tables.TEST.COLUMN3.eq(col3))
                .execute();

生成的查询：

update "abc"."test" set "abc"."test"."column1" = ?, "abc"."test"."column2" = ? where "abc"."test"."column3" = ?;

发生异常：

"message": "Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.jdbc.BadSqlGrammarException: jOOQ; bad SQL grammar [update \"abc\".\"test\" set \"abc\".\"test\".\"column1\" = ?, \"abc\".\"test\".\"column2\" = ? where \"abc\".\"test\".\"column3\" = ?]; nested exception is org.postgresql.util.PSQLException: ERROR: column \"abc\" of relation \"test\" does not exist\n Position: 30]",

堆栈跟踪：

org.postgresql.util.PSQLException: ERROR: column \"abc\" of relation \"test\" does not exist
 Position: 30

这种情况只发生过一次，我无法重现此问题

请帮助解决这个问题。

【参考方案1】：

如果发生这种情况，则说明您使用的 SQLDialect 不正确。堆栈跟踪（您省略了）应该表明您的案例中使用了 SQLDialect。

【讨论】：

用 Stack Trace 更新了问题

你的意思是在应用程序属性文件中包含“spring.jooq.sql-dialect = Postgres”并且这个问题不会重复吗？

@BrajeshJha：好吧，看起来堆栈跟踪不是来自 jOOQ 的 DataAccessException 的那个，它包含 SQLDialect。无论如何，您可以轻松检查。只需登录 dslContext.dialect() 即可查看您配置 jOOQ 的方言。我无法告诉您为什么配置错误，可能有多种原因，但这就是这里发生的情况。

Postgres 是配置的方言。我已经在更新方法生成不确定查询的地方准确记录了这一点： logger.info("SQLDialect Used --> ",dslContext.dialect()); "message":"使用的 SQLDialect --> POSTGRES"

@BrajeshJha：但是，也许你没有显示你正在执行的 exact 代码？
