@Query（Spring data / JPA），其中boolean在where条件中

Posted 2021-04-13

SampleRepository.java类有如下查询：

@Query("select eq from EmailQueue eq where eq.inquiry in (select issue.id from Inquiry issue  where issue.id = eq.inquiry and systimestamp   >= eq.sendDate + (1/24) * ?3  ) and "
            + " systimestamp   >= eq.sendDate + (1/24) * ?2 and eq.sent = True and "            
            + " eq.emailType.id = ?1  "
            + "  order by eq.sendDate asc")

我得到的错误是：

Caused by: java.sql.SQLSyntaxErrorException: ORA-00904: "TRUE": invalid identifier

你能告诉我如何在@query中指定eq.sent = True吗？我也尝试了eq.sent = 1，它不能正常工作。

答案

您可以使用is而不是=：

@Query("select eq from EmailQueue eq where eq.inquiry in (select issue.id from Inquiry issue  where issue.id = eq.inquiry and systimestamp   >= eq.sendDate + (1/24) * ?3  ) and "
            + " systimestamp   >= eq.sendDate + (1/24) * ?2 and eq.sent is True and "            
            + " eq.emailType.id = ?1  "
            + "  order by eq.sendDate asc")

另一答案

通过以下解决方法解决：

 @Query("select eq from EmailQueue eq where eq.inquiry in (select issue.id from Inquiry issue  where issue.id = eq.inquiry and systimestamp   >= eq.sendDate + (1/24) * ?3  ) and "
                + " systimestamp   >= eq.sendDate + (1/24) * ?2 and eq.sent = ?4 and "          
                + " eq.emailType.id = ?1  "
                + "  order by eq.sendDate asc")
List<EQueue> findEmailSentDetails(long type, int days1, int days2,boolean emailSent);

而不是使用“eq.sent = true”传递true作为参数，如eq.sent =？4
