java - jdbc4.MySQL语法错误异常: error in your SQL syntax; check the manual MySQL server version for the right syntax to use near ') )' at line 1

Question

我在尝试使用 crudRepository 获取数据时遇到问题。 我正在使用 native 查询从数据库中获取记录数，但出现以下错误。

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')  )' at line 1
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) ~[na:1.8.0_171]
at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) ~[na:1.8.0_171]

我在存储库中的查询是:

@Query(value = "select count(1) from user_records upr  where RECORD_ID in  ( SELECT record_id FROM region_record_relation where region_id in :regionIds) ", nativeQuery = true)
public int findAllRecordsforRegionIds(@Param("regionIds") List<Long> regionIds);

我不知道如何解决这个问题。我正在使用 Mysql 数据库。

show-sql 设置已打开。但我得到的是:

Answer 1

@Query(value = "select count(1) from user_records upr  where RECORD_ID in  ( SELECT record_id FROM region_record_relation where region_id in :regionIds) 

应该是

@Query(value = "select count(1) from user_records upr  where RECORD_ID in  ( SELECT record_id FROM region_record_relation where region_id in (:regionIds))) 

有更好的方法可以更有效地编写它。但这应该可以解决错误。
