[我看到放置在Ignite spring数据的@query（org.apache.ignite.springdata.repository.config.Query）中的删除查询无法类似于通过cache＃query（）执行删除查询，而是尝试执行查询重写不能正确获取子查询中的键，从而导致H2引擎因无效的SQL错误而导致失败。下面是一个例子，
Spring Data @Query
@Query("delete from EMPS.EMP WHERE EMPNO = ? AND ENAME = ?")
void deleteEmpByEmpNoAndEName(final Integer empno, final String ename);
失败，出现以下错误
javax.cache.CacheException: Failed to parse query. Syntax error in SQL statement "SELECT ""EMPS"".""EMP""._KEY, ""EMPS"".""EMP""._VAL FROM ""EMPS"".""EMP"" WHERE DELETE FROM[*] EMPS.EMP WHERE EMPNO = ? AND ENAME = ? "; SQL statement:
SELECT "EMPS"."EMP"._KEY, "EMPS"."EMP"._VAL FROM "EMPS"."EMP" WHERE delete from EMPS.EMP WHERE EMPNO = ? AND ENAME = ? [42000-195]

同样通过cache＃query（）
gnition.ignite().cache("EmpCache").query((new SqlFieldsQuery("delete from EMPS.EMP WHERE EMPNO = ? AND ENAME = ?").setArgs(empno, "Neo")));
这将正确执行（我假设在服务器节点上）并删除条目。
两个人的工作方式是否相同？是Ignite spring数据实现中的错误，还是我做错了。。感谢您的反馈。
谢谢
我认为我们在查询中不支持DELETE。
您应使用IgniteRepository.delete(key)。
删除和更新语句应在最新版本中受支持。但是关键字的情况下存在一个已知的错误。您可以尝试将“删除”替换为“删除”，然后再试一次。
