Hibernate-. ast.Query语法异常:意外的AST节点错误?


我的JPQL查询如下-

@Query("SELECT p.packageName FROM Packages p WHERE CASE WHEN :packageId IS NULL THEN TRUE WHEN p.packageId.packageId=:packageId THEN TRUE ELSE FALSE END")
List<String> getPackageByAccountIdAndPackageId(Long packageId);

我在编译上述代码时遇到以下错误-

Caused by: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected AST node: CASE near line 1, column 80 [SELECT p.packageName FROM com.entities.Packages p WHERE CASE WHEN p.packageId.packageId IS NULL THEN TRUE WHEN p.packageId.packageId=:packageId THEN TRUE ELSE FALSE END]

关于如何解决这一问题的任何指导/帮助将不胜感激。

我正在使用spring-data-jpa-2.1.7。释放和Hibernate核心-5.3.10.FINAL

就像我已经在话语上回答的那样,你必须使用这样的查询:

SELECT p.packageName 
FROM Packages p 
WHERE p.packageId.packageId IS NULL 
OR p.packageId.packageId=:packageId
