why does spring throw me an exception about bad sql code?

问题

以下是您提供的代码的翻译部分:

@Repository
public interface TeamRepository extends JpaRepository<TeamDAO, String> {

	boolean existsByName(String name);
	
	Optional<TeamDAO> findByName(String name);
	
	@Query("select t.projects from TeamDAO t where t.name = :name")
	Page<ProjectDAO> getProjectsByName(@Param("name") String name, Pageable page);
	
	default TeamDAO getTeam(String name) {
		return findByName(name).orElseThrow(() -> new NotFound404Exception(notFound(TEAM, name)));
	}
	
	default TeamDAO getDependency(String name) {
		return findByName(name).orElseThrow(() -> new FailedDependency424Exception(failedDependency(TEAM, name)));
	}
	
	default void existsDependency(String name) {
		if (!existsByName(name))
			throw new FailedDependency424Exception(failedDependency(TEAM, name));
	}
}

使用@Query注解的部分引发异常:

java.sql.SQLSyntaxErrorException: 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 ') as col_0_0_ from teams teamdao0_ cross join projects_teams projects1_, project' at line 1

英文:

Im working in an app that has a spring boot server. the thing is that i have a query, not auto generated one, that throws me a bad sql exception and i cant seem to find out why.
Also im using MySQL as a database
this is my repository code :

@Repository
public interface TeamRepository extends JpaRepository&lt;TeamDAO, String&gt; {

	boolean existsByName(String name);
	
	Optional&lt;TeamDAO&gt; findByName(String name);
	
	@Query(&quot;select t.projects from TeamDAO t where t.name = :name&quot;)
	Page&lt;ProjectDAO&gt; getProjectsByName(@Param(&quot;name&quot;) String name, Pageable page);
	
	default TeamDAO getTeam(String name) {
		return findByName(name).orElseThrow(() -&gt; new NotFound404Exception(notFound(TEAM, name)));
	}
	
	default TeamDAO getDependency(String name) {
		return findByName(name).orElseThrow(() -&gt; new FailedDependency424Exception(failedDependency(TEAM, name)));
	}
	
	default void existsDependency(String name) {
		if(!existsByName(name))
			throw  new FailedDependency424Exception(failedDependency(TEAM, name));
	}
}

The one with the @Query annotation throws me:

java.sql.SQLSyntaxErrorException: 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 &#39;) as col_0_0_ from teams teamdao0_ cross join projects_teams projects1_, project&#39; at line 1

Can anyone tell me what im doing wrong? I've tried reworking the code but it seems to me it just doesnt

logs as requested (i think its this)

Hibernate: select projectdao2_.id as id1_2_, projectdao2_.created_by as created_2_2_, projectdao2_.created_date as created_3_2_, projectdao2_.description as descript4_2_, projectdao2_.features as features5_2_, projectdao2_.last_modified as last_mod6_2_, projectdao2_.last_modified_by as last_mod7_2_, projectdao2_.name as name8_2_, projectdao2_.os as os9_2_ from teams teamdao0_ inner join projects_teams projects1_ on teamdao0_.id=projects1_.teams_id inner join projects projectdao2_ on projects1_.projects_id=projectdao2_.id where teamdao0_.name=? order by teamdao0_.name asc limit ?
Hibernate: select count(.) as col_0_0_ from teams teamdao0_ cross join projects_teams projects1_, projects projectdao2_ where teamdao0_.id=projects1_.teams_id and projects1_.projects_id=projectdao2_.id and teamdao0_.name=?

EDIT: I can tell is something to do with the pageable object. I mean its when there are more objects that what can fit in a page. I had pages of ten by default, and there are 12 objects, didnt work, when they fit in a single page (here i increased page size to 15) it works.

EDIT: Project and Team classes

public class ProjectDAO extends BaseEntity implements DAO {
	
	private static final long serialVersionUID = -2990447415589237412L;
	
	@Column(unique = true, updatable = false)
	private String name;
	
	@Column(length = 1024)
	private String description;
	
	private String features, os;
	
	@LastModifiedDate
	private long lastModified;

	@CreatedDate
	private long createdDate;
	
	@CreatedBy
	private String createdBy;
	
	@LastModifiedBy
	private String lastModifiedBy;
	
	@ToString.Exclude
	@EqualsAndHashCode.Exclude
	@ManyToMany(cascade = { CascadeType.PERSIST , CascadeType.MERGE, CascadeType.REFRESH })
	private Set&lt;TeamDAO&gt; teams;

	@ToString.Exclude
	@EqualsAndHashCode.Exclude
	@ManyToMany(cascade = { CascadeType.PERSIST , CascadeType.MERGE, CascadeType.REFRESH })
	private Set&lt;ClientDAO&gt; clients;

	private String leader;
	
	@LastModifiedDate
	private long lastModified;

	@CreatedDate
	private long createdDate;
	
	@CreatedBy
	private String createdBy;
	
	@LastModifiedBy
	private String lastModifiedBy;

	@ToString.Exclude
	@EqualsAndHashCode.Exclude
	@OneToMany(mappedBy = &quot;team&quot;, cascade = { CascadeType.PERSIST , CascadeType.MERGE, CascadeType.REFRESH })

似乎 Hibernate 在生成用于计算结果页数的计数语句时出现了问题,可能是因为在你的多对多关系中缺乏显式联合表的定义。无论如何,你可以尝试为查询显式定义一个计数语句,就像这样:

@Query(value = "select t.projects from TeamDAO t where t.name = :name", countQuery = "select count(p) from TeamDAO t inner join t.projects as p where t.name = :name")
Page<ProjectDAO> getProjectsByName(@Param("name") String name, Pageable page);
英文:

Seems like hibernate is having problems generating the count statement for calculating the amount of pages of the results, might be due to the lack of an explicit definition of a joint table for your many to many relationship, in any case you can try explicitly defining a count statement for your query like this

@Query(value = &quot;select t.projects from TeamDAO t where t.name = :name&quot;, countQuery = &quot;select count(p) from TeamDAO t inner join t.projects as p where t.name = :name&quot;, )
Page&lt;ProjectDAO&gt; getProjectsByName(@Param(&quot;name&quot;) String name, Pageable page);
