GORM选择加入

Question

我在Grails中遇到GORM问题。我有两种关系，看起来像这样：

Company

static hasMany = [
            users:User,
]
---------
User
// no mention about entity Company

我需要获得与某个用户相关的所有公司。

    User user =  springSecurityService.currentUser

def results = Company.executeQuery("select c from Company c join User u where u.id = ${user.id}") 

我需要的SQL语法如下所示：Select * from Company C join User u on u.company_id=c.id where u.id=user.id.

我的错误是：Path expected for join!

在数据库中创建了一个新的连接表，它的名称为company_user。知道怎么写这个简单的选择吗？

Answer 1

这应该有效

User user = springSecurityService.currentUser
def results = Company.executeQuery(
        "from Company c join c.users u where u.id = ?", [user.id])
