Question

我需要一些帮助，以便我可以在grails条件查询中转换我的sql：

String query = """select * from personal_detail as pd
      where pd.id in (
      select u.personal_detail_id from user u where u.id in
      (
        SELECT ur.user_id FROM user_role ur where ur.role_id = '${role.id}'
     )
      and u.enabled = true and u.is_deleted = false
     )
      and
     pd.status = true 
    """

编辑：我被困在内在的选择上，即

SELECT ur.user_id FROM user_role ur where ur.role_id = '${role.id}'

对于内部选择我试过这个：

def results = UserRole.createCriteria().list {
        createAlias('user','user')
            eq('role', role)
            eq('user.enabled',true)
            eq('user.isDeleted',false)

    }

这会产生异常

 Unknown column 'user1_.enabled' in 'where clause'. Stacktrace follows:
Message: Unknown column 'user1_.enabled' in 'where clause'
Line | Method

如果没有看到您的对象模型，很难肯定地说，但您可能正在寻找类似的东西......

def results = UserRole.withCriteria {
    eq 'role', role
    user {
        eq 'enabled', true
        eq 'isDeleted', false
    }
}

我希望有所帮助。
