HQL查询语法

Question

我正在尝试获取具有多个“教育”的员工列表，每个员工都有一个“教育类型”

因此，Employee具有一系列的教育，每种教育都有一个带有名称的类型。

    def unchecked = educationTypes?.unchecked
    String query = "FROM Employee e, IN (e.education)  AS ed WHERE ed.type.name IN (:typeNames)";

    def matches = Employee.executeQuery(query, [typeNames: unchecked]);

上面的查询给我以下内容：

Stacktrace follows:
org.hibernate.hql.ast.QuerySyntaxException: unexpected token: ed near line 1, column 39 [FROM Employee e, IN (e.education)  AS ed WHERE ed.type.name IN (:typeNames)]
    at $Proxy12.createQuery(Unknown Source)

所以我试图弄清楚如何正确地访问它。 非常感谢您的帮助

尝试这样的事情：

Employee.executeQuery("""
    select e from Employee e, Education ed 
    where ed.employee = e and ed.type.name IN (:typeNames)
""", [typeNames: [...]])
