grails - 如何将列表作为参数添加到grails中的sqlQuery？

Question

我正在编写一个查询并想设置一个字符串列表的参数。

我的查询是

def strQuery = """SELECT * from user u where u.status in (?)"""

def session = sessionFactory.getCurrentSession()

def resultList = session.createSQLQuery(strQuery)
        .setParameter(0, UserStatus.List)
        .list();

在哪里

public enum UserStatus {
    ACTIVE("Active"),
    ARCHIVE("Archived"),

    public static final List<UserStatus> List = [ACTIVE,ARCHIVED]

}

但我遇到了一个异常(exception)

ERROR org.hibernate.util.JDBCExceptionReporter  - ERROR: operator does not exist: character varying = bytea
  Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts.

要绑定(bind)列表，您必须使用 setParameterList带命名参数。
setParameter仅适用于单个值。

def strQuery = """SELECT * from user u where u.status in (:statusList)"""

def session = sessionFactory.getCurrentSession()

def resultList = session.createSQLQuery(strQuery)
    .setParameterList('statusList', UserStatus.List)
    .list();
