Arrays SequelizeDatabaseError:运算符不存在：字符变化[]@>；字符变化

当我试图在数组数组中搜索一个数组值时，出现上述错误。我的代码：

    sequelize.define('room', {
    'id' : {'type' : DataTypes.INTEGER, 'primaryKey' : true, 'autoIncrement' : true},
    'tutor' : {'type' : DataTypes.INTEGER, 'allowNull' : false},
    'students' : {'type' : DataTypes.ARRAY(DataTypes.STRING), 'allowNull' : false},
    'subject' : DataTypes.STRING,
    'date_time' : DataTypes.DATE,
    'status' : {'type' : DataTypes.STRING , 'defaultValue' : "active"},
  }
)

var queryString = "Select * from rooms where status = :statusVar and students @> ANY(:stuArray::character varying[]) ORDER BY CASE when :orderingVar = 'date_time DESC' then date_time end DESC, case when :orderingVar = 'date_time' THEN date_time end ASC OFFSET :offsetNumber LIMIT :limitNumber;"

    return sequelize.query(queryString,{ 
                      replacements:{ 
                        statusVar: status,
                        orderingVar: orderVar, 
                        limitNumber: itemPerPage, 
                        offsetNumber: ((pageNumber-1)*itemPerPage),
                        tutArray: '{' + tutorUserId.toString() +'}',
                        stuArray: ['{' + studName.toString() + '}']
                      }, 
                        type: sequelize.QueryTypes.SELECT})

其中studName=[Emily，John，Dexter]

我想找到“学生”列中包含任何学生姓名的所有记录，即Emily、John或Dexter，我最后做了以下工作，结果成功了

var queryString = "Select * from rooms where students && :stuArray::varchar[] and status = :statusVar ORDER BY CASE when :orderingVar = 'date_time DESC' then date_time end DESC, case when :orderingVar = 'date_time' THEN date_time end ASC OFFSET :offsetNumber LIMIT :limitNumber;"

“&&”是重叠（有公共元素）运算符Ex:ARRAY[1,4,3]&&ARRAY[2,1]返回true。请注意，运算符的右侧也应该是以下格式的数组

stuArray:['{'+studName.toString（）+'}]

，即

['{Emily，John，Dexter}']
