使用&Quot；Limit&Quot；和&Quot；Include&Quot；选项时，序列化中出现未知列&Quot；错误(&QOOT；INCLUDE&QUOT；OPTIONS)

我有一个相对复杂的序列化查询，结果是"ERROR：ER_BAD_FIELD_ERROR：UNKNOWN COLUMN‘EventImage.EventId’in‘WHERE子句’"。我可以清楚地看到生成的SQL中的问题，但是我不知道如何解决它。

错误是准确的，因为子查询中生成的WHERE子句引用了子查询中未包括的列。据我所知，Sequelize生成子查询是作为实现行限制的一种方式。

我使用的是Sequelize@2.0.0-dev11、MySQL 5.5.35-0ubuntu0.13.10.2和Node v0.10.21。

以下是基本代码：

var orm = require('../model');
var i = orm.Image;

i.findAll({
    where: where,
    offset: offset,
    limit: rows,
    order: orderby,
    include: [{
        model: orm.User,
        as: 'User'
    },
    {
        model: orm.Event,
        as: 'Events'
    },
    {
        model: orm.Comment,
        as: 'Comments'
    },
    {
        model: orm.Favorite,
        as: 'Favorites'
    }
    ]
})

WHERE="‘Image’.‘Category’=‘Gallery’and‘EventImage’.‘eventID’中 (1，2)"
偏移=0
行=12
orderby="Image.createdAt 说明"

使用以下选项初始化Sequelize：

下划线：false，
FreezeTableName：true，
paranoid：true，
syncOnAssociation：true，
字符集：‘utf8’，
排序： ‘utf8_General_ci’，
时间戳：true

以下是生成的SQL：

解决方案

我不确定是否还需要它，但对于那些正在受苦的人，请尝试添加 subQuery: false到查询。Source.

如果不起作用，请尝试将separate: true添加到子查询中。Source.
