如何通过Rails 5迁移在MySQL中添加JSON列 [英] How to add a JSON column in MySQL with Rails 5 Migration

问题描述

我正在尝试通过运行以下命令在MySQL数据库中添加json列:

I'm trying to add a json column in MySQL db by running:

class AddStatisticsToPlayerStatistic < ActiveRecord::Migration[5.0]
    def change
       add_column :player_statistics, :statistics, :json
    end
end

但是当我尝试运行rake db:migrate时出现此错误

But I'm getting this error when I try to run rake db:migrate

Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'json' at line 1: ALTER TABLE `player_statistics` ADD `statistics` json

有人知道如何在MySQL Ver 14.14 Distrib 5.5.53中添加JSON列.正确吗?
