如何在Sequelize模型中定义MySQL生成的存储字段

如何在Sequelize模型中定义MySQL生成的存储字段,mysql,sequelize.js,Mysql,Sequelize.js,如果有一个MySQL字段,如 `my_timestamp` datetime GENERATED ALWAYS AS (if((isnull(`another_timestamp_field`) or (`another_timestamp_field` < 100) or (`another_timestamp_field` > 2100000000000)),'9999-12-31 00:00:00',from_unixtime((`another_timestamp_field

如果有一个MySQL字段,如

`my_timestamp` datetime GENERATED ALWAYS AS (if((isnull(`another_timestamp_field`) or (`another_timestamp_field` < 100) or (`another_timestamp_field` > 2100000000000)),'9999-12-31 00:00:00',from_unixtime((`another_timestamp_field` / 1000)))) STORED COMMENT 'something something darkside'
`my_timestamp`datetime始终作为((isnull(`other_timestamp_field`)或(`other_timestamp_field`<100)或(`other_timestamp_field`>210000000000)),'9999-12-31 00:00:00,'unixtime(`other_timestamp_field`/1000))存储注释'something something something something darkside'
如何在Sequelize模型定义中执行类似操作
