使用Sequelize时，如何写按位（或）操作？

Question

续集/Postgres

**列 reasoncodes 包含像这样的字符串值。

0,0,0,1,0,0,0,0,0,0,0,0,0**

我们的想法是获取这个值并替换它，使其变成位然后将其与前端传递的值字符串进行比较 (0001000000000)

这适用于 Postgres。

select * from schema.table
where cast(cast(replace(reasoncodes, ',', '') as bit(13)) & cast('0001000000000' as bit(13)) as integer) > 0
and  table.id = 1885

如何将这个where子句转换成Sequelize语法是个问题

Answer 1

您需要使用'Sequelize.literal'，例如：

TableName.findAll({
 where: {
   [Op.and]: [
       Sequelize.literal('cast(cast(replace(reasoncodes, ',', '') as bit(13)) & cast('0001000000000' as bit(13)) as integer) > 0')
   ]
 }
})
