POSTGRES check if a provided value is present in the column of type array

问题

I am trying to check whether a value if present in the column, which is of type array(column_name text[]). As a server i am using hapi and trying to check the same from hapi through query.

Query which i have written is(query is not working):

where: { column_name: { $in: { provided_value} }}

The column contains the values as:

{1234, 3456}

The values are of type text.

Can someone please help me to identify the issue.

Thanks in advance.

回答1:

Sequelize does not support this use of ANY, they seem to only support its use like IN. Instead, you should try the contains operator (@>):

import {Op} from "sequelize";

MyModel.findAll({
  where: {
    column_name: {
      [Op.contains]: [provided_value]
    }
  }
});

This will generate something like

SELECT * FROM "MyModel" WHERE column_name @> '{"provided_value"}';
