Working with = ANY ($1) with array binding fails in Redshift

Here is my test. Apologies, I don’t have a Redshift database available that you can use to test. You’ll need a Redshift database with table “table_with_ids” with column “my_id” and 2 rows:

my_id

1 2

Here is my code:

const pg = require('pg');

const query = `
   SELECT count(1) 
     FROM table_with_ids
    WHERE my_id = ANY ($1)`;

const config = {
    // need connection to Redshift database...
};

// instantiate a new client with config
const client = new pg.Client(config);

const bindVars = [[1,2]];

// connect to our database
client.connect((err) => {
    if (err) throw err;

    // execute a query on our database
    client.query(query, bindVars, (err2, result) => {
        if (err2) {
            console.log(err2.detail); // shows odd error
            throw err2;
        }

        // just print the result to the console
        console.log(result.rows[0]); // should output: { count: 2 }

        // disconnect the client
        client.end((err3) => {
            if (err3) throw err3;
        });
    });
});

Here is the text returned from the “console.log(err2.detail)” statement:

  -----------------------------------------------

I faced the same issues and managed to get it working with the below code using https://github.com/lib/pq

v, _ := pq.Array([]int{1,2,3}).Value()
query := fmt.Sprintf(`select * from table where colID = any('%v'::integer[]);`, v)
rows, err := db.Query(query)

Hope it helps someone in the future!
