When Recieving Key-Value pair, Where the Value is Array. Use IN Instead of =

Feature Request: It would be nice if this same query could be mapped to either = or IN depending on the type of input (array vs string/number)

SELECT * FROM users WHERE ?;

const userIds = [1, 2, 3, 4]; // or const userIds = 1; 
const users = (await con.query(sql, [{userId: userIds}]))[0]

This currently maps to the following string

SELECT * FROM users WHERE `userId` = 1, 2, 3, 4;

Which works fine for the single value example. But it would be nice if the value was an array it could map to:

 SELECT * FROM users WHERE `userId` in (1, 2, 3, 4);

This seems like it wouldn’t be too hard, but I am unaware of any security vulnerabilities such a change could make.

I just want to cut down on the amount of functions I need to have to call specific tables.

For the first query I could obviously call it with a different key and it would still work such as

const emails = "[e-mail]";
const users = (await con.query(sql, [{email: emails}]))[0]

But to my knowledge you cannot currently dynamically change the search param when using IN.

In case anyone finds this and wants the issue in the correct repo: https://github.com/mysqljs/sqlstring/issues/66

You can use in with single values. Need to have one query for = and one for in; just have one with in and it will work for both use cases.
