I'm having an Active Record in my rails application in which each row of the table MyTable contains:

1. stringArr --> an array of string
2. id

Now I want to query my database to pull all the records in which a particular `queryString` is present in `strinArr` of that record.

I know we can do `MyTable.where(xyz:someXYZ)` to pull all the records with `xyz` value as `someXYZ`?

But how can I do this query?
