Question

This is the mysql code written for ruby on rails application

Model.find_by_sql(["SELECT * FROM domainurls WHERE domaindetail_id = ?",@id ,"and count IN (SELECT Max( count ) FROM domainurls WHERE domaindetail_id =?",@id,")"])

It gives me error

"error is: wrong number of arguments (0 for 1)"

Can anybody have idea what’s wrong in the code?

Answer 1

Here you require data in two query because of IN can search data within an array.
Either your query

(SELECT Max( count ) FROM domainurls WHERE domaindetail_id =?",@id,")

will return many column.

So first execute this query and take counts in a array and after that execute second query.

I think you have understood.
