使用gocql在Cassandra查询中的可变参数

Question

I want to make a generic function for performing cassandra queries using the gocql client, something like :

queryExec("INSERT INTO USERS VALUES(?,?,?,?)", userId, emailId, mobileNo, gender)

func queryExec(query string, args ...interface{}) err{
err := session.query(query, args).Exec()
return err

}

but when I pass it multiple argument values, it gives me the following error :

gocql : expected 4 values send got 1

Answer 1

It should be

err := session.query(query, args...).Exec()

Without the ellipsis, query receives a slice containing all the args.
