Solution 2

"I need to know which id will insert new row" - that is the problem: when there are two clients connected to the database you run into concurrency problems.
When you need the ids generated on the clients, use Guids - they are unique and hence it does not matter where they are generated. In MySQL, there is no datatype for guids, you can store them as CHAR(36).
