Way to explain all mysql select queries "Kohana Framework 3" model

Question

Using Kohana framework v3 I have created model with N methods using query builder. For example N-10% - use DB::select().
Is there any integrated functionality to do explain select for each method which use DB::select()?

I think to do this in this way:

Extend base query builder class and in Application folder remap execute() function with same code as was original, but add string which will write into mysql_log_of_selects.txt result of execution each select query with prepended EXPLAIN to it.
But what will propose you? Thanks!

Answer 1

Extend base query builder class and in Application folder remap execute() function with same code as was in original, but add "EXPLAIN " before each final query and result of it's execution save to log file.
