Handle mysql errors using query builder

Thank you for the answer, but this is for simple queries. I am asking for query builder.

What Query Builder does is write query strings with the various parts provided by separate functions. Eventually, the database method -  _compile_select() - gathers all the input you provide with select(), from(), where(), etc and creates a string.

Inside db->get() it literally calls

PHP Code:

$this->query($this->_compile_select()); 


Inside the query() method a call to simple_query('your compiled select string here');

The moral of all this is that ultimately all Query Builder queries are "simple" queries,

Please feel free to use $this->db->error(); along with Query Builder.
