Question

When there is an error with your sql statement in codeigniter you get a message a bit like this:-

 A Database Error Occurred

Error Number: 1096

- some sql -

Filename: \system\database\DB_driver.php

Line Number: 334

Which is all well and good but when you’ve got lots of statements running for a single page it would help to know which line of code generated the query.

How do I get name of the model and method (or the filename) which generated the query?

Answer 1

I’m answering my own question here because I found a quick and dirty solution which works for debugging purposes. I highly recommend leaving CI system files in tact, this should only be used for debugging. I might write an extension for CI to do this when I’ve got time.

Solution for CI 2:-

Go and edit system\database\DB_driver.php and add the following code on line 321:-

echo "<pre>";
debug_print_backtrace();
echo "</pre>";
