In Kohana 3, how do you figure out errors made during a query?
原标题:

I m using Kohana 3.

I m writing an update query, and it is working for everything except this one section.

If I do a var_dump() on the results of $db->execute() I get either a 1 or 0 to say it failed or not. It is failing in this example (returning 0).

How can I figure out what error is happening? It justs seems to be silenty failing at the time being. I tried doing echo mysql_error() but it didn t work, as I expected, as Kohana 3 s db library uses PDO I m pretty sure.

How can I figure out the error that has occurred?

Try executing this after calling $db->execute():

echo Database::instance()->last_query

Inside the Controller run the profiler:

$this->profiler = new Profiler;

And then after rendering View you ll see a list of queries that were executed. Try them out by connecting to the database or by using some software (like MySQL Query Browser).

Good luck!

It should throw an exception if it s a SQL error. You can catch this and echo it to get the error. See http://kerkness.ca/wiki/doku.php?id=crud_with_the_query_builder
