显示MySQL错误Joomla 2.5

Question

How can I display if there is any error after executing last query by query() or execute() in Joomla 2.5?

CUrrently I am using var_dump($wsr_db_object->stderr(true)); but this does not show MySQL errors. It only helps you that query was executed or not?

Edit:

Here is how I am running my

    $rw_db_object->setQuery($insert_rw_cats);
    $rw_db_object->query();
    var_dump($wsr_db_object->stderr(true));

Answer 1

Joomla has a built in dump method like so:

$query->dump();

When writing your queries, please refer to the Joomla documentation

Hope this helps

Update:

$rw_db_object->setQuery($insert_rw_cats);
$rw_db_object->query();
$rw_db_object->dump();
