How to print SQL statement in codeigniter model

Question

I have a sql statement in my model,

I then say

$query = $this->db->query($sql, array(fields, fields1);

if ($query) {
    return true:
} else {         


        

Answer 1

You can display the ActiveRecord generated SQL:

Before the query runs:

$this->db->_compile_select(); 

And after it has run:

$this->db->last_query(); 

Answer 2

if you need a quick test on your query, this works great for me

echo $this->db->last_query(); die;

Answer 3

After trying without success to use _compiled_select() or get_compiled_select() I just printed the db object, and you can see the query there in the queries property.

Try it yourself:

var_dump( $this->db );

If you know you have only one query, you can print it directly:

echo $this->db->queries[0];

Answer 4

There is a new public method get_compiled_select that can print the query before running it. _compile_select is now protected therefore can not be used.

echo $this->db->get_compiled_select(); // before $this->db->get();

Answer 5

You can use this:

$this->db->last_query();

"Returns the last query that was run (the query string, not the result)."

Answer 6

I read all answers here, but cannot get

echo $this->db->get_compiled_select();

to work, It gave me error like,

Call to protected method CI_DB_active_record::_compile_select() from context 'Welcome'in controllers on line xx

So i removed protected from the below line from file \system\database\DB_active_rec.php and it worked

protected function _compile_select($select_override = FALSE)
