Is there a function like _compile_select or get_co

问题:

Looks like _compile_select is deprecated and get_compiled_select is not added to 2.1.0. Are there any other functions like those two? And also I am curious. Is there any particular reason to not adding get_compiled_select() to Active Record and removing _compile_select?

回答1:

I've added get_compiled_select() to DB_active_rec.php and it seems to work without problem, but i wouldn't remove _compile_select() since it's used in many other methods.

The pull request for adding this method is here, with some other useful methods like:

• get_compiled_select()
• get_compiled_insert()
• get_compiled_update()
• get_compiled_delete()

if you want just the method, it's just this:

/**
 * Get SELECT query string
 *
 * Compiles a SELECT query string and returns the sql.
 *
 * @access  public
 * @param   string  the table name to select from (optional)
 * @param   boolean TRUE: resets AR values; FALSE: leave AR vaules alone
 * @return  string
 */
public function get_compiled_select($table = '', $reset = TRUE)
{
    if ($table != '')
    {
        $this->_track_aliases($table);
        $this->from($table);
    }

    $select =  $this->_compile_select();

    if ($reset === TRUE)
    {
        $this->_reset_select();
    }

    return $select;
}
