This is query to get all categories available in database.
$sql = "SELECT cp.category_id AS category_id, GROUP_CONCAT(cd1.name ORDER BY cp.level SEPARATOR ' > ') AS name, c1.parent_id, c1.sort_order FROM " . DB_PREFIX . "category_path cp LEFT JOIN " . DB_PREFIX . "category c1 ON (cp.category_id = c1.category_id) LEFT JOIN " . DB_PREFIX . "category c2 ON (cp.path_id = c2.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd1 ON (cp.path_id = cd1.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd2 ON (cp.category_id = cd2.category_id) WHERE cd1.language_id = '" . (int)$this->config->get('config_language_id') . "' AND cd2.language_id = '" . (int)$this->config->get('config_language_id') . "'";
So, i am trying to get only that categories listed in rma_mapping_category(this has category_id column)
so i tried this, but syntax got wrong by adding this(AND rma_mapping_category rma)… /////////////////////
$sqs = "SELECT cp.category_id AS category_id, GROUP_CONCAT(cd1.name ORDER BY cp.level SEPARATOR ' > ') AS name, c1.parent_id, c1.sort_order FROM " . DB_PREFIX . "category_path cp AND rma_mapping_category rma LEFT JOIN " . DB_PREFIX . "category c1 ON (cp.category_id = c1.category_id) LEFT JOIN " . DB_PREFIX . "category c2 ON (cp.path_id = c2.category_id) -> LEFT JOIN " . DB_PREFIX . "category c3 ON (rma.categoryid = c3.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd1 ON (cp.path_id = cd1.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd2 ON (cp.category_id = cd2.category_id) WHERE cd1.language_id = '" . (int)$this->config->get('config_language_id') . "' AND cd2.language_id = '" . (int)$this->config->get('config_language_id') . "'";
Also tried this… ////////////////////// by this i am getting all categories rather than just rma_mapping_category
Same result as First Query.
$sqs = "SELECT cp.category_id AS category_id, GROUP_CONCAT(cd1.name ORDER BY cp.level SEPARATOR ' > ') AS name, c1.parent_id, c1.sort_order FROM " . DB_PREFIX . "category_path cp LEFT JOIN " . DB_PREFIX . "category c1 ON (cp.category_id = c1.category_id) LEFT JOIN " . DB_PREFIX . "category c2 ON (cp.path_id = c2.category_id) LEFT JOIN rma_mapping_category rma ON (cp.category_id = rma.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd1 ON (cp.path_id = cd1.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd2 ON (cp.category_id = cd2.category_id) WHERE cd1.language_id = '" . (int)$this->config->get('config_language_id') . "' AND cd2.language_id = '" . (int)$this->config->get('config_language_id') . "'";
Any suggestion, what i sould try? Any help will be appreciated.

Answer
Query worked as expected after adding ==
INNER JOIN rma_mapping_category rma ON (cp.category_id = rma.category_id)
like below
$sql = "SELECT cp.category_id AS category_id, GROUP_CONCAT(cd1.name ORDER BY cp.level SEPARATOR ' > ') AS name, c1.parent_id, rma.type_id, c1.sort_order FROM " . DB_PREFIX . "category_path cp LEFT JOIN " . DB_PREFIX . "category c1 ON (cp.category_id = c1.category_id) LEFT JOIN " . DB_PREFIX . "category c2 ON (cp.path_id = c2.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd1 ON (cp.path_id = cd1.category_id) LEFT JOIN " . DB_PREFIX . "category_description cd2 ON (cp.category_id = cd2.category_id) INNER JOIN rma_mapping_category rma ON (cp.category_id = rma.category_id) WHERE cd1.language_id = '" . (int)$this->config->get('config_language_id') . "' AND cd2.language_id = '" . (int)$this->config->get('config_language_id') . "'";
