Question

I am trying to run this query but doesn’t run

SELECT ng.parent_id, ng.tab, ng.post_id, ng.ORDER, ng.cluster_key, pd.id, pd.slug, pd.link_text, pd.parent
FROM `ecom_navigation` AS ng, `ecom_page_data` AS pd
WHERE ng.cluster_key = 'primary'
AND ng.tab = '0'
AND ng.parent_id = '1'pd.id = ng.post_id
ORDER BY ng.order

and getting error

You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ‘pd.id = ng.post_id ORDER BY ng.order’ at line 1

i’ve tried `ng.order` and `ng`.`order` but still cant seem to get it to run.

Any help is much appreciated

I think you’re just missing an and:

AND ng.parent_id = '1'pd.id = ng.post_id

should probably be:

AND ng.parent_id = '1'
AND pd.id = ng.post_id

Or better, put the join condition in the join (and don’t quote your numbers unless they really are strings):

SELECT ng.parent_id, ng.tab, ng.post_id, ng.ORDER, ng.cluster_key, pd.id, pd.slug, pd.link_text, pd.parent
FROM `ecom_navigation` AS ng join `ecom_page_data` AS pd on ng.post_id = pd.id
WHERE ng.cluster_key = 'primary'
AND ng.tab = 0        -- Leave the quotes on if tab is a string
AND ng.parent_id = 1  -- Leave the quotes on if parent_id is a string
ORDER BY ng.order
