mysql查询错误，尝试连接表

Question

Can anyone see why this code is returning an error?

    "SELECT
a.widget_id,
c.additional_widget_id
FROM
exp_widgets AS a,
INNER JOIN exp_widget_additional AS c ON a.entry_id = c.additional_entry_id
WHERE
a.template = 3
AND
c.additional_template_id = 3
AND
(a.entry_id = 6 OR c.additional_entry_id = 6)
";

Any help appreciated.

Answer 1

You have a rogue comma:

...
exp_widgets AS a,
INNER JOIN exp_widget_additional`
...

should be

...
exp_widgets AS a
INNER JOIN exp_widget_additional
...
