Question

I have a table named application_user which have a field named id. Another table named voucher_info which has a field named maker_id. Now I want to LEFT JOIN the application_user table with voucher_info table using maker_id with id ? But this error is shown instead:

Error Code: 1054
            Unknown column 'application_user.id' in 'on clause'

Can anyone please help me on this please ? Here is my code below :

LEFT JOIN application_user AS maker
    ON(voucher_info.maker_id = application_user.id)

Answer 1

Change it to

ON (voucher_info.maker_id = maker.id)

Once you alias a table, you can only reference it by the alias.
