Question

What am I doing wrong in this sql:

Update products 
Set products.products_status = 0
Where products.products_id = products_to_categories.products_id And
products_to_categories.categories_id = 114

The error I am getting is: #1054 – Unknown column ‘products_to_categories.products_id’ in ‘where clause’ but that column does exist and I checked the spelling.

Answer 1

the reason for that is you didn’t specify the table products_to_categories on the UPDATE statement. You can join the table even with update statement though, try,

Update  products a
        INNER JOIN products_to_categories b
            ON a.products_id = b.products_id
Set a.products_status = 0
Where b.categories_id = 114
