MySQL unknown column (is in table) -


my table structure:

inventory_items:

create table `inventory_items` (  `id` int(10) unsigned not null auto_increment,  `name` varchar(50) default null comment 'usually used invoice number',  `vendor_id` int(10) not null default '1',  `item_type_id` int(10) unsigned default null,  `item_model_id` int(10) unsigned default null,  `condition_id` int(10) unsigned default null,  `item_functionality_id` int(10) unsigned default null,  `color_id` int(10) unsigned default null,  `quantity` int(10) unsigned default null,  `original_qty` int(10) default null,  `note` text,  `zone_id` int(10) unsigned default null,  `rack_id` int(10) unsigned default null,  `shelf_id` int(10) unsigned default null,  `bin_id` int(10) unsigned default null,  `status` char(1) default null comment '1:checkedin;2:transferred',  `reserve` tinyint(1) not null default '0',  `log` text,  `user_id` int(10) unsigned default null,  `created` datetime default null,  `modified` datetime default null,  `item_manu_model_id` int(11) not null default '0',  `cdma_carrier_id` int(11) default '0',  primary key (`id`) ) engine=innodb auto_increment=45334 default charset=latin1

my sql-query:

select inventory_items.id,        conditions.`name`,        item_models.`name`   inventory_items,        sorting_reports        inner join item_models                on inventory_items.item_model_id = item_models.id        inner join conditions                on inventory_items.condition_id = conditions.id  inventory_items.item_model_id = 1111        , inventory_items.condition_id = 10        , inventory_items.id = 20        , ( ( inventory_items.zone_id = 21 )               or ( inventory_items.rack_id = 175 ) )        , sorting_reports.id != 0

and following error:

[err] 1054 - unknown column 'inventory_items.item_model_id' in 'on clause'

the column existing.... :(

short answer: mixing join types. use inner join or , notation, not both. reason: compiler attempts complete inner join statements first before generating possibly large cartesian on , type join. @ time join attempted, has no knowledge of value in question. if mean cross join state , problem should go away.

more on can found: what difference between using cross join , putting comma between 2 tables?

select inventory_items.id,        conditions.`name`,        item_models.`name`   inventory_items         cross join sorting_reports        inner join item_models                on inventory_items.item_model_id = item_models.id        inner join conditions                on inventory_items.condition_id = conditions.id  inventory_items.item_model_id = 1111        , inventory_items.condition_id = 10        , inventory_items.id = 20        , ( ( inventory_items.zone_id = 21 )               or ( inventory_items.rack_id = 175 ) )        , sorting_reports.id != 0
