Magento 1.7.0 General error: 1005 Can't create table 'db_name.catalog_category_flat_store_1' (errno: 150)'

Question

I'm trying to manually reindex my categories via SSH since it doesn't work in the Magento Admin panel.

Here's what I've done and checked so far from suggestions I found on the net:

• Cleared tmp folder
• Cleared var/locks folder
• Deleted catalog_category_flat entry in db (there was no catalog_category_flat_1)
• Server isn't full - there's 2gb of hosting space left
• User has all access rights for the database
• Used ssh to reindex (php shell/indexer.php --reindex catalog_category_flat)

When I try to reindex via ssh, this is the error I get:

/home/mysitehere/public_html/shell$ php indexer.php --reindex catalog_category_flat

Any help will be greatly appreciated. I've been stuck on this for a few days now.

Answer 1

Problem solved.

The tables were MyISAM instead of InnoDB.

Answer 2

The table is not created because that error 150 MySQL occurs:

http://forums.mysql.com/read.php?20,398982,399084#msg-399084

I dumped the foreign constraint key on this table from a Magento database:

ALTER TABLE `catalog_product_flat_1`
   ADD CONSTRAINT `FK_CAT_PRD_FLAT_1_ENTT_ID_CAT_PRD_ENTT_ENTT_ID` FOREIGN KEY 
       (`entity_id`) REFERENCES `catalog_product_entity` (`entity_id`) ON DELETE CASCADE ON UPDATE CASCADE;

Both columns entity_id in both tables should be the same: https://stackoverflow.com/questions/1085001/mysql-creating-table-with-fk-error-errno-150 . You either modified column entity_id on table catalog_product_entity or Magento doesn't generate the table using DDL statements correctly.
