Magento catalog_category_flat_store_1 does not exist

Question

I have an existing store running Magento CE 1.7. Suddenly from today morning (without any code updates), I am receiving the following error -

a:5:{i:0;s:111:"SQLSTATE[42S02]: Base table or view not found: 1146 Table 'XXXXXX.catalog_category_flat_store_1' doesn't exist";i:1;s:5914:"#0 /var/www/lib/Varien/Db/Statement/Pdo/Mysql.php(110): Zend_Db_Statement_Pdo->_execute(Array)

I can see that the table actually exists in the Database and can be accessed from the server. However, the error report is indicating that its not found.

I have so far,

-- Cleared Cache

-- Rebuilt indexes

-- Removed the table and rebuilt the index again, so that it gets created automatically and it does.

Can anyone please throw some light on this??

Answer 1

I've had this happen before. This usually occurs when the database crashes during an indexing process, and the table gets corrupted or deleted.

I do as follows:

1. Drop catalog_category_flat_store_1 from the database if it exists (delete it completely).

2. Install a new instance of Magento on a new database (or use another pre-existing Magento database)

3. From the new (or existing Magento database), clone the catalog_category_flat_store_1 to your Magento database (the one that is having the error).

4. Reindex your site - specifically the Category Flat Data index.

I had the same problem yesterday night, but the table seems to exist and used/updated as normally today. Maybe it has crashed and mysql fixed it automatically (but I am not sure of this), but it functions normally again.

This issue can be resolved by reindexing.

You have to run Catalog Category Flat Reindex .

You can do this from the Magento backend: System -> Index Management or via ssh.

Using SSH go to you shell directory and run php -f indexer.php -- -reindex catalog_category_flat

Hope this helps you.
