magento product visibility

Is there a way by mysql to set ALL product visibility to catalog, sear开发者_如何学Cch?

open up the eav_attribute table and find the row where attribute_code = visibility. Take note of the attribute_id, most likely it will be 85. Also take note that backend_type = int. This tells you that the attribute is stored in catalog_product_entity_int. So, now you can run:

update `catalog_product_entity_int` set value = 4 where attribute_id = 85

(assuming of course that the attribute_id was 85!)

Make sure you backup the database before you run it.
