How to batch Delete products in magento background

How does magento batch Delete products? Anyone who has used magento knows that it is very slow to delete products in batches in the magento background. 30 products cannot be deleted in one minute. Select
A time get out 504 error may occur when multiple products Perform Batch deletion.
. This is because each product has many attributes and is associated with nearly 30 tables in the database. Each time a product is deleted, the database must query more than 30 tables, therefore, the more products that are deleted in batches, the more expensive
The longer the time, the more likely the server will time out.
The following describes a simple method to delete nearly a thousand products within 3 seconds (it is best to back up the database before doing so, I tested it in magento1.4): First open your magento database, select SQL and copy the following code to run the SQL query in the database magento:

Truncate table 'catalog _ product_bundle_option ';
Truncate table 'catalog _ product_bundle_option_value ';
Truncate table 'catalog _ product_bundle_selection ';
Truncate table 'catalog _ product_entity_datetime ';
Truncate table 'catalog _ product_entity_decimal ';
Truncate table 'catalog _ product_entity_gallery ';
Truncate table 'catalog _ product_entity_int ';
Truncate table 'catalog _ product_entity_media_gallery ';
Truncate table 'catalog _ product_entity_media_gallery_value ';
Truncate table 'catalog _ product_entity_text ';
Truncate table 'catalog _ product_entity_tier_price ';
Truncate table 'catalog _ product_entity_varchar ';
Truncate table 'catalog _ product_link ';
Truncate table 'catalog _ product_link_attribute ';
Truncate table 'catalog _ product_link_attribute_decimal ';
Truncate table 'catalog _ product_link_attribute_int ';
Truncate table 'catalog _ product_link_attribute_varchar ';
Truncate table 'catalog _ product_link_type ';
Truncate table 'catalog _ product_option ';
Truncate table 'catalog _ product_option_price ';
Truncate table 'catalog _ product_option_title ';
Truncate table 'catalog _ product_option_type_price ';
Truncate table 'catalog _ product_option_type_title ';
Truncate table 'catalog _ product_option_type_value ';
Truncate table 'catalog _ product_super_attribute ';
Truncate table 'catalog _ product_super_attribute_label ';
Truncate table 'catalog _ product_super_attribute_pricing ';
Truncate table 'catalog _ product_super_link ';
Truncate table 'catalog _ product_enabled_index ';
Truncate table 'catalog _ product_website ';
Truncate table 'catalog _ product_entity ';
Truncate table 'cataloginventory _ stock ';
Truncate table 'cataloginventory _ stock_item ';
Truncate table 'cataloginventory _ stock_status ';
Insert
Into 'catalog _ product_link_type '('link _ type_id', 'code') Values
(1, 'relation'), (2, 'bundle'), (3, 'super'), (4, 'Up _ login'), (5, 'Cross _ Region ');
Insert
Into
'Catalog _ product_link_attribute '('product _ link_attribute_id', 'link _ type_id ', 'product _ link_attribute_code', 'Data _ type ')
Values
(, 'Qty ', 'decimal'), (, 'position', 'int'), (, 'position', 'int, 'position', 'int'), (6, 1, 'qty ', 'decimal'), (, 'position', 'int'), (, 'qty ', 'decimal ');

Insert into 'cataloginventory _ stock' ('Stock _ id', 'stock _ name') values (1, 'default ');

Soon, the records of all products and products were deleted in just a few seconds, saving a lot of valuable time.
In addition, this article describes how to delete a product category directory through a database:
Copy the following code to run the SQL query in the database magento.
Truncate table 'catalog _ category_entity ';
Truncate table 'catalog _ category_entity_datetime ';
Truncate table 'catalog _ category_entity_decimal ';
Truncate table 'catalog _ category_entity_int ';
Truncate table 'catalog _ category_entity_text ';
Truncate table 'catalog _ category_entity_varchar ';
Truncate table 'catalog _ category_product '; <H2> </H2> Truncate table 'catalog _ category_product_index ';
Insert
Into
'Catalog _ category_entit' ('entity _ id', 'entity _ type_id ', 'attribute _ set_id', 'parent _ id', 'created _ ', 'updated _ at', 'path', 'position', 'level', 'Children _ count ')
Values (0000, 2009, '2017-00-00 00:00:00 ', '2017-02-20
00:25:34 ', '1', 2009, 1), (2009,-02-20 00:25:34', '2017-02-20
00:25:34 ', '123', 1/2, 0 );
Insert
'Catalog _ category_entity_int '('value _ id', 'entity _ type_id', 'attribute _ id', 'store _ id', 'entity _ id', 'value ')
Values );
Insert
'Catalog _ category_entity_varchar '('value _ id', 'entity _ type_id', 'attribute _ id', 'store _ id', 'entity _ id', 'value ')
Values (, 1, 'root
Catalog '), (, 1, 'root-catalog'), (, 2, 'default
CATEGORY '), (, 2, 'products'), (, 2, 'default-category ');

In this way, the directory and related information are quickly deleted.
