When I try to rollback using a sql dump file created in Magento 2.3.0, I get the following error:
Table 'inventory_stock_1' was not locked with LOCK TABLES
I'm answering my own question because I spent all morning on this and thought it might be helpful to someone else.
The issue is that with 2.3.0
inventory_stock_1 is no longer a table, it's now a view. That's all fine except that the code creating the sql backup still wants to treat it like a table. Hopefully this gets fixed in the next version.
My fix was to directly edit the sql dump file using a text editor. The entire block related to this table, starting from this line:
-- -- Table structure for table `inventory_stock_1` -- DROP TABLE IF EXISTS `inventory_stock_1`;
all the way to this line:
/*!40000 ALTER TABLE `inventory_stock_1` ENABLE KEYS */; UNLOCK TABLES;
It all needs to be replaced with a create view query instead. Delete all those lines, and in their place include:
CREATE OR REPLACE VIEW `inventory_stock_1` AS select distinct `legacy_stock_status`.`product_id` AS `product_id`, `legacy_stock_status`.`website_id` AS `website_id`, `legacy_stock_status`.`stock_id` AS `stock_id`, `legacy_stock_status`.`qty` AS `quantity`, `legacy_stock_status`.`stock_status` AS `is_salable`, `product`.`sku` AS `sku` from ( `cataloginventory_stock_status` `legacy_stock_status` join `catalog_product_entity` `product` on (( `legacy_stock_status`.`product_id` = `product`.`entity_id` )));
Save the dump file and try the rollback again.
I hope this helps!
