inventory_stock_1 doest exist on magento 2.3

You need elevated permissions to use the CREATE ALGORITHM bit

This can and will stop an import in it's tracks.

Instead use this statement to create the view

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` )));

I got the solution for this, you need to create a view table inventory_stock_1 for your catalog in database.

Here is the command you need to run in your DB SQL. Make sure to update 3 things in below query dbusername, localhost, dbname.

CREATE ALGORITHM=UNDEFINED DEFINER=`dbusername`@`localhost` SQL SECURITY INVOKER 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 (`dbname`.`cataloginventory_stock_status` `legacy_stock_status` join `dbname`.`catalog_product_entity` `product` on((`legacy_stock_status`.`product_id` = `product`.`entity_id`)));
