Where can I do this? In which file should I change the line?

Where can I do this?

This is a SQL query, which you need to run in a database client (i.e. phpMyAdmin)

In which file should I change the line?

I am referring to the table name in line 13.

wp_wc_reserved_stock >> wp_ is the prefix and can differ in installations.

I can't do anything! The error remained. I'm doing something wrong. Please write more details.

I have got the table generated - however still seeing the message :
WooCommerce wp_wc_reserved_stock table creation failed. Does the wp user have CREATE privileges on the wordpress_somedb database?

To my knowledge this happens because these values do not match your environment ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_520_ci;
