These are just scratches/notes for my work with Prestashop

select id_product, reference from ps_product where reference like '9254050' limit 10;

Uppercase first letter only on string, and lowercase the others (remove any spaces infront or at the end)
select name, concat(upper(left(name,1)),lower(substring(name,2,length(name)))) from ps_product_lang where id_product = 22285 limit 10;

update ps_product_lang set name = concat(upper(left(trim(name),1)),lower(substring(trim(name),2,length(trim(name)))));

Create copy of table / duplicate table (select into kind of)

create table tobias_ps_product_lang_20211107 as select * from ps_product_lang;

create table tobias_ps_product_shop_20220113 as select id_product, id_shop, price, wholesale_price from ps_product_shop;

select id_product, id_shop, price, wholesale_price from ps_product_shop;
