Write the sql judgment of SqlServer today (case when a.[sales/sales]='sales out of stock' then '0' when a.[sales/sales out]='sales out of stock' then '1' else a.[sales /pin back] end) aa
It turned out that I couldn't judge whether it was life or death, and after consulting an old colleague, I learned that I needed to add N, and I was confused about what N???????
as follows
(case when a.[Sales/Return]=N'Sales out of the warehouse' then '0' when a.[Sales/Returns]=N'Sales out of the warehouse' then '1' else a.[Sales/Returns] end) aa
Sure enough, I don't understand the world of sqlserver
