When I try to update a table as follows
update Tisk set Barva = 'černobílý' where Barva = 'cernobílý';
the update works but Barva is still cernobílý. How can I fix it?

1What is the data type of the `Barva` column? – Zhorov Nov 01 '21 at 06:53

@Zhorov `nvarchar(50)`. From python code, I can set `barva` to `černobílý` – xralf Nov 01 '21 at 06:59

4Then you need to prefix the string literals with `N`: `set Barva = N'černobílý' where Barva = N'cernobílý'` – Zhorov Nov 01 '21 at 07:02

1You also need to check your column collation. It needs to accent-sensitive, if you want that this works reliably. – Tomalak Nov 01 '21 at 07:04
