From what I fond on internet, I should be using NVARCHAR(max) to store some strings that contain up to 30k characters. I don't need to search through the strings, only store and retrieve it. The type TEXT seems obsolete, and VARCHAR isn't as friendly as NVARCHAR about Unicode, so I should be using NVARCHAR(max), right ?
Secondly, for now I'm using some sql database of a free webhosting service, i'm creating the structure via the phpmyadmin, and when creating columns it doesn't suggest NVARCHAR, only VARCHAR and other types. Is NVARCHAR still available, maybe with a DDL command ? The sql version is 5.5.32
Thanks and sorry if my questions are unclear, i'm kind of a newb
