(1 row(s) affected) SELECT * FROM t WHERE c=N 'DETAIL' collate Turkish_CI_AI SELECT * FROM t WHERE c=N 'detail' collate Turkish_CI_AI Turkish CI_AI collation should return 2 rows (case insensitive, accent insensitive) The spanish language doesn't consider the letter Г± (n with a tilde) to beВ an accented versionВ of the letter n. For example, most accent insensitive collations will consider the two letters nВ and the spanish Г± to be equal but a spanish collation won't even if you specify that it must be an accent unsensitiveВ like You don't have the same problem here with yourВ hungarian letter: every latin languages will expect the same transformation so there is no problem here whatever the collation you will be using. Undotted I to the loer dotted i but a turkish collation won't. So, most latin collations will translate the upper For example, someone who doesn't speak (or doesn't deal with) turkish willД®xpect that the upper case undotted I will be translated into the dotted if if apply the lower case transformation but someone dealing with the turkish language won't have theВ same expectation. The problem here is that these rules try to follow the normal expectations of everyone but these expectations can vary from person to person depending on the language used. Than the simple character by character comparaison and can involve multiple characters on each side for each step.) However, when you specify a collation like a turkish or hungarian collation -В with or without case and accent sensitivities - you specify a set of rules for comparing and transforming these letters between themselves. To unicode, the lower accented hungarian letter is a different from its upper case counterpart than it is Unicode is not a collation, it's a character set and by itsefl, it knows nothing about lowercase, uppercase and letters with or without accent.

There are a few collations that does not have a code page, and therefore only can be used with nvarchar. RГ¤ksmГ¶rgГҐs, you would find that it would be garbled, because CP1251 does not have ГҐ.

If you would install a server with Hungarian_CI_AS as the collation, you would find that your varchar example would work just fine, because Hungarian_CI_AS uses CP1251 as the code page, and the code pages is good for languages in eastern Central Europe.ДЄs it happens, the Swedish example would also work, if you would try the classic Swedish word in this context, This collation uses CP1252 for varchar, and this code page is good for most Germanic and Romance languages, as well as a few more. I would assume that your collation is SQL_Latin1_General_CP1_CI_AS, since this is the default for installations You can store text for almost all languages in varchar, but you do need to have a collation fitted for these languages. SQL Server 2008 default collation, Hungarian, Latvian, Turkish, Polish and some other languages require nvarchar storage due to real (not zero padded) UNICODE letters. But Swedish does not require nvarchar, it can be stored in varchar.ДЄssuming U.S. You can put Swedish text into UNICODE nvarchar and still works.

Table of UNICODE codes, for Czech, Hungarian, Polish, Scandinavian and some other Central European Languages. O UNICODE (2 bytes, also called special characters) like Swedish alphabet - ASCII and Extended ASCII (Г… Г„ Г– ) - varchar DECLARE varchar(32) = 'ABCDEFGHIJKLMNOPQRSTUVXYZГ…Г„Г–' On the other hand to represent the JapaneseВ or Chinese letters, you need UNICODE nvarchar. Yet, that does not change the fact thatДЎ byte (varchar) is sufficient to represent the Latin alphabet. You can also move it to 5 bytes, pad it with zerosВ and call it something else. If you move ASCII A into 2 bytes, it is still ASCII A in UNICODE representation. I am afraid Erland you made up your own definition.
