sql server - mysql equivalent data types

Question

I'm coming from a SQL Server background. What would the equivalent data types be for the following in MySQL:

NVARCHAR - provides support for international, multi-byte characters for all languages

NVARCHAR(max) - allows for very long text documents

Answer 1

Going by http://msdn.microsoft.com/en-us/library/ms186939.aspx, I would say that

VARCHAR(n) CHARSET ucs2

is the closest equivalent. But I don't see many people using this, more often people use:

VARCHAR(n) CHARSET utf8

As far as I am aware, both charactersets utf8 and ucs2 allow for the same characters, only the encoding is different. So either one should work, and I would probably go for the latter since it is used more often.

There are some limitations in MySQL's unicode support that may or may not apply to your use case. Please refer to http://dev.mysql.com/doc/refman/5.0/en/charset-unicode.html for more info on MySQL's unicode support.
