What are the MySQL Equivalents of SQL Server\'s NVARCHAR and NVARCHAR(max) Data Types?

MySQL Equivalents of SQL Server Data Types

Question: As a former SQL Server user, you may be wondering about the equivalent data types in MySQL for the following:

• NVARCHAR: Provides support for international, multi-byte characters for all languages.
• NVARCHAR(max): Allows for very long text documents.

Answer:

Based on the information provided in Microsoft's documentation, the nearest equivalent to NVARCHAR in MySQL would be:

VARCHAR(n) CHARSET ucs2

However, it's more common to use:

VARCHAR(n) CHARSET utf8

UTF8 and UCS2 character sets support the same characters but with different encodings. Either should work, with UTF8 being the more widely used option.

It's important to note that MySQL's Unicode support has certain limitations. For instance, Unicode handling for indexes is not as robust as in SQL Server. Refer to MySQL's documentation on Unicode support for more details.
