Data should be stored in Unicode data types; for example in SQL server uses nchar, nvarchar, and nvarchar(max); instead of their non-Unicode equivalents, char, varchar, and text. UN-2 Another example, a SQL Server column of the data type nvarchar(255) (or smaller) is imported or link...
Thetext in rowoption will be removed in a future version of SQL Server. Avoid using this option in new development work, and plan to modify applications that currently usetext in row. We recommend that you store large data by using the varchar(max), nvarchar(max), or varbinary(max) data...
For example, in a column defined as nchar(10), the Database Engine can store 10 characters that use one byte-pair (Unicode range 0 to 65,535), but fewer than 10 characters when using two byte-pairs (Unicode range 65,536 to 1,114,111). For more information about Unicode storage a...

You must specify a maximum length for a VARCHAR2 column. This maximum must be at least 1 byte, although the actual string stored is permitted to be a zero-length string (''). You can use the CHAR qualifier, for example VARCHAR2(10 CHAR), to give the maximum length in characters inste...
