Unicode strings
Unicode strings have a format similar to character strings but are preceded
by an N identifier (N stands for National Language in the SQL-92 standard).
The N prefix must be uppercase. For example, 'Michl' is a character constan
t while N'Michl' is a Unicode constant. Unicode constants are interpreted a
s Unicode data, and are not evaluated using a code page. Unicode constants d
o have a collation, which primarily controls comparisons and case sensitivit
y. Unicode constants are assigned the default collation of the current datab
ase, unless the COLLATE clause is used to specify a collation. Unicode data
is stored using two bytes per character, as opposed to one byte per characte
r for character data. For more information, see Using Unicode Data.
Unicode string constants support enhanced collations.
