SQL : Primary Key and Unique Key

You can use UNIQUE constraints to make sure that no duplicate values are entered in specific columns that do not participate in a primary key.

Multiple UNIQUE constraints can be defined on a table, whereas only one PRIMARY KEY constraint can be defined on a table. Also, unlike PRIMARY KEY...

SQL : char, nchar, nchar, nvarchar

nchar and nvarchar can store Unicode characters. char and varchar cannot store Unicode characters. char and nchar are fixed-length which will reserve storage space for number of characters you specify even if you don't use up all that space. varchar and nvarchar are variable-length which will only use up spaces for the characters you store. It will not reserve storage like char or nchar. nchar and nvarchar will take up twice as much storage space, so it may be wise to use them only if you need Unicode support. You can use char when the data entries...
