Datatyp char

Char is a fixed width data type while Varchar is a variable-length dataType. Even though the character ‘A’ is only one character, the number of bytes of the column is fixed which is three. In this tutorial, you have learned how to use the SQL Server CHAR data type to store fixed-length, non-Unicode character strings in the database. In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support basic data types of integer numbers (of varying sizes), floating-point numbers (which approximate real numbers), characters and These are called datatypes.
