Question

short note on varchar

Answer 1

A varchar or Variable Character Field is a set of character data of indeterminate length. The term varchar refers to a data type of a field (or column) in a database management system which can hold letters and numbers. Varchar fields can be of any size up to a limit, which varies by databases: an Oracle 11g database has a limit of 4000 bytes,[1] a MySQL 5.7database has a limit of 65,535 bytes (for the entire row)[2] and Microsoft SQL Server 2008 has a limit of 8000 characters (unless varchar(max) is used, which has a maximum storage capacity of 2 gigabytes).[3]
