VARCHAR is a character data type used to store variable-length text. The maximum length is specified when the column is defined, depending on the database system.
VARCHAR is commonly used for business text fields because text values usually have different lengths. Choosing an appropriate data type is an important part of database design.
Employee names may have different lengths, so a VARCHAR column can store names without requiring every value to occupy the same fixed length.

EmployeeName VARCHAR(100),
Department VARCHAR(50)
);VARCHAR is commonly used for names, email addresses, city names, product names, codes, descriptions, and other variable-length text.
