Common examples of standard SQL data types are Char, VarChar, Integer, and Numeric. The Char data type is for fixed-length character data. VarChar is for variable-length character data. Integer is for numeric data that are whole numbers only. Numeric is for numeric data that may include decimals. Char, VarChar, and Numeric must be qualified by a length specification to indicate the amount of storage space to be allocated for each data item. For example, Char(10) indicates fixed-length character data that is always stored as 10 characters.
