What is difference between integer and decimal?
Integer: Accepts positive and negative whole numbers, but not decimals or fractions. It is often used to count the number of items in invoices or inventory forms, or to collect a reading on a piece of machinery. Decimal: Accepts any number with decimal places.
Which data type is also called a user defined data type?
A structured type is a user-defined data type that has a structure that is defined in the database. It contains a sequence of named attributes, each of which has a data type. A structured type also includes a set of method specifications.
