What is data type SQL?
A data type is an attribute that specifies the type of data that the object can hold: integer data, character data, monetary data, date and time data, binary strings, and so on. SQL Server supplies a set of system data types that define all the types of data that can be used with SQL Server.
What type of data is number of days?
If a variable is measured by counting, such as the case if a researcher is counting the number of days a hospital patient has been hospitalized, the variable is on a ratio scale and is treated as a continuous variable.
What type of data is yes or no?
In research activities a YES/NO scale is nominal. It has no order and there is no distance between YES and NO. There are also highly sophisticated modelling techniques available for nominal data. An ordinal scale is next up the list in terms of power of measurement.
What data type is quantity?
The datatype quantity is for property values that describe quantities, in particular physical quantities such as time or distance. Values of this type consist of a numerical value followed by the name of a unit of measurement.
What data type is year in SQL?

Is real a data type?
A real data type is a data type used in a computer program to represent an approximation of a real number. Because the real numbers are not countable, computers cannot represent them exactly using a finite amount of information. Most often, a computer will use a rational approximation to a real number.
