What is data type float?
The FLOAT data type stores double-precision floating-point numbers with up to 17 significant digits.
FLOAT corresponds to IEEE 4-byte floating-point, and to the double data type in C.
The range of values for the FLOAT data type is the same as the range of the C double data type on your computer..
What is a long data type?
Long is a data type used in programming languages, such as Java, C++, and C#. A constant or variable defined as long can store a single 64-bit signed integer. Because the long data type is signed, the possible integers range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, including 0. …

What data type is year in SQL?
MySQL displays YEAR values in YYYY format, with a range of 1901 to 2155 , and 0000 . YEAR accepts input values in a variety of formats: As 4-digit strings in the range ‘1901’ to ‘2155’ .
What are the 4 data types?
Some are used to store numbers, some are used to store text and some are used for much more complicated types of data ….The data types to know are:String (or str or text). … Character (or char). … Integer (or int). … Float (or Real). … Boolean (or bool).
What are the two data types?
Data types are divided into two groups:Primitive data types – includes byte , short , int , long , float , double , boolean and char.Non-primitive data types – such as String, Arrays and Classes (you will learn more about these in a later chapter)
What is data type for image in SQL?
For SQL Server In the “ImageSample” table, the image is stored in form of Varbinary(max) datatype, while in the “ImageSample1” table, the image is stored in form of Image datatype.
What are the 5 data types?
Common data types include:Integer.Floating-point number.Character.String.Boolean.
What are the four basic data types?
The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short, and long.
What is a real data type?
A ‘Real’ data type is numerical data which contains decimal numbers. It would be used when extra detail is required and a whole number would not provide enough information. Examples of where a ‘real’ data type is used can be seen below: Weight in Kg.
What is primary key SQL?
The PRIMARY KEY constraint uniquely identifies each record in a table. Primary keys must contain UNIQUE values, and cannot contain NULL values. A table can have only ONE primary key; and in the table, this primary key can consist of single or multiple columns (fields).
What are the SQL data types?

What are the data types in database?
Some common data types are as follows: integers, characters, strings, floating point numbers and arrays. More specific data types are as follows: varchar (variable character) formats, Boolean values, dates and timestamps.
What is data type float in SQL?
Use the SQL Server FLOAT data type to define columns, variables, and parameters storing floating-point numbers. By floating point, we mean, numbers that have no fixed decimal place. Consider using SQL FLOAT when working with scientific values.
Is money a data type in SQL?
The MONEY datatype in SQL server is intrinsically less precise than the DECIMAL datatype in calculations. SELECT 23/7 returns 3, since SQL Server has done integer division. If SQL Server performs calculations on the MONEY datatype, intermediate values are stored internally as MONEY datatypes.
