What is integer data type in SQL?
Integer data types hold numbers that are whole, or without a decimal point. (In Latin, integer means whole.) ANSI SQL defines SMALLINT , INTEGER , and BIGINT as integer data types. The difference between these types is the size of the number that they can store.
What is the range of integer type?
-2,147,483,647 to 2,147,483,647
The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. The number 2,147,483,648 is a reserved value and cannot be used. The INTEGER value is stored as a signed binary integer and is typically used to store counts, quantities, and so on.
How do I limit integers in SQL?
If you want to limit the range of an integer column you can use a check constraint: create table some_table ( phone_number integer not null check (phone_number between 0 and 9999999999) );
What are the 5 my SQL integer types?
2 Integer Types (Exact Value) – INTEGER, INT, SMALLINT, TINYINT, MEDIUMINT, BIGINT. MySQL supports the SQL standard integer types INTEGER (or INT ) and SMALLINT . As an extension to the standard, MySQL also supports the integer types TINYINT , MEDIUMINT , and BIGINT .
What type of data type is integer?
integral data type
In computer science, an integer is a datum of integral data type, a data type that represents some range of mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits (bits).
Is integer in SQL Server?
The int data type is the primary integer data type in SQL Server. The bigint data type is intended for use when integer values might exceed the range that is supported by the int data type.

What is the range of int in MySQL?
-2147483648 to 2147483647
The signed range of INT is from -2147483648 to 2147483647 and the unsigned range is from 0 to 4294967295. You can specify signed or unsigned int in the column definition. The size parameter specifies the maximum length of the number which is 255.
