Int is a data type in the database – an integer (whole number) . What it means depends on the database you use – in SQL Server the 4 specifies the field precision. However, this will always be the size of an int in SQL Server. It can holdvalues between -2,147,483,648 and 2,147,483,647.
What does int () do in SQL?
Use the SQL Server INT data type to define columns, variables, and parameters storing whole numbers . The INT data type stores a number in the range -2,147,483,648 to 2,147,483,647. If you need to store a larger integer value, consider using BIGINT.
How do you write an int in SQL?
| Data type Range Storage | INT -2 31 (-2,147,483,648) to 2 31 -1 (2,147,483,647) 4 Bytes | SMALLINT -2 15 (-32,768) to 2 15 -1 (32,767) 2 Bytes | TINYINT 0 to 255 1 Byte |

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 difference between int and Bigint in SQL?
The int type takes 4 byte signed integer i.e. 32 bits ( 2 32 values can be stored). The BigInt type takes 8 byte signed integer i.e. 64 bits (2 64 values can be stored).
What is a big int?
A big integer is a binary integer that has a precision of 63 bits . The BIGINT data type can represent 63-bit integers and is compatible with all numeric data types. The BIGINT function returns a big integer representation of a number or a string representation of a number.
How do I limit int 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 is big INT in SQL?
The BigInt data type in SQL Server is the 64-bit representation of an integer . It takes up 8 bytes of storage. It can range from -2^63 (-9,223,372,036,854,775,808) to 2^63 (9,223,372,036,854,775,807). ... The BigInt was used for the audit id that was used for session data in case authentication failed.
What is means by INT 11 in MySQL?
In MySQL integer int(11) has size is 4 bytes which equals 32 bit . Signed value is : – 2^(32-1) to 0 to 2^(32-1)-1 = -2147483648 to 0 to 2147483647.
What does Int 4 mean in MySQL?
For example, INT(4) specifies an INT with a display width of four digits . This optional display width may be used by applications to display integer values having a width less than the width specified for the column by left-padding them with spaces.
What are the five data types?
- String (or str or text). Used for a combination of any characters that appear on a keyboard, such as letters, numbers and symbols.
- Character (or char). Used for single letters.
- Integer (or int). Used for whole numbers.
- Float (or Real). ...
- Boolean (or bool).
Can int be negative SQL?
In MySQL, INT stands for the integer that is a whole number. An integer can be written without a fractional component e.g., 1, 100, 4, -10, and it cannot be 1.2, 5/3, etc. An integer can be zero, positive, and negative . MySQL supports all standard SQL integer types INTEGER or INT and SMALLINT .
What is data type int?
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. bigint fits between smallmoney and int in the data type precedence chart.
Which is bigger BigInt or INT?
| INT BIGINT | Storage Size 4 Bytes 8 Bytes | Minimum Value -2,147,483,648 (-2^31) -9,223,372,036,854,775,808 (-2^63) |

What does BigInt 20 mean?
It just means that when the data is displayed, if it uses less than 20 digits it will be left-padded with zeros . 2^64 is the hard limit for the BIGINT type, and has 20 digits itself, hence BIGINT(20) just means everything less than 10^20 will be left-padded with spaces on display.
What is small INT?
The SMALLINT data type stores small whole numbers that range from –32,767 to 32,767 . The maximum negative number, –32,768, is a reserved value and cannot be used. The SMALLINT value is stored as a signed binary integer. Integer columns typically store counts, quantities, and so on.
