SQL Server INT Data Types: BIGINT, INT, SMALLINT, TINYINT

In this tutorial, you have learned various SQL Server integer data types and how to use them to store integers in the database. Previously. SQL Server Data Types. Up Next. SQL Server Decimal.

What are the two major concerns for a database designer?
Two of the major concerns for a database designer are the size of the blank allocated in a field and the data that each entry takes up. INT and SMALLINT are data types that allow designers to place limits on both space size and data usage.
How many bytes can you have in a small integer?
To do this, you'll need SMALLINT. While INT lets you have up to 4 bytes per entry, SMALLINT limits you to 2. 2 x 8 = 16, so as a result, you only have a range of 65,536 (2^16) different numbers. Needless to say, that is still plenty, but may not suit every use.
What are the two fields in SQL?
To address this issue and limit the size of the blanks, SQL has a number of fields for numbers. Two of them will be discussed here - INT and SMALLINT.
How many bits are in 4 bytes?
Remember that each byte holds 8 bits of data, and that each bit can only be a one or a zero. To go down to the digital level, four bytes is 32 bits, which has two options, so INT gives you 2^32, or approximately 4.2 billion different values. For many of us, this will be more than enough room to represent the numbers needed.
What is structured query language?
As you may have heard by now, Structured Query Language (SQL) allows you to save data into fields using specified types, aptly named 'data types'. However, because SQL can manage truly massive databases, there comes a point where all that data is starting to really be a point of concern. If your database holds numbers and other quantitative data, it's not the size of the number that causes the storage requirements to jump, but instead the size of the blank.

What are the different types of integers in SQL Server?
SQL Server support standard SQL integer types including BIGINT, INT, SMALLINT, and TINYINT. The following table illustrates the range and storage of each integer type:
Is it a good practice to use the smallest integer data type that can reliably contain all possible values?
1 Byte. It is a good practice to use the smallest integer data type that can reliably contain all possible values. For example, to store the number of children in a family, TINYINT is sufficient because nowadays no one could have more than 255 children.
How many bytes does a tinyint use?
You can store the number 1 in all 4, but a bigint will use 8 bytes, while a tinyint will use 1 byte.
Is integer datatype overkill?
When it gets to real world usage of these datatypes, it is very important that you understand that using certain integer types could just be an overkill or under used. For example, using integer datatype for employeeCount in a table say employee could be an overkill since it supports a range of integer values from ~ negative 2 billion to positive 2 billion or zero to approximately 4 billion (unsigned). So, even if you consider one of the US biggest employer such as Walmart with roughly about 2.2 million employees using an integer datatype for the employeeCount column would be unnecessary. In such a case you use mediumint (that supports from 0 to 16 million (unsigned)) for example. Having said that if your range is expected to be unusually large you might consider bigint which as you can see from Daniel's notes supports a range larger than I care to decipher.
What is SQL Server int?
SQL Server int (or integer) data types represent mathematical integer numbers or whole numbers. They include both negative & positive numbers. But fractions are not allowed. The SQL Server supports four types of integer data types each of different sizes. They are tinyint, smallint, int & bigInt.
What is the max value of INT?
Use BigInt only you expect the column value takes a huge number (i.e., greater than 2,147, 483,647 which is the max value of INT data type). BigInt takes double the space than that of INT
How many data types can a tinyint column hold?
Always use the smallest data type that suits the requirements of the column. For Example for an age, column tinyint is more than sufficient as it can store up to 255.
What happens when you divide an integer by an integer?
Dividing the integer by integer, will keep the result as integer. i.e.. you will loose the precision.
