What is Smallint data type in SQL?

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.

What is Smallint type?

The SMALLINT data type stores small whole numbers that range from –32,767 to 32,767. The SMALLINT value is stored as a signed binary integer. Integer columns typically store counts, quantities, and so on. Because the SMALLINT data type requires only two bytes per value, arithmetic operations are performed efficiently.

Is Smallint used in SQL?

Exact-number data types that use integer data. To save space in the database, use the smallest data type that can reliably contain all possible values….In this article.

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

What is the difference between Int and Smallint?

INTEGER values have 32 bits and can represent whole numbers from –2 31–1 through 2 31–1. SMALLINT values have only 16 bits. They can represent whole numbers from –32,767 through 32,767. They take up little space (2 bytes per value for SMALLINT and 4 bytes per value for INTEGER).

Can Smallint be null?

The string must contain a valid string representation of a number. The result is the same number that would result from CAST(string-expression AS SMALLINT) . The result of the function is a small integer. The result can be null; if the argument is null, the result is the null value.

What is the size of an integer in SQL?

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 is the maximum integer in SQL Server?

The maximum values for an integer in SQL Server are: -2147483648 through 2147483647. And the byte size is 4 bytes. Other maximum values: BigInt: -9223372036854775808 through 9223372036854775807 (8 bytes) SmallInt: -32768 through 32767 (2 bytes)

What is int limit in SQL Server?

MAXINT or INT_MAX is the highest number that can be represented by a given integer data type. In SQL Server this number for the INT data type is 2,147,483,647.

What is the datatype of null in SQL Server?

Most, if not all, datatypes in SQL Server can be NULL; it’s just the representation of the absence of a value. SQL Server stores a “NULL Bitmap” for each row that tells it which columns are . If you were using NULL in a SELECT statement (example below) it defaults to a datatype of int. The data type of the column [EmptyColumn] will be int.
