## 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 integer SQL Server?

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.

## Which is integer data type?

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 you specify an integer in SQL?

**SQL Server Integers example**

- CREATE TABLE test.sql_server_integers ( bigint_col bigint, int_col INT, smallint_col SMALLINT, tinyint_col tinyint ); …
- INSERT INTO test.sql_server_integers ( bigint_col, int_col, smallint_col, tinyint_col ) VALUES ( 9223372036854775807, 2147483647, 32767, 255 );

## What is character data type?

The CHAR data type **stores character data in a fixed-length field**. Data can be a string of single-byte or multibyte letters, numbers, and other characters that are supported by the code set of your database locale. … The size of a CHAR column is byte-based, not character-based.

## What is data type in database?

A database data type refers **to the format of data storage that can hold a distinct type or range of values**. When computer programs store data in variables, each variable must be designated a distinct data type. Some common data types are as follows: integers, characters, strings, floating point numbers and arrays.

## What is difference between Bigint and int?

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). Let us see an example.

## What is data type in SQL?

A data type is **an attribute that specifies the type of data that the object can hold**: integer data, character data, monetary data, date and time data, binary strings, and so on. SQL Server supplies a set of system data types that define all the types of data that can be used with SQL Server.

## 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.

## What are the four integer data types?

**The standard Java integer data types are:**

- byte 1 byte -128 to 127.
- short 2 bytes -32,768 to 32,767.
- int 4 bytes -2,147,483,648 to 2,147,483,647.
- long 8 bytes -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.

## What is integer data type with example?

An integer is **a whole number (not a fraction) that can be positive, negative, or zero**. Therefore, the numbers 10, 0, -25, and 5,148 are all integers. … For example, 6 divided by 3 equals 2, which is an integer, but 6 divided by 4 equals 1.5, which contains a fraction.

## What are the two types of data types?

There are two general types of data – **quantitative and qualitative** and both are equally important.

## What is BIGINT data type?

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. … The range of big integers is -9223372036854775808 to 9223372036854775807.

## What is data type varchar?

The VARCHAR data type is **the IBM® Informix® implementation of a character varying data type**. … The ANSI standard data type for varying-length character strings is CHARACTER VARYING. The size of the maximum size (m) parameter of a VARCHAR column can range from 1 to 255 bytes.

## What is data type for date in SQL?

Date and Time data types

Data type | Format | Accuracy |
---|---|---|

date | YYYY-MM-DD |
1 day |

smalldatetime | YYYY-MM-DD hh:mm:ss | 1 minute |

datetime | YYYY-MM-DD hh:mm:ss[.nnn] | 0.00333 second |

datetime2 | YYYY-MM-DD hh:mm:ss[.nnnnnnn] | 100 nanoseconds |
