Can we use number datatype in MySQL?
MySQL supports all standard SQL numeric data types. These types include the exact numeric data types ( INTEGER , SMALLINT , DECIMAL , and NUMERIC ), as well as the approximate numeric data types ( FLOAT , REAL , and DOUBLE PRECISION ).
What is Number data type in Oracle?
The Oracle NUMBER data type is used to store numeric values that can be negative or positive. The following illustrates the syntax of the NUMBER data type: NUMBER[(precision [, scale])] The Oracle NUMBER data type has precision and scale. The precision is the number of digits in a number.

Numeric Datatypes
| Data Type Syntax | Maximum Size |
|---|---|
| BIGINT(m) | Big integer value. Signed values range from -9223372036854775808 to 9223372036854775807. Unsigned values range from 0 to 18446744073709551615. |
| DECIMAL(m,d) | Unpacked fixed point number. m defaults to 10, if not specified. d defaults to 0, if not specified. |
What is number type in SQL?
In SQL, numbers are defined as either exact or approximate. The exact numeric data types are SMALLINT , INTEGER , BIGINT , NUMERIC(p,s) , and DECIMAL(p,s) . The approximate numeric data types are FLOAT(p) , REAL , and DOUBLE PRECISION .
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 is means by INT 11 in MySQL?
in int(11), 11 is the display width of the integer column, unlike the characters columns where the number means number of character that can be stored. int(11) – The number in the parenthesis i.e () does not determines the max and min values that can be stored in the integer field.
Which is a numbering data type?
Numeric data types are numbers stored in database columns. These data types are typically grouped by: The exact numeric types are INTEGER , BIGINT , DECIMAL , NUMERIC , NUMBER , and MONEY . Approximate numeric types, values where the precision needs to be preserved and the scale can be floating.

Table 3-1 Internal Oracle Datatypes
| Internal Oracle Datatype | Maximum Internal Length | Datatype Code |
|---|---|---|
| NUMBER | 21 bytes | 2 |
| LONG | 2^31-1 bytes (2 gigabytes) | 8 |
| ROWID | 10 bytes | 11 |

What is difference between BIGINT and int?
The int type takes 4 byte signed integer i.e. 32 bits ( 232 values can be stored). The BigInt type takes 8 byte signed integer i.e. 64 bits (264 values can be stored). Let us see an example.
What does int 5 mean in MySQL?
In MySQL, INT(5) does not mean that values are limited to 5-character values. It only means that MySQL will try to pad these values with spaces/zeroes when returning them. The numeric range of any signed INT including INT(10), INT(5) or any other INT(n) is: -2,147,483,648 2,147,483,647, which is 10 digits at most.
