**Is There INTEGER Data Type in Oracle?**

In Oracle, there is no specific __INTEGER data type__ like in some other programming languages. However, Oracle provides several numeric data types that can be used to store whole numbers with different ranges and precision levels.

## Numeric Data Types in Oracle

Oracle offers various numeric data types to accommodate different requirements for storing whole numbers. Some of the commonly used numeric data types are:

**NUMBER:**This is the most commonly used numeric data type in Oracle. It can store positive and negative numbers with decimal precision.**INTEGER:**Although there is no dedicated INTEGER data type, you can use the NUMBER data type with a precision of zero to achieve similar functionality.**SMALLINT:**This is a smaller version of the NUMBER data type and can store smaller whole numbers with a range of -32,768 to 32,767.**BINARY_INTEGER:**This is a subtype of the PL/SQL INTEGER data type and is primarily used in PL/SQL code.

## Using NUMBER Data Type as an INTEGER Equivalent

To simulate an INTEGER data type in Oracle, you can use the NUMBER data type with a precision of zero. This allows you to store whole numbers without any decimal places. For example:

```
CREATE TABLE my_table (
id NUMBER(10,0),
name VARCHAR2(50)
);
```

In this example, the column “id” is defined as a NUMBER with a precision of zero (i.e., no decimal places). It can be used to store integer values.

## Benefits of Using NUMBER Data Type

Although Oracle doesn’t have a dedicated INTEGER data type, using the NUMBER data type with a precision of zero offers several advantages:

**Flexibility:**By using the NUMBER data type, you can store both whole numbers and decimal numbers in the same column if needed.**Wide Range:**The NUMBER data type provides a wide range of values that can be stored, allowing you to handle large integers as well.**Compatibility:**As the NUMBER data type is widely supported in Oracle, it ensures compatibility across different systems and applications.

### Conclusion

In conclusion, while there is no specific INTEGER data type in Oracle, you can use the NUMBER data type with a precision of zero to store whole numbers effectively. This approach offers flexibility, a wide range of values, and compatibility with other systems. So even though there isn’t an INTEGER data type per se, Oracle provides alternatives that fulfill similar requirements.
