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.
