Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/) that was published on June 30, 2025. 

# IS\_INTEGER function

The IS\_INTEGER function is a superset of the IS\_SMALLINT function.

## Syntax

<a name="r_is_integer_example"></a>

To check if `5` is an `INTEGER` using the IS\_INTEGER function, use the following example.

```
CREATE TABLE t(s SUPER);

INSERT INTO t VALUES (5);

SELECT s, IS_INTEGER(s) FROM t;

+---+------------+
| s | is_integer |
+---+------------+
| 5 | true       |
+---+------------+
```
