# Functions overloading

Snowflake support [procedures and functions overloading](https://docs.snowflake.com/en/developer-guide/udf-stored-procedure-naming-conventions#overloading-procedures-and-functions). You can create multiple UDFs with the same name but with different types of arguments..

Let's create:

```sql
CREATE TABLE A(ID INT);
CREATE TABLE B(S STRING);

CREATE OR REPLACE FUNCTION fn_overload ( _id number )
  RETURNS TABLE (id int)
  AS 'select id from a where id > _id'
;


CREATE OR REPLACE FUNCTION fn_overload ( _s string )
  RETURNS TABLE (s string)
  AS 'select s from b where s != _s'
;
```

The first one has **Table A as a source**, and the second one **Table B**.

Now let's create VIEWs depending on these functions:

```sql
CREATE VIEW V1 AS
SELECT * FROM TABLE(fn_overload(1));

CREATE VIEW V2 AS
SELECT * FROM TABLE(fn_overload('1'));
```

Here is the [**Dwh.dev**](https://dwh.dev/) result:

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dwh.dev/snowflake-sql-syntax-and-behavior/functions-overloading.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
