# SHOW FUNCTIONS

Lists any existing user-defined functions in the specified database, including user-defined scalar-valued functions (UDFs) and user-defined table-valued functions (TVFs).

## Syntax

```sql
SHOW FUNCTIONS [{FROM | IN} database_name] [LIKE pattern]

```

## Remarks

* The `SHOW FUNCTIONS` command can be used to list functions in the current database or in another database. The function list returns the name for each function and who is the function definer. To show user-defined aggregate functions (UDAFs), see [SHOW AGGREGATES](https://docs.singlestore.com/cloud/reference/sql-reference/procedural-sql-reference/show-aggregates.md). Use [SHOW PROCEDURES](https://docs.singlestore.com/cloud/reference/sql-reference/procedural-sql-reference/show-procedures.md) to list stored procedures.
* The Data Format column can be one of: JSON or ROWDAT\_1.
* The Link column shows the Connection Link.

## Example - List Functions

The following example lists each function in the current database.

```sql
SHOW FUNCTIONS;

```

```output
