ROUTINES view
The INFORMATION_SCHEMA.ROUTINES view contains one row for each routine in a
dataset.
Required permissions
To query the INFORMATION_SCHEMA.ROUTINES view, you need the following
Identity and Access Management (IAM) permissions:
- bigquery.routines.get
- bigquery.routines.list
Each of the following predefined IAM roles includes the permissions that you need in order to get routine metadata:
- roles/bigquery.admin
- roles/bigquery.metadataViewer
- roles/bigquery.dataViewer
For more information about BigQuery permissions, see Access control with IAM.
Schema
When you query the INFORMATION_SCHEMA.ROUTINES view, the query results contain
one row for each routine in a dataset.
The INFORMATION_SCHEMA.ROUTINES view has the following schema:
| Column name | Data type | Value | 
|---|---|---|
| SPECIFIC_CATALOG | STRING | The name of the project that contains the dataset where the routine is defined | 
| SPECIFIC_SCHEMA | STRING | The name of the dataset that contains the routine | 
| SPECIFIC_NAME | STRING | The name of the routine | 
| ROUTINE_CATALOG | STRING | The name of the project that contains the dataset where the routine is defined | 
| ROUTINE_SCHEMA | STRING | The name of the dataset that contains the routine | 
| ROUTINE_NAME | STRING | The name of the routine | 
| ROUTINE_TYPE | STRING | The routine type: 
 | 
| DATA_TYPE | STRING | The data type that the routine returns. NULLif the
      routine is a stored procedure | 
| ROUTINE_BODY | STRING | How the body of the routine is defined, either SQLorEXTERNALif the routine is a JavaScript user-defined
      function | 
| ROUTINE_DEFINITION | STRING | The definition of the routine | 
| EXTERNAL_LANGUAGE | STRING | JAVASCRIPTif the routine is a JavaScript
        user-defined function orNULLif the routine was defined
        with SQL | 
| IS_DETERMINISTIC | STRING | YESif the routine is known to be deterministic,NOif it is not, orNULLif unknown | 
| SECURITY_TYPE | STRING | Security type of the routine, always NULL | 
| CREATED | TIMESTAMP | The routine's creation time | 
| LAST_ALTERED | TIMESTAMP | The routine's last modification time | 
| DDL | STRING | The DDL statement
        that can be used to create the routine, such as CREATE FUNCTIONorCREATE PROCEDURE | 
| CONNECTION | STRING | The connection name, if the routine has one. Otherwise NULL | 
Scope and syntax
Queries against this view must include a dataset or a region qualifier. For more information see Syntax. The following table explains the region and resource scopes for this view:
| View name | Resource scope | Region scope | 
|---|---|---|
| [PROJECT_ID.]`region-REGION`.INFORMATION_SCHEMA.ROUTINES | Project level | REGION | 
| [PROJECT_ID.]DATASET_ID.INFORMATION_SCHEMA.ROUTINES | Dataset level | Dataset location | 
- 
  Optional: PROJECT_ID: the ID of your Google Cloud project. If not specified, the default project is used.
- 
  REGION: any dataset region name. For example,`region-us`.
- 
  DATASET_ID: the ID of your dataset. For more information, see Dataset qualifier.
Example
-- Returns metadata for routines in a single dataset.
SELECT * FROM myDataset.INFORMATION_SCHEMA.ROUTINES;
-- Returns metadata for routines in a region.
SELECT * FROM region-us.INFORMATION_SCHEMA.ROUTINES;
Example
Example
To run the query against a project other than your default project, add the project ID to the dataset in the following format:
`PROJECT_ID`.INFORMATION_SCHEMA.ROUTINES
`myproject`.INFORMATION_SCHEMA.ROUTINES.
The following example retrieves all columns from the
INFORMATION_SCHEMA.ROUTINES view. The metadata returned is for all routines in
mydataset in your default project — myproject. The dataset mydataset
contains a routine named myroutine1.
SELECT * FROM mydataset.INFORMATION_SCHEMA.ROUTINES;
The result is similar to the following:
