Access Control Privileges¶

This topic describes the privileges that are available in the Snowflake access control model. Privileges are granted to roles, and roles are granted to users, to specify the operations that the users can perform on objects in the system.

In this Topic:

Pipe Privileges
Stream Privileges
Task Privileges
Other Database Object Privileges (Sequences, UDFs)

All Privileges (Alphabetical)¶

The following privileges are available in the Snowflake access control model. The meaning of each privilege varies depending on the object type to which it is applied, and not all objects support all privileges:

Privilege	Object Type	Description
ALL [ PRIVILEGES ]	All	Grants all the privileges for the specified object type.
CREATE <object_type>	Global , Database , Schema	Grants ability to create an object of <object_type> (e.g. CREATE TABLE grants the ability to create a table within a schema).
CREATE ACCOUNT	Global	Grants ability to create managed accounts; currently applies only to data providers creating reader accounts for sharing data with consumers.
CREATE SHARE	Global	Grants ability to create shares; applies to data providers for sharing data with other accounts.
DELETE	Table	Grants ability to execute a DELETE command on the table.
IMPORT SHARE	Global	Grants ability to view shares shared with your account and create databases from the shares; applies to data consumers.
IMPORTED PRIVILEGES	Table	Grants ability to enable roles other than the owning role to access a shared database; applies only to shared databases.
INSERT	Table	Grants ability to execute an INSERT command on the table.
MANAGE GRANTS	Global	Grants ability to grant or revoke privileges on any object as if the invoking role were the owner of the object.
MODIFY	Resource Monitor , Warehouse , Database , Schema	Grants ability to change the settings or properties of an object (e.g. on a virtual warehouse, provides the ability to change the size of a virtual warehouse).
MONITOR	Resource Monitor , Warehouse , Database , Schema	Grants ability to see details within an object (e.g. queries and usage within a warehouse).
MONITOR USAGE	Global	Grants ability to monitor account-level usage and historical information for databases and warehouses; for more details, see Enabling Non-Account Administrators to Monitor Usage and Billing History. Additionally grants ability to view managed accounts using SHOW MANAGED ACCOUNTS.
OPERATE	Warehouse	Grants ability to start, stop, suspend, or resume a virtual warehouse.
OWNERSHIP	All	Grants ability to delete, alter, and grant or revoke access to an object. Required to rename an object. OWNERSHIP is a special privilege on an object that is automatically granted to the role that created the object, but can also be transferred using the GRANT OWNERSHIP command to a different role by the owning role (or any role with the MANAGE GRANTS privilege).
REFERENCES	Table	Grants ability to reference a table as the unique/primary key table for a foreign key constraint.
SELECT	Table , External table, View, Stream	Grants ability to execute a SELECT statement on the table/view.
TRUNCATE	Table	Grants ability to execute a TRUNCATE TABLE command on the table.
UPDATE	Table	Grants ability to execute an UPDATE command on the table.
USAGE	Warehouse , Database , Schema	Grants ability to execute a USE <object> command on the object; also grants ability to execute a SHOW <objects> command on the objects within a database or schema; however, a contained object is only listed in the output if the executing role also has at least one privilege on the object.

The remaining sections in this topic describe the specific privileges available for each type of object and their usage.

Integration Privileges¶

Note

Storage integrations only; other integration types (notification, security) have no object-level privileges.

Database Privileges¶

Privilege	Usage
MODIFY	Enables altering any settings of a database.

Note that changing the properties of a database, including comments, requires the OWNERSHIP privilege for the database.

Schema Privileges¶

Privilege	Usage
MODIFY	Enables altering any settings of a schema.
MONITOR	Enables viewing details for a schema.
USAGE	Enables using a schema, including executing SHOW SCHEMAS commands to list the schema details in a database.
	To execute SHOW <objects> commands for objects (tables, views, stages, file formats, sequences, pipes, or functions) in the schema, a role must have at least one privilege granted on the object.

Changing the properties of a schema, including comments, requires the OWNERSHIP privilege for the database.
Operating on a schema also requires the USAGE privilege on the parent database.

Table Privileges¶

Privilege	Usage
SELECT	Enables executing a SELECT statement on a table.
INSERT	Enables executing an INSERT command on a table. Also enables using the ALTER TABLE command with a `RECLUSTER` clause to manually recluster a table with a clustering key.

ALL [ PRIVILEGES ]	Grants all privileges, except OWNERSHIP, on a table.
OWNERSHIP	Transfers ownership of a table, which grants full control over the table. Required to alter most properties a table, with the exception of reclustering.

Note

Operating on a table also requires the USAGE privilege on the parent database and schema.

External Table Privileges¶

Privilege	Usage
SELECT	Enables executing a SELECT statement on an external table.
ALL [ PRIVILEGES ]	Grants all privileges, except OWNERSHIP, on an external table.
OWNERSHIP	Transfers ownership of a view, which grants full control over the external table; required to refresh an external table.

Privilege	Usage
SELECT	Enables executing a SELECT statement on a view.
ALL [ PRIVILEGES ]	Grants all privileges, except OWNERSHIP, on a view.
OWNERSHIP	Transfers ownership of a view, which grants full control over the view. Required to alter a view.

Note

A user who has SELECT privilege on a view does not also need SELECT privilege on the tables that the view uses. This means that you can use a view to give a role access to only a subset of a table. For example, you can create a view that accesses medical billing information but not medical diagnosis information in the same table, and you can then grant privileges on that view to the “accountant” role so that the accountants can look at the billing information without seeing the patient’s diagnosis.

Operating on a view also requires the USAGE privilege on the parent database and schema.

Stage Privileges¶

Privilege	Usage
USAGE	Enables using an external stage object in a SQL statement; not applicable to internal stages.
READ	Enables performing any operations that require reading from an internal stage (GET, LIST, COPY INTO <table>, etc.); not applicable to external stages.
WRITE	Enables performing any operations that require writing to an internal stage (PUT, REMOVE, COPY INTO <location>, etc.); not applicable for external stages.
ALL [ PRIVILEGES ]	Grants all applicable privileges, except OWNERSHIP, on the stage (internal or external).
OWNERSHIP	Transfers ownership of a stage, which grants full control over the stage.

Note

When granting both the READ and WRITE privileges for an internal stage, the READ privilege must be granted before or at the same time as the WRITE privilege.
When revoking both the READ and WRITE privileges for an internal stage, the WRITE privilege must be revoked before or at the same time as the READ privilege.
Operating on a stage also requires the USAGE privilege on the parent database and schema.

File Format Privileges¶

Privilege	Usage
USAGE	Enables utilizing a file format in a SQL statement.
ALL [ PRIVILEGES ]	Grants all privileges, except OWNERSHIP, on the file format.
OWNERSHIP	Transfers ownership of a file format, which grants full control over the file format. Required to alter a file format.

Note

Operating on file formats also requires the USAGE privilege on the parent database and schema.
