ALTER DATASHARE

Changes the definition of a datashare. You can add objects or remove objects using ALTER DATASHARE.

Syntax

ALTER DATASHARE datashare_name { ADD | REMOVE } { 
TABLE schema.table [, ...] 
| SCHEMA schema [, ...] 
| FUNCTION schema.sql_udf [, ...] 
| ALL TABLES IN SCHEMA schema [, ...]  
| ALL FUNCTIONS IN SCHEMA schema [, ...] }
[ SET PUBLICACCESSIBLE [=] TRUE | FALSE ] 

Parameters

datashare_name

The name of the datashare to be altered.

ADD | REMOVE

A clause that specifies whether to add objects to or remove objects from the datashare.

TABLE schema.table [, ...]

The name of the table or view in the specified schema to add to the datashare.

SCHEMA schema [, ...]

The name of the schema to add to the datashare.

FUNCTION schema.sql_udf [, ...]

The name of the user-defined SQL function to add to the datashare.

ALL TABLES IN SCHEMA schema [, ...]

A clause that specifies adding all tables in the specified schema to the datashare.

ALL FUNCTIONS IN SCHEMA schema [, ...] }

A clause that specifies adding all functions in the specified schema to the datashare.

[ SET PUBLICACCESSIBLE [=] TRUE | FALSE ]

A clause that specifies whether a datashare can be shared to clusters that are publicly accessible.

The default value for SET PUBLICACCESSIBLE is TRUE.

Usage notes

The following users can alter a datashare:

• A superuser

• The owner of the datashare

• Users who have SELECT, USAGE, or ALL privileges on the objects in the datashare

You can share tables, regular views, late-binding views, materialized views, SQL user-defined functions (UDFs), and entire schemas. When you add a schema, Amazon Redshift doesn't add all the objects under it. You must add them explicitly.

Examples

The following example adds the public.tickit_venue_redshift table to the datashare SalesShare.

ALTER DATASHARE SalesShare ADD TABLE public.tickit_sales_redshift;

The following example adds all tables to the datashare SalesShare.

ALTER DATASHARE SalesShare ADD ALL TABLES IN SCHEMA PUBLIC;

The following example removes the public.tickit_venue_redshift table from the datashare SalesShare.
