Function

Adds a new publication to the current database. The publication name must be different from the name of any existing publication in the current database. A publication is essentially the replication of data changes in a set of tables achieved by logical replication.

Precautions

This statement is supported by clusters of version 8.2.0.100 or later.
If neither FOR TABLE nor FOR ALL TABLES is specified, a publication starts with a set of empty tables. Tables can be added later.
Creating a publication does not start replication. It defines only one group and filtering logic for future subscribers. To create a publication, the caller must have CREATE permission on the current database.
To add a table to a publication, the caller must have ownership of the table. To use FOR ALL TABLES and FOR ALL TABLES IN SCHEMA clauses, the caller must have system administrator permissions.
Do not add a table to the same publication by using FOR TABLE and FOR ALL TABLES IN SCHEMA.

Syntax

CREATE PUBLICATION name
    [ FOR ALL TABLES
      | FOR publication_object [, ... ] ]
    [ WITH ( publication_parameter [=value] [, ... ] ) ];

The syntax of using publication_object is as follows:

TABLE table_name [, ...]
| ALL TABLES IN SCHEMA schema_name [, ... ]

Parameter Description

name
Specifies the name of a new publication.

Value range: A string. It must comply with the naming convention.
FOR ALL TABLES
Marks a publication as replications of all fines-grained DR primary table changes in the database, including tables to be created.
FOR TABLE
Specifies the list of tables to be added to a publication. Only the fine-grained DR primary table can be a part of the publication.
table_name
Name of the table to be added to the publication, which can include the schema name.

Value range: A string. It must comply with the naming convention.
FOR ALL TABLES IN SCHEMA
Marks a publication as replications of all fines-grained DR primary table changes a specified schema list, including tables to be created.
schema_name
The name of the schema to be added to the publication.

Value range: A string. It must comply with the naming convention.
WITH ( publication_parameter [=value] [, ... ] )
Specifies optional parameters for a publication. The following parameters are available:
- publish
  Specifies the DML operations that will be published to the subscriber.
  
  Value range: A string. Separate the operations by commas (,). The available operations are insert, update, delete, and truncate.
  
  By default, all actions are released. Therefore, the default value of this option is insert, update, delete, and truncate.

Examples

Create a publication for all changes of two tables and two schemas.

Create sample table tpcds.ship_mode_t1.

CREATE TABLE tpcds.ship_mode_t1
(
    SM_SHIP_MODE_SK           INTEGER               NOT NULL,
    SM_SHIP_MODE_ID           CHAR(16)              NOT NULL,
    SM_TYPE                   CHAR(30)                      ,
    SM_CODE                   CHAR(10)                      ,
    SM_CARRIER                CHAR(20)                      ,
    SM_CONTRACT               CHAR(20)
) WITH (ORIENTATION = COLUMN,enable_disaster_cstore='on')
DISTRIBUTE BY HASH(SM_SHIP_MODE_SK);

Create sample table tpcds.customer_address_p1.

CREATE TABLE tpcds.customer_address_p1
(
    CA_ADDRESS_SK             INTEGER               NOT NULL,
    CA_ADDRESS_ID             CHAR(16)              NOT NULL,
    CA_STREET_NUMBER          CHAR(10)                      ,
    CA_STREET_NAME            VARCHAR(60)                   ,
    CA_STREET_TYPE            CHAR(15)                      ,
    CA_SUITE_NUMBER           CHAR(10)                      ,
    CA_CITY                   VARCHAR(60)                   ,
    CA_COUNTY                 VARCHAR(30)                   ,
    CA_STATE                  CHAR(2)                       ,
    CA_ZIP                    CHAR(10)                      ,
    CA_COUNTRY                VARCHAR(20)                   ,
    CA_GMT_OFFSET             DECIMAL(5,2)                  ,
    CA_LOCATION_TYPE          CHAR(20)
) WITH (ORIENTATION = COLUMN,enable_disaster_cstore='on')
DISTRIBUTE BY HASH(CA_ADDRESS_SK);

Create sample schema myschema1.

CREATE SCHEMA myschema1;

Create sample schema myschema2.

CREATE SCHEMA myschema2;

Create a publication for all changes of two tables and two schemas.

CREATE PUBLICATION mypublication FOR TABLE users, departments, ALL TABLES IN SCHEMA myschema1, myschema2;

Create a publication for all changes in all tables.
```
CREATE PUBLICATION alltables FOR ALL TABLES;
```
