CREATE SCHEMA creates a new schema in the current database.
A schema is essentially a namespace: it contains named objects (tables, data types, functions, and operators) whose names can duplicate those of other objects existing in other schemas.
Named objects in a schema can be accessed by using the schema name as prefix or by setting the schema name in the search path.
create_schema_name ::= CREATE SCHEMA [ IF NOT EXISTS ] schema_name [ AUTHORIZATION role_specification ] [ schema_element [ ... ] ] create_schema_role ::= CREATE SCHEMA [ IF NOT EXISTS ] AUTHORIZATION role_specification [ schema_element [ ... ] ] schema_element ::= '<YSQL DDL statement>' role_specification ::= role_name | CURRENT_USER | SESSION_USER
schema_nameis the name of the schema being created. If no schema_name is specified, the
role_nameis the role who will own the new schema. If omitted, it defaults to the user executing the command. To create a schema owned by another role, you must be a direct or indirect member of that role, or be a superuser.
schema_elementis a YSQL statement defining an object to be created within the schema. Currently, only
GRANTare supported as clauses within
CREATE SCHEMA. Other kinds of objects may be created in separate commands after the schema is created.
Create a new schema.
yugabyte=# CREATE SCHEMA IF NOT EXIST branch;
Create a schema for a user.
yugabyte=# CREATE ROLE John; yugabyte=# CREATE SCHEMA AUTHORIZATION john;
Create a schema that will be owned by another role.
yugabyte=# CREATE SCHEMA branch AUTHORIZATION john;
Create a schema and an object within that schema.
yugabyte=# CREATE SCHEMA branch CREATE TABLE dept( dept_id INT NOT NULL, dept_name TEXT NOT NULL, PRIMARY KEY (dept_id) );
