DROP SCHEMA

DROP SCHEMA can be used to remove a schema.

The schema has to be empty before removal.

SQream DB does not support dropping a schema with objects.

See also: CREATE SCHEMA, ALTER DEFAULT SCHEMA, and RENAME SCHEMA.

Permissions

The role must have the DDL permission at the database level.

Syntax

drop_schema_statement ::=
    DROP SCHEMA schema_name
    ;

schema_name ::= identifier

Parameters

Parameter	Description
schema_name	The name of the schema to drop

Examples

Dropping a schema

DROP SCHEMA test;

Dropping a schema if it’s not empty

If a schema contains several tables, SQream DB will alert you that these tables need to be dropped first.

This prevents accidental dropping of full schemas.

t=> DROP SCHEMA test;
Schema 'test' contains the following objects:
Tables - 'test.foo' , 'test.bar'
Please drop its content and then try again.

To drop the schema, drop the schema’s tables first, and then drop the schema:

t=> DROP TABLE test.foo;
executed
t=> DROP TABLE test.bar;
executed
t=> DROP SCHEMA test;
executed
