DROP SCHEMA¶
Function¶
DROP SCHEMA deletes a schema in a database.
Precautions¶
Only a schema owner or a system administrator can run the DROP SCHEMA command.
Syntax¶
DROP SCHEMA [ IF EXISTS ] schema_name [, ...] [ CASCADE | RESTRICT ];
Parameter Description¶
IF EXISTS
Sends a notice instead of an error if the specified schema does not exist.
schema_name
Specifies the name of a schema.
Value range: An existing schema name.
CASCADE | RESTRICT
CASCADE: automatically deletes all objects that are contained in the schema to be deleted.
RESTRICT: refuses to delete the schema that contains any objects. This is the default.
Important
Do not delete the schemas with the beginning of pg_temp or pg_toast_temp. They are internal system schemas, and deleting them may cause unexpected errors.
Note
A user cannot delete the schema in use. To delete the schema in use, switch to another schema.
Example¶
Delete the ds_new schema.
DROP SCHEMA ds_new;
