We can use one line DROP SCHEMA statement for deleting multiple schemas as follows:ĭROP SCHEMA schema_name_1 Note: You need to be a superuser or the schema owner to execute the DROP SCHEMA statement. IIf you want to remove empty schema only, then add the RESTRICT keyword.Use CASCADE to remove a schema, and all of its objects and all other objects are also deleted, which depends on those objects.Specify the IF EXISTS keywords which is optional to remove a schema only if the specified schema exists in the current database.Define the schema name after DROP SCHEMA, which we want to delete.The DROP SCHEMA is used to remove a schema from the current database and remove all of its objects.ĭROP SCHEMA schema_name Output: As a result of the above statement, we will get the following statistics: It also creates a table named ‘Transactions’ and a view named Transactions_list that belongs to the EduCBASCM schema: The following example uses the CREATE SCHEMA statement to create a new schema named EduCBASCM. Create a schema for EduCBA user:Ĭreate a schema and its objects in a single statement. Output: The following result will be shown after executing the above statement:Ĭreate a new schema for a specific user. We can fetch all schemas from the current database using the following statements. Create a new schema named EduCBASchema:ĬREATE SCHEMA IF NOT EXISTS EduCBASchema You can create a schema and list of data objects in a single statement.Ĭreate a New Schema. This is similar to Syntax 1 only difference because for creating a schema for the specific users, we need to specify the user_name after the AUTHORIZATION keyword, which is the same as the schema name. We can create a schema for a specific user as well:ĬREATE SCHEMA AUTHORIZATION user_name If you try to create a new schema that already exists in the current database without using the IF NOT EXISTS clause will result in an error. IF NOT EXISTS is an option clause that adds a condition for creating the new schema only if it does not exist. The name of the schema should be unique within the current database.
