If you want to delete the schema STUDENT_DETAILS, then use the following SQL query. The DROP SCHEMA in SQL is used to delete all tables present in that particular schema. The following query will result in the desired result.ĪLTER SCHEMA STUDENT How to Drop a Schema? Suppose we want to rename the previously created schema- STUDENT as STUDENT_DETAILS and pass the ownership to new user DAVID. Here, new_schema_name refers to the name to which you want to rename the existing schema and new_user_name refers to the new owner of the schema. Syntax for Altering a Schema:ĪLTER SCHEMA schema_name ![]() The ALTER SCHEMA statement is used to rename a schema or specify a new owner, who must be a pre-existing database user. Further, the CREATE command will create the table named DETAILS under the STUDENT schema. The above query will create a schema named as STUDENT and with user STUDENT as the owner of the schema. It contains one or more GRANT statements.ĬREATE SCHEMA STUDENT AUTHORIZATION STUDENT It contains one or more CREATE statements Specifies the path and name of a file (optional). It is used to specify the default character set that is used by all objects in that schema. It is used to identify the user of the mentioned schema. This describes the schema name that we want to create. You can create a schema in SQL by following the below syntax. When objects have circular references, such as when we need to construct two tables, one with a foreign key referencing the other table, creating schemas can be useful. If you prefer to exclude schemas from the database, they will never appear on a new database. Objects in the schemas mentioned above cannot be dropped or removed. Here are a few examples of built-in schema: It persists primarily for backward compatibility. SQL Server comes with a certain predefined schema that shares the same names as the built-in database functions and users. Since a schema allows for the logical aggregation of database objects, it can assist us in cases where the database object name is the same but falls into a separate logical category.This is advantageous when several people are collaborating on the same database program and the architecture team needs to keep the database tables' credibility. Database objects can be grouped into logical groups using schemas.A user can be removed without removing the database items that are connected with the user.We gain greater power over the access and protection of database objects.It enables you to transfer database objects between schemas.A schema may be shared by several users.A SQL schema can be easily transferred to another user.Advantages of Using Schemaįollowing are some of the main advantages of using a schema in SQL: It increases the database's stability for security-related management. Schemas may be assigned security permissions, making them an effective method for distinguishing and defending database objects based on user access privileges. In other words, schemas are similar to separate namespaces or containers used to handle database files. As of SQL Server 2005, a schema is an individual entity (container of objects) distinct from the user who constructs the object. A database user owns the schema, which has the same name as the database manager. In a SQL database, a schema is a list of logical structures of data.
