Therefore, if you select records directly without specifying the schema, it looks for an object in the default DBO schema. For example, as shown above, we have in all schemas. You are required to specify the table schema in order to fetch data from the correct schema. Note: You can create a table with a similar name in the different schema of a database. For example, the below script creates a TableA in the dbo schema. If you do not specify a schema while creating the object, SQL Server uses the default schema. For example, the below query returns with its schema. You can join sys.tables and sys.schema system tables to list the table name with their schemas. For example, the following script creates in different schemas, and. To create objects such as a table, we need to specify the schema name in which the object will be created. You can refresh the database and view the newly created schema as shown below. The script to create schemas, and with schema owner is shown below. Authorization: This is the schema owner name.Schema_name: This is the schema that we want to create.To create a new SQL Server schema, we use the CREATE SCHEMA t-SQL statement. ORDER BY s.name Creating a SQL Server schema using CREATE SCHEMA INNER JOIN sys.sysusers u ON u.uid = s.principal_id To do this in SSMS, you would connect to the SQL instance, expand the SQL database and view the schemas under the security folder.Īlternatively, you could use the sys.schemas to get a list of database schemas and their respective owners. You can get a list of the schemas using an SSMS or T-SQL query. Listing all database schemas in the current database We can query SCHEMA_NAME() to get the default schema for the connected user. You can have the same schema in different databases of a SQL Server instance.īy default, SQL Server uses schema for all objects in a database. Note: The schema is a database-scoped entity. Each schema (logical group) contains SQL Server objects such as tables, stored procedures, views, functions, indexes, types and synonyms. Similarly, finance department tables should be in the schema. For example, the tables and stored procedures for the HR department should be logically grouped in the schema. Suppose for your organization’s database, you want to group objects based on departments.
