sql server - using "USE" keyword Vs. full table name in T-SQL -


When I want to select the table wi in table wi 

  from select * X]. [DBO]. [Y]

or 

  selection of USE X * from [Y]

debo
Use the debob as the owner of all database objects to manage objects Can make it easy. Your database will always be a DBO user in the database, as long as the user has the proper permissions, he will be able to access any object owned by the debob without specifying the owner.

USE X
When a SQL Server login connects to SQL Server, the login is automatically linked to its default database and receives the database user's security context is. If a database user is created for SQL Server login, the login joins as a guest if the database user does not have permission to connect to the database, the USE statement will fail. If no default database is specified for login, its default database will be set to master.
