Create Database (cont'd) The WPC database object is displayed in the Summary window showing the folder structure that will contain the database objects The WPC database object in the Object Explorer expanded to show the folder structure that will be used to contain the database objects

Scripts This is the Microsoft Notepad text editor—the file name is DBC-e03- MSSQL-WPC-Create-Tables.sql The SQL keyword Name is enclosed in brackets as [Name] The lines that start with /* are comments—any text between the /* and the */ characters on a line is a comment and ignored by the DBMS when it runs the SQL
