CIS-336 : Lab7 : Working with Views LAB OVERVIEW
Lab 7 will introduce the concept of database views . This lab may be completed using either DeVry ‘ sOmnymbus EDUPE-APP lab environment , or a local copy of the MySQL database running on your own computer using the OM database tables . The lab will utilize a set of tables that are represented by the ERD ( OM _ ERD . docx ) and are created and populated by the script file ( create _ OM _ db . sql ). Follow the instructions in the file CreateOMTables . docx to create your database , tables , and data .
A few IMPORTANT things to note if using EDUPE MySQL : ** There can be NO SPACES in alias names given to a column . For example : Select unit _ price as ― Retail Price ― from items ; – this does NOT work in EDUPE MySQL . Any of the following WILL WORK : Select unit _ price as ― RetailPrice ‖ from items ; Select unit _ price as ― Retail _ Price ‖ from items ; Select unit _ price as Retail _ Price from items ; Select unit _ price as RetailPrice from items ;
** Any calculated fields MUST be given an alias ( and note above NO SPACES in alias ). For example :
select unit _ price * 2 from items ; – this does NOT work in EDUPE MySQL This will work : select unit _ price * 2 as NewPrice from items ; Deliverables
