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
