The SELECT statement is the primary means of extracting data from database tables, and allows you to determine exactly which data you want to extract by means of different comparison operators used in the WHERE clause. This includes the use of specific "wild card" characters which allow you to search for character or number patterns within the data. You can also perform mathematical expressions within the SELECT statement to create derived output. The ORDER BY clause allows you to sort the output data in either ascending (the default) or descending order. Lab #5 will explore all of these applications of the SELECT statement.…

To this day, there is still a fine sharp line drawn in the very dirt of the big, wide, expanse of the work field. You are either in management or, the common laborer who resides below the manager, working long shifts with little pay. Employers think managers, as representatives of business owners, should have all the power. They should be able to hire and fire workers at will, for any reason or no reason. They should pay only the wages dictated by supply and demand. They should set the hours, pace and conditions of work for maximum productivity. Laborers on the other hand believe that work isn’t something to be purchased or sold off like cattle; they believe that their wages should be enough to allow them to be able to comfortably support themselves, regardless of the current economic conditions or production rates. There is certainly no doubt that if asked, anyone would choose to be on the management side of the work field. But without laborers, there would be no production, and no production is no business. So that’s why I choose to focus on the laborers of the work field and find a happy medium between laborers and management.…
