Micr osof t Access 20 13 does not suppor t all SQ L -92 ( and newer) const r ucts.

W hile t his c hapt er st ill consider s Micr osof t Access as t he DBMS m ost lik ely t o be used by st udent s at t his point in t he cour se, t her e are some Revie w Q uestions and Proj ect Q uestions t hat use t he O RDER BY clause wit h aliased com put ed columns t hat wil l not r un in Access ( see Review Q uest ions 2. 42 – 2.44 and Pr oj ect Q uest ions 2. 63. e – 2. 63.g). T he corr ect solutions f or t hese q uest ions were obt ained using Micr osof t SQ L Server 2012. T he Micr osof t Access r esult s wit hout t he O RDER BY clause ar e also shown, so you can assig n t hese problems wit hout t he O RDER BY par t of t he q uest ions.

Micr osof t Access 2013 does not suppor t SQ L wil dcar d char act er s ( see Revie w Q uest ions 2.36 – 2. 38), alt houg h it does have equiva lent wildcar d char acters as descr ibed in t he chapt er . T he corr ect so lutions f or t hese q uest ions were obt ained using Micr osof t SQ L Server 2012.

For t hose st udent s who are used t o procedural lang uag es, t hey m ay have som e init ial dif f icult y wit h a lang uag e t h at does set pr ocessing lik e SQ L. T hese st udent s are accust om ed t o pr ocessing r ows (r ecords) r at her t han set s. It is t im e we ll spent t o m ak e sur e they under st and t hat SQ L processes t ables at a t im e, not r ows at a t ime.

Chapt er T wo – Intr oduc t ion to S tr uc tured Q uer y La ngu St udent s age m ay have some tr ouble under st anding the G RO UP BY clause. If you can explain it in t er m s of t r adi t ional cont r ol br eak log ic ( sort r ows on a k ey then process t he r ows unt il the value of t he k ey changes) , t hey will ha ve less t rouble.

Chapt er T wo – Intr oduc t ion to S tr uc tured Q uer y La ngu age

T his also explains wh y t he G RO UP BY clause wil l present t he r ows sort ed even t houg h you do not use an O RDER BY clause.

At t his point, st udents f am iliar wit h Micr osof t Access will wonder wh y t hey are lear ning SQ L. They have m ade q uer ies in Micr osof t Access using Micr osof t Access' s version of Query- By- E xample ( Q BE), and t her ef or e never had t o under st and t he SQ L. I n m any cases, t hey will not k now t hat Micr osof t Access g ener ates SQ L code wh en you cr eat e a q uer y in desig n view. It is wort h let t ing t hem k now t his is done and even showing t hem t he SQ L cr eat ed f or and under lying a Micr osof t Access q uer y.

I t is also im port ant f or student s t o under st and t hat , in m any cases, t he Query - By- Example f orm s such as Micr osof t Access’ desig n vie w can be very inef f icient . Also, t he Q BE f or ms ar e not available f r om wit hin an application pr ogram such as Java or C, and so SQ L m ust be wr it t en.

It has been our exper ience t hat a r eview of a Cartesian Pr oduct f r om an alg ebr a class is t im e well spent. Show st udent s what will happen if a W HERE st atement is lef t of f of a j oin. T he f ollo wing example wil l work . Assum e you cr eat e f our t ables wit h f ive colu m ns each and 100 r ows each. How m any columns and r ows will be displa yed by t he st atem ent: SELECT * FROM TABLE1, TABLE2, TABLE3, TABLE4; T he r esult is 20 columns ( not bad) but 100,000, 000 r ows ( 100 * 100 = 10, 000, 10, 000 * 100 = 1,0 00, 000, 1, 000,000 * 100 = 100, 000,000) . T his happens because t he JO I N is not q ualif ied. If t hey understand Car t esian product s then t hey wi ll under st and how t o f ix a JO I N wher e t he result s ar e m uch t oo large.

Note t hat in t he Marcia' s Dr y Cleaning proj ect, wh ere in som e previous edit ions we have used t ables nam ed O RDER and O RDER_IT EM, we have changed t hese t able nam e s t o I NVO I CE and I NVO I CE_ITE M. W e did t his because O RDER is an SQ L r eserved word ( par t of O RDER BY) . T her ef ore, when the t able nam e O RDER is used as par t of a q uer y, i t m ay need t o be (" m ust be" in Access 2013) enclosed in delim it ers as [O RDER] if t he q uer y is g oing t o run corr ect ly. T he t opic of r eserved words and delim iters is discussed in m or e det ail in Chapt ers 6 and 7. Howe ver, now is a g ood t ime t o intr oduce it t o your st udent s.
