1 Andmebaasid Praktikum 7 (kordamine)
2 Ülesande püstitus Luua andmebaas õppeainete ning õppimisega seotud andmete hoidmiseks ja kasutamiseks.
3 ANDMETE FÜÜSILINE MUDEL
4
5 Ülesanded Loo andmebaas nimega edu ja järgnevad tabelid oma andmebaasi CREATE TABLE Faculty( Id INTEGER NOT NULL DEFAULT AUTOINCREMENT PRIMARY KEY, Name VARCHAR(50) NOT NULL, Address VARCHAR(30), DeanId INTEGER, ViceDeanId INTEGER, UNIQUE(Name) );
6 Ülesanded CREATE TABLE Person( Id INTEGER NOT NULL DEFAULT AUTOINCREMENT PRIMARY KEY, FirstName VARCHAR(30) NOT NULL, LastName VARCHAR(30) NOT NULL, FacultyId INTEGER NOT NULL, SSN VARCHAR(11), UNIQUE(FirstName,LastName)); CREATE TABLE Registration( Id INTEGER NOT NULL DEFAULT AUTOINCREMENT PRIMARY KEY, CourseId INTEGER NOT NULL, PersonId INTEGER NOT NULL, FinalGrade VARCHAR(1));
7 Ülesanded CREATE TABLE Lecturer( Id INTEGER NOT NULL DEFAULT AUTOINCREMENT PRIMARY KEY, CoursesId INTEGER, PersonsId INTEGER NOT NULL, Responsible SMALLINT); CREATE TABLE Course( Id INTEGER NOT NULL DEFAULT AUTOINCREMENT PRIMARY KEY, FacultyId INTEGER NOT NULL, Name VARCHAR(50) NOT NULL, Code VARCHAR(20), EAP INTEGER, GradeType VARCHAR(8));
8 INPUT näited INPUT INTO Person FROM 'person.txt' FORMAT ASCII DELIMITED BY '\x09' INPUT INTO Faculty FROM 'faculty.txt' FORMAT ASCII DELIMITED BY '\x09'
9 Ülesanded Analoogselt näidetega impordi sama nimega failidest ka järgnevad tabelid: Registration Lecturer Course Failid saab alla laadida Moodle i keskkonnast.
10 FK näidis ALTER TABLE Registration ADD CONSTRAINT fk_registration_person FOREIGN KEY (PersonId) REFERENCES Person (Id) ON DELETE CASCADE ON UPDATE CASCADE; Person tabeli kirje kustutamisel kustutatakse tema registreeringud ainetele ALTER TABLE Faculty ADD CONSTRAINT fk_faculty_person_dean FOREIGN KEY (DeanId) REFERENCES Person (Id) ON DELETE SET NULL ON UPDATE CASCADE; Dekaani kirje kustutamisel ei kustutata tema teaduskonda
11 Ülesanne Luua lisaks näidetele kuus välisvõtit nii, et ülemtabeli kirje kustutamisel kustutatakse ka alamtabeli vastavad kirjed, va kahel erandjuhul, kui seos tühistatakse: Registration Course Lecturer Person Lecturer Course (tühista seos) Course Faculty Faculty (ViceDeanId) Person (tühista seos) Person Faculty
12 PÄRINGUD
13 Alampäringud Dekaanid teaduskondadest, kus oli olemas ka prodekaan: SELECT * FROM person WHERE EXISTS ( SELECT * FROM faculty WHERE faculty.deanid = person.id AND faculty.vicedeanid IS NOT NULL )
14 Mitme tabeli sidumine päringusse SELECT firstname, lastname, name, faculty.id, DeanId FROM person, faculty WHERE firstname = 'Mati' AND deanid = person.id
15 Grupeerimine Kui palju on iga EAP väärtusega aineid? SELECT eap, count(*) FROM course GROUP BY eap Kui palju on igale kursusele registreerunud inimesi? SELECT name, count(*) FROM course, registration WHERE course.id = registration.courseid GROUP BY course.name
16 Grupeerimine Kui palju on sama tähega algavaid perekonnanimesid? SELECT LEFT(lastName,1) AS pn, COUNT(*) AS arv FROM person GROUP BY pn ORDER BY arv DESC, pn ASC;
17 Mitu päringut üks tulemus Millist tähte kasutatakse enam nime alguses? Vaadelda nii pere- kui ka eesnimesid. Järjestada tulemus nime algustäht, esinemiste arv ja p või e (perenimi / eesnimi) mitte kasvavalt korduste arvu järgi. SELECT LEFT(lastName,1), COUNT(*),'p' FROM person GROUP BY LEFT(lastName,1) UNION ALL SELECT LEFT(firstName,1), COUNT(*),'e' FROM person GROUP BY LEFT(firstName,1) ORDER BY 2 DESC, 1;
18 Näited CREATE VIEW v_oigusteaduskonna_opilased AS SELECT * FROM person WHERE facultyid = 2 CREATE VIEW v_oigusteaduskonna_opilased_mini (eesnimi,perenimi) AS SELECT FirstName, LastName FROM person WHERE facultyid = 2 CREATE VIEW v_persons_faculty AS SELECT p.firstname, p.lastname, f.name as FacultyName, f.address as FacultyAddress FROM person as p JOIN faculty as f ON (p.facultyid = f.id)
19 Näited CREATE VIEW v_faculty_deans (FacultyName, DeanName, ViceDeanName) AS SELECT f.name, d.firstname+' '+d.lastname as deanname, v.firstname+' '+v.lastname as vicedeanname FROM Faculty as f JOIN Person as d ON (f.deanid = d.id) JOIN Person as v ON (f.vicedeanid = v.id) ORDER BY f.name
20 Näited Lisame uue kursuse "Sissesjuhatus informaatikasse" INSERT INTO Course VALUES (101,9,'Sissejuhatus informaatikasse', MTAT ',3,'Arvestus') Lisame kursusele samad inimesed kes osalevad kursusel Sissejuhatus ettevõtte majandusse INSERT INTO registration (CourseId,PersonId,FinalGrade) SELECT 101, p.id, NULL FROM Course as c JOIN Registration as r ON (c.id = r.courseid) JOIN Person as p ON (r.personid = p.id) WHERE c.name = 'Sissejuhatus ettevõttemajandusse'
21 Näited Kuvame mõlemal kursusel õppivad õpilased SELECT p.firstname+' '+p.lastname as PersonName, c.name as CourseName FROM Course as c JOIN Registration as r ON (r.courseid = c.id) JOIN Person as p ON (r.personid = p.id) WHERE c.id = 101 OR c.id = 75 ORDER BY PersonName
22 Ülesanded 1. Luua vaade v_persons_atleast_4eap (FirstName, LastName) õpilastest, kes õpivad Matemaatika-informaatikateaduskonna ainetel, mis annavad vähemalt 4 EAP-d 2. Luua vaade v_mosta(firstname, LastName, NrOfA) õpilastest, kes on saanud kõige rohkem A-sid Matemaatika-informaatikateaduskonna ainetest 3. Luua uus kursus "Andmebaaside teooria". Matemaatika-informaatikateaduskond, MTAT , 6EAP, Arvestus Lisada sinna kõik õpilased, kes said aines Andmebaasid A või B
23 Ülesanded 4. Luua vaade v_andmebaasideteooria õpilastest, kes õpivad ainet andmebaaside teooria. (PersonId, FirstName, LastName) 5. Luua vaade v_top20a (FirstName, LastName, nrofa) päringule TOP 20 õpilastest, kes on saanud kõige rohkem A-sid. Järjestada saadud nimekiri ka perenimede järgi. 6. Luua vaade v_top20students(firstname, LastName, AvarageGrade) päringule TOP 20 õpilastest, kelle keskmine hinne on kõige kõrgem. Järjestada saadud nimekiri ka perenimede järgi.
A basic create statement for a simple student table would look like the following.
Creating Tables A basic create statement for a simple student table would look like the following. create table Student (SID varchar(10), FirstName varchar(30), LastName varchar(30), EmailAddress varchar(30));
