...DD1334 Databasteknik Laboration 1: SQL Basics Andreas Gustafsson, Hedvig Kjellström, Michael Minock and John Folkesson The purpose of Laboration 1 is to learn how to retrieve rmation stored in relational databases. You will learn 1) how to formulate SQL queries and understand how they apply to the schema and how they are executed; 2) how constraints effect insertions and deletions; 3) about the basics of view, transactions, indices and triggers. The recommended reading for Laboration 1 is that of Lectures 1-7 , particularly Chap 6-8. Laboration Come prepared to the review session! Only one try is allowed – if you fail, you are not allowed to try again until the next lab session. The review will take 10 minutes or less, so have all papers in order. To pass you should have Completed Task 1 with at least 9 of the 10 queries right, completed Task 2 and able to explain why certain actions give errors and other do not, also 8 of the 9 steps should be documented showing you executed them correctly, Task 3 the output file should show that the trigger works as it should. The grade is A if passed when the review when due. See the Lab Grading page in bilda contents for the due dates for the labs and the grading of late assignments. Laboration 1 is intended to take 30h to complete. Computing Environment In this assignment you will use Nestor 2.0. Nestor is KTH’s logic engine (computer) dedicated to hold the databases used in this and other similar courses. Nestor is aptly named after...

...INTRODUCTION SQL is divided into the following Data Definition Language (DDL) Data Manipulation Language (DML) Data Retrieval Language (DRL) Transaction Control Language (TCL) Data Control Language (DCL) DDL -- create, alter, drop, truncate, rename DML -- insert, update, delete DRL -- select TCL -- commit, rollback, savepoint DCL -- grant, revoke CREATE TABLE SYNTAX Create table (col1 datatype1, col2 datatype2 …coln datatypen); Ex: SQL> create table student (no number (2), name varchar (10), marks number (3)); INSERT This will be used to insert the records into table. We have two methods to insert. a) By value method By address method USING VALUE METHOD Syntax: insert into (table_name) values (value1, value2, value3 …. Valuen); © Copy rights are reserved. 2 Ex: SQL> insert into student values (1, ’sudha’, 100); SQL> insert into student values (2, ’saketh’, 200); To insert a new record again you have to type entire insert command, if there are lot of records this will be difficult. This will be avoided by using address method. b) USING ADDRESS METHOD Syntax: insert into (table_name) values (&col1, &col2, &col3 …. &coln); This will prompt you for the values but for every insert you have to use forward slash. Ex: SQL> insert into student values (&no, '&name', &marks); Enter value for no: 1 Enter value for name: Jagan Enter value for marks: 300 old new SQL> 1:...

...C H A P T E R 3 SQL Chapter 3 covers the relational language SQL. The discussion is based on SQL:1999. Integrity constraint and authorization features of SQL being a large language, many of its features are not covered here, and are not appropriate for an introductory course on databases. Standard books on SQL, such as Date and Darwen [1993] and Melton and Simon [1993], or the system manuals of the database system you use can be used as supplements for students who want to delve deeper into the intricacies of SQL. Although it is possible to cover this chapter using only handwritten exercises, we strongly recommend providing access to an actual database system that supports SQL. A style of exercise we have used is to create a moderately large database and give students a list of queries in English to write and run using SQL. We publish the actual answers (that is the result relations they should get, not the SQL they must enter). By using a moderately large database, the probability that a “wrong” SQL query will just happen to return the “right” result relation can be made very small. This approach allows students to check their own answers for correctness immediately rather than wait for grading and thereby it speeds up the learning process. A few such example databases are available on the Web home page of this book. Exercises that pertain to database design are best deferred until after Chapter 7. Exercises 3.8 Consider the insurance database of Figure 3.11, where...

...you need to return a backup of your database in the form of sql scripts. Create a zip file packaging everything together and upload this .zip file on the Blackboard. The deadline is March 4th, 2015 Each day of late delivery will cost you a penalty of -25%. You are expected to use an SQL DBMS software (preferably MySQL server) to design your database and then transfer your code in a word/latex document. This document has to be editable. Do not upload pdf files because it is not easy for us to copy-paste your contents while grading. Please also deliver, within your document, the output of the queries. For each one of the tasks there is included very detailed information about the delivery requirements, which you have to read very carefully.

...SQL Cursor A SQL cursor is a private Oracle SQL working area. There are two types of SQL cursor: implicit or explicit cursor. The implicit cursor is used by Oracle server to test and parse the SQL statements and the explicit cursors are declared by the programmers. Using the implicit cursor, we can test the outcome of SQL statements in PL/SQL. For example, • SQL%ROWCOUNT, return the number of rows affected; • SQL%FOUND, a BOOLEAN attribute indicating whether the recent SQL statement matches to any row; • SQL%NOTFOUND, a BOOLEAN attribute indicating whether the recent SQL statement does not match to any row; • SQL%ISOPEN, a BOOLEAN attribute and always evaluated as FALSE immediately after the SQL statement is executed. To write the explicit cursor, please refer to the following example. Note that a cursor definition can array a number of arguments. For example, DECLARE CURSOR csr_ac (p_name VARCHAR2) IS SELECT empno, name, sal FROM employee WHERE name LIKE '%p_name%'; BEGIN FOR rec_ac IN csr_ac ('LE') LOOP DBMS_OUTPUT.PUT_LINE(rec_ac.empno || ' ' ||rec_ac.name || ' '||v_sal); END LOOP ; CLOSE csr_ac; END; / Another way of writing the above code, is to use the basic loop and the SQL%NOTFOUND cursor, as shown in the following. SQL> DECLARE 2 CURSOR csr_ac (p_name VARCHAR2) IS 3 SELECT empno, ename, sal 4 FROM emp 5 6 WHERE ename LIKE '%SMITH%'; 7 8 v_a emp.empno%TYPE; ...

...reality in a way that supports processes requiring information. For example, modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies. Database management systems (DBMSs) are computer software applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL,Microsoft SQL Server, Oracle, SAP and IBM DB2. A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such asSQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database modelthat they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language. Sometims a DBMS is loosely referred to as a "database". database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images. In computing, databases are sometimes classified according to their organizational approach. The most prevalent approach is therelational database, a tabular database in which data is defined so that it can be reorganized...
