1 Oracle Database: SQL and PL/SQL Fundamentals Certfcaton Course 1

2 Duraton: 5 Days (30 hours) What you wll learn: Ths Oracle Database: SQL and PL/SQL Fundamentals tranng delvers the fundamentals of SQL and PL/SQL along wth the benefts of the programmng languages usng Oracle Database technology. Benefts to You: By takng ths course, you'll be able to create and manpulate relatonal data bases usng SQL and PL/SQL. Ths course s also an excellent method of preparng to take the Oracle Database Foundatons Certfed Junor exam. Audence: PL/SQL Developer Data Base Admnstrator Prerequstes Famlarty wth Relatonal Data Concepts Famlarty wth programmng concepts 1

3 Course Objectves: * Run data manpulaton statements (DML) to update data n the Oracle Database. * Desgn PL/SQL anonymous block that execute effcently. * Descrbe the features and syntax of PL/SQL. * Handle runtme errors. * Descrbe stored procedures and functons. * Use PL/SQL programmng constructs and condtonally control code flow (loops, control structures, and explct cursors). * Use cursors to process rows. * Identfy the major structural components of the Oracle Database 11g. * Retreve row and column data from tables wth the SELECT statement. * Create reports of sorted and restrcted data. * Employ SQL functons to generate and retreve customzed data. * Dsplay data from multple tables usng the ANSI SQL 99 JOIN syntax. * Create reports of aggregated data. * Run data defnton language (DDL) statements to create and manage schema objects. 1

5 Usage of Sngle-Row Functons to Customze Output: Lst the dfferences between sngle row and multple row functons Manpulate strngs usng character functons Manpulate numbers wth the ROUND, TRUNC, and MOD functons Perform arthmetc wth date data Manpulate dates wth the DATE functons Converson Functons and Condtonal Expressons: Descrbe mplct and explct data type converson Descrbe the TO_CHAR, TO_NUMBER, and TO_DATE converson functons Nestng multple functons Apply the NVL, NULLIF, and COALESCE functons to data Usage of condtonal IF THEN ELSE logc n a SELECT statement Aggregated Data Usng the Group Functons: Usage of the aggregaton functons n SELECT statements to produce meanngful reports Descrbe the AVG, SUM, MIN, and MAX functon How to handle Null Values n a group functon? Dvde the data n groups by usng the GROUP BY clause Exclude groups of date by usng the HAVING clause SELECT * FROM table_name; 1

6 Dsplay Data From Multple Tables: Wrte SELECT statements to access data from more than one table Jon Tables Usng SQL:1999 Syntax Vew data that does not meet a jon condton by usng outer jons Jon a table to tself by usng a self jon Create Cross Jons Usage of Subqueres to Solve Queres: Use a Subquery to Solve a Problem Sngle-Row Subqueres Group Functons n a Subquery Multple-Row Subqueres Use the ANY and ALL Operator n Multple-Row Subqueres Use the EXISTS Operator SET Operators: Descrbe the SET operators Use a SET operator to combne multple queres nto a sngle query Descrbe the UNION, UNION ALL, INTERSECT, and MINUS Operators Use the ORDER BY Clause n Set Operatons James Carter IT department 1

11 Important Informaton: All certfcates ssued by the Insttute bearng check code Student must verfy the nsttute valdaton of the certfcate by typng the check code n the followng lnk: In case the certfcate has been verfed that means t has a data and that the certfcate s consdered vald. If no data occurs, student should mmedately contact and check on the certfcate valdaton wth the Insttute General department through the followng e-mal address: student@olsa.no All cards ssued by the Insttute bearng a code and a specfc number as well Student must check the card valdty ssued by the Insttute through the followng lnk: In case the certfcate has been verfed, that means the card has a data and so t s a vald card. f no data occurs, student should mmedately contact and check on the certfcate valdaton wth the Insttute General department through the followng e-mal address: student@olsa.no 1
