Course objectives, agenda, and appendixes used in the course Overview of Oracle Database 12c and related products Overview of relational database management concepts and terminologies Introduction to SQL and its development environments The Human Resource(HR) Schema and the tables used in the Course Start Oracle SQL Developer and create a new connection to the ora1 account. Use Oracle SQL Developer to examine the data objects in the ora1 account. The ora1 account contains the HR schema tables. Lesson 2: Retrieving Data Using the SQL SELECT Statement This lesson describes the capabilities of the SQL SELECT statement, and how to execute a basic SELECT statement. Basic SELECT statement Arithmetic expressions and NULL values in the SELECT statement Column Aliases Use of concatenation and alternative quote operators, literal character strings and the DISTINCT keyword Using the DESCRIBE command Selecting all data from different tables Describing the structure of tables Performing arithmetic calculations and specifying column names Lesson 3: Restricting and Sorting Data This lesson explains the use of operators to limit and sort the rows returned by a query. It also describes the use of ampersand substitution variables to restrict and sort output at run time. Limiting rows with the WHERE clause, comparison conditions, the NULL and logical operators Rules of precedence for operators in an expression Sorting rows using the ORDER BY clause SQL row limiting clause in a query Using Substitution Variables Using the DEFINE and VERIFY commands Selecting data and changing the order of the rows that are displayed Restricting rows by using the WHERE clause Sorting rows by using the ORDER BY clause Using substitution variables to add flexibility to your SQL SELECT statements Lesson 4: Using Single-Row Functions to Customize Output This lesson describes the nature of various types of functions available in the SQL language. It also demonstrates the use of character, number and date functions in SELECT statements. Single-row SQL functions Character functions Number functions Working with dates Date functions Writing a query that displays the current date Creating queries that require the use of numeric, character, and date functions Performing calculations of years and months of service for an employee Lesson 5: Using Conversion Functions and Conditional Expressions This lesson describes the use of various types of conversion functions available in SQL. It also demonstrates the use of the TO_CHAR, TO_NUMBER and TO_DATE functions and how to apply conditional expressions in a SELECT statement. Implicit and explicit data type conversion TO_CHAR, TO_DATE, TO_NUMBER functions Nesting functions General functions: o NVL o NVL2

3 o NULLIF o COALESCE Conditional expressions o CASE o DECODE Creating queries that use TO_CHAR, TO_DATE, and other DATE functions Creating queries that use conditional expressions such as DECODE and CASE Lesson 6: Reporting Aggregated Data Using the Group Functions This lesson explains the use of group functions in obtaining summary information for groups of rows. It also discusses how to group rows into smaller sets and how to specify search criteria for groups of rows. Group functions o Types and syntax o Use AVG, SUM, MIN, MAX, COUNT o Use the DISTINCT keyword within group functions o NULL values in a group function Grouping rows o GROUP BY clause o HAVING clause Nesting group functions Writing queries that use the group functions Grouping by rows to achieve more than one result Restricting groups by using the HAVING clause Lesson 7: Displaying Data from Multiple Tables Using Joins This lesson explains how to obtain data from multiple tables through the use of joins. It demonstrates the use of equijoins, nonequijoins, selfjoins, outer joins in SELECT statements as well as the generation of Cartesian products with a cross join. Types of JOINS and its syntax Natural join o USING clause o ON clause Self-join Nonequijoins OUTER join o LEFT OUTER join o RIGHT OUTER join o FULL OUTER join Cartesian product o Cross join Joining tables using an equijoin Performing outer and self-joins Adding conditions Lesson 8: Using Subqueries to Solve Queries This lesson describes the use of subqueries in SQL statements as well as the different types and the types of problems that can be solved. Subquery types, syntax, and guidelines Single-row subqueries o Group functions in a subquery o HAVING clause with subqueries Multiple-row subqueries o Use ALL or ANY operator o Using the EXISTS operator Null values in a subquery Creating subqueries to query values based on unknown criteria Using subqueries to find out the values that exist in one set of data and not in another Lesson 9: Using the Set Operators This lesson demonstrates the use of set operators to combine or compare the results of many individual queries into a single result. Set Operators: Types and guidelines UNION and UNION ALL operator INTERSECT operator MINUS operator Matching the SELECT statements Using the ORDER BY clause in set operations Create reports by making us of: The UNION operator The INTERSECT operator The MINUS operator Lesson 10: Manipulating Data This lesson describes the use of each of the data manipulation statements. It also demonstrates how to insert, update and delete table data and how to control database transactions. Adding new rows in a table o INSERT statement Changing data in a table o UPDATE statement Removing rows from a table o DELETE statement o TRUNCATE statement Database transactions control using COMMIT, ROLLBACK and SAVEPOINT Read consistency FOR UPDATE clause in a SELECT statement

4 Inserting rows into the tables Updating and deleting rows in the table Controlling transactions Lesson 11: Introductions to Data Definition Language This lesson explains the use of data definition language (DDL) statements to create, alter and remove simple tables. It also shows the column data types available in DDL and introduces database schema concepts as well as table and column constraints. Database objects o Naming rules CREATE TABLE statement o Access another user s tables o DEFAULT option Data types Overview of the NOT NULL, UNIQUE, PRIMARY KEY, FOREIGN KEY and CHECK constraints Creating a table using a subquery ALTER TABLE o Read-only tables DROP TABLE statement Creating new tables Creating a new table by using the CREATE TABLE AS syntax Verifying that tables exist Altering tables Adding columns Dropping columns Setting a table to readonly status Dropping tables Fundamentals Lesson 1: Introduction This lesson provides an overview of the database schema and tables used in the course as well as a review of the basic concepts of the SQL language.
