Oracle Database 10g: SQL Fundamentals I

Duration: 3 Days

What you will learn

This course offers students an introduction to Oracle Database 10g database technology. In this class, students learn

the concepts of relational databases and the powerful SQL programming language. This course provides the essential

SQL skills that allow developers to write queries against single and multiple tables, manipulate data in tables, create

database objects, and query meta data.

Demonstrations and hands-on practices reinforce the fundamental concepts.

Learn to:

Use SQL Statements to retrieve data from tables

Create and Manage Tables

Employ SQL functions to generate and retrieve customized data

Run data manipulation statements (DML) to update data in the Oracle Database 10g

Aggregating Data Using Group FunctionsCategorize the Types of Group FunctionsUse the AVG, SUM, MAX, MIN, and COUNT Functions in a QueryUtilize the DISTINCT Keyword with the Group FunctionsDescribe how Nulls are handled with the Group FunctionsCreate Groups of Data with the GROUP BY ClauseGroup Data by more than one columnAvoid Illegal Queries with the Group FunctionsExclude Groups of Data with the HAVING Clause

Displaying Data from Multiple TablesIdentify Types of JoinsRetrieve Records with Natural JoinsUse Table Aliases to write shorter code and explicitly identify columns from multiple tablesCreate a Join with the USING clause to identify specific columns between tablesUse the ON clause to specify arbitrary conditions or specify columns to JoinCreate a Three-way join with the ON clause to retrieve information from 3 tablesList the Types of Outer Joins LEFT, RIGHT, and FULLGenerating a Cartesian Product

Using SubqueriesUse a sub query to solve a problemIdentify where sub queries can be placed in a SELECT statementDescribe the types of sub queries (single row, multiple row)Show the single row sub query operatorsUse the group functions in a sub queryIdentify illegal statements with sub queriesShow the multiple row sub query operatorsExplain how null values are handled in sub queries

Using the Set OperatorsUse the UNION operator to return all rows from multiple tables and eliminate any duplicate rowsUse the UNION ALL operator to return all rows from multiple tables (with duplicates)Describe the INTERSECT operatorUse the INTERSECT operatorExplain the MINUS operatorUse the MINUS operatorList the SET operator guidelinesOrder results when using the UNION operator

Inserting and Updating DataWrite INSERT statements to add rows to a tableInsert Special ValuesCopy Rows from Another TableUpdate Rows in a Table

Deleting DataUse DELETE statements to remove rows from a table
