Description
The Oracle SQL DML and DDL course is the third in a three-part series covering the Data Manipulation and Data Definition language statements supported by Oracle9i. This course introduces the participants to various objects in a database. The participants learn to create, update, and delete the database objects. The participants also learn to add rows, update, and delete existing rows from a table. The course also explains the use of external tables and how to create the external tables.
Audience
The intended audience for this course are Database Administrators. Required prerequisite knowledge includes Oracle9i SQL: Basic SELECT Statements 61130 and Oracle9i SQL: Data Retrieval Techniques 61131.
