Introduction to Oracle9i: Advanced SQL

Course details

Essential advanced features within the Oracle SQL language are considered within this course. Building indexes, specifying declarative constraints, managing security privileges for tables and using SQL to satisfy some of the most complex query requests are all among the topics considered within this course. This course largely focuses on SQL features that are unique to the Oracle database and as such is applicable even for SQL professionals experienced in other databases.

• truncate
• difference from delete and drop table
• create index / drop index
• user_ind_columns
• alter view
• user_updatable_columns

• nextval, currval
• alter, drop sequence
• create synonym / drop synonym

DATABASE SECURITY:

• user schema pass_a

SQL FUNCTIONS (CHARACTER):

• character functions
• upper(), lower(), initcap()
