SQL Querying: Advanced Training in Hong Kong

Students should have a foundational understanding of SQL querying, basic computer skills and SQL skills, and be familiar with concepts related to database structure and terminology.

• Manipulate table structure.
• Create views, manipulate data through views, modify the view structure, and drop views.
• Create indexes on table columns and drop inefficient indexes.
• Mark the beginning of a transaction, roll back a transaction, and commit a transaction.
