SQL Querying: Advanced Training in United Kingdom

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.

You will:

• Use nested queries to generate query output.
• Manipulate table data by inserting and updating records in a table and deleting records from a table.
• 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.
