SQL Scripting: Level 2 - Querying & Manipulating Data


Description In 'SQL Scripting: Level 1 - Fundamentals of Querying', you examined the fundamentals of SQL querying. Because of various business conditions and requirements, in addition to querying the database, you may need to restructure and index tables. You may also need to manipulate the data in the tables. In this instructor-led course, you will create advanced SQL queries, and manipulate and index tables.

Students should have basic computer skills, SQL skills, and be familiar with concepts related to database structure and terminology.

Completion of SQL Scripting: Level 1 or equivalent knowledge recommended.

Learning Objectives
Upon successful completion of this course, students will be able to:

  • use subqueries to generate query output.
  • manipulate table data by inserting and updating records in a table and deleting records from a table.

  • create views, manipulate data through views, modify the view structure, and drop views.
  • create indices on table columns and drop inefficient indices.
  • mark the beginning of a transaction, create a savepoint within a transaction, rollback a transaction, and commit a transaction.
