Pre-requisites

A good working knowledge of Delphi. Our Delphi Fundamentals provides a solid base for this course. Some knowledge of SQL statements is beneficial, but not required.

Course Benefits

The Delphi SQL Server training class emphasizes productivity, performance, and application integrity. You will use Delphi specific features such as visual form inheritance, data modules, and the repository to drastically cut development time. You will also learn how to optimize SQL Server applications by understanding access plans & indexes, and by writing stored procedures, triggers, and validation at the server.

You Will Learn How To

• Make good use of the database tools and components in Delphi
• Use MS-SQL Server tools to create databases, tables and to specify integrity rules
• Program in Transact SQL
• Develop multi-table, multi user applications employing a wide range of controls and tools – to be deployed against SQL Server databases
• Design SQL Server c/s databases
• Write stored procedures & triggers in Transact SQL
• Manage database integrity violations in your Delphi application
• Optimize SQL Server databases
• Use ADO components to work with SQL Server
