Validating database query results
You will then create a simple query to list customers who are located in London.This walkthrough is code-oriented by design to help show LINQ to SQL concepts.Updated: May 13, 2016Applies To: System Center 2012 SP1 - Orchestrator, System Center 2012 - Orchestrator, System Center 2012 R2 Orchestrator The Query Database activity queries a database and returns the resulting rows as published data. Note: If you specify an invalid user name or password, the account assigned to the runbook server will be used to run the activity.This activity supports the following database types: The Query Database activity can be used to query a database for the detailed description of an error code that has appeared on one of the systems in the data center and then that description is sent to an administrator in an email message. The Visual Studio edition that you have and the settings that you use determine these elements. This walkthrough uses assemblies that might not be installed by default in your project. In this step you use a Data Context object to establish a connection between your code-based data structures and the database itself.The Data Context is the main channel through which you retrieve objects from the database and submit changes.This is a Transact-SQL statement that can be simple or quite complex depending on which clauses are applied to the SELECT statement.
Database testing mainly takes place at this layer and involves testing strategies such as quality control and quality assurance of the product databases.Database testing usually consists of a layered process, including the user interface (UI) layer, the business layer, the data access layer and the database itself.
