Dataset updating multiple tables
Right-click on the Designer, select the Add option from the context menu, and pick the Table Adapter menu item. This will run the stored procedure and show its results in the Output window (see Figure 9). Alternatively, we could have added these columns manually to the Data Table. NET books and founder of 4Guys From Rolla.com, has been working with Microsoft Web technologies since 1998. or via his blog, which can be found at On Writing. This tutorial series was reviewed by many helpful reviewers. Note The feedback system for this content will be changing soon.

Figure 9: The Stored Procedures Results are Displayed in the Output Window (Click to view full-size image) At this point, the We have explored manually adding Data Table columns in previous tutorials, including Master/Detail Using a Bulleted List of Master Records with a Details Data List and Uploading Files, and we will look at this process again in more detail in our next tutorial. We will explore manually adding columns to the Data Table in the next tutorial. Scott works as an independent consultant, trainer, and writer. Lead reviewers for this tutorial were Hilton Geisenow, David Suru, and Teresa Murphy. For more information on the upcoming change, we invite you to read our blog post.Figure 5: Select the Create new stored procedures Option (Click to view full-size image) Use the following properties are correctly configured to call the corresponding stored procedures. This brings up the Table Adapter Configuration wizard, which lists the stored procedures used for selecting, inserting, updating, and deleting, along with their return values and parameters (if any). Here we can see that the stored procedure is in effect and that the insert, update, and delete capabilities of the Table Adapter are still functional, let s create a web page that allows users to view and delete employees. Figure 8: The Table Adapter Includes Insert, Update, and Delete Capabilities (Click to view full-size image) With the insert, update, and delete stored procedures automatically created and the values. Before we create such a page, however, we need to first create a new class in the Business Logic Layer for working with employees from the using System; using System. I make every attempt to define the terms correctly, however the definitions are my own.Sometimes I may be wrong and sometimes I may do a poor job of explaining the term.As Figure 5 depicts, have the wizard create new stored procedures and click Next. For this tutorial, however, let s use the automatic approach via the Table Adapter Configuration wizard.
When building a Data Access Layer using Typed Data Sets, the tools work better when using subqueries. Over the next several steps we will create a Table Adapter that, initially, uses a main query that omits any that returns additional columns from related tables. Fortunately, Table Adapters created using stored procedures do not suffer from the same brittleness as those created using ad-hoc SQL statements.Particle swarm optimisation (PSO) is an efficient evolutionary computation technique.However, the traditional personal best and global best updating mechanism in PSO limits its performance for feature selection and the potential of PSO for feature selection has not been fully investigated.In this tutorial we compare correlated subqueries and the JOIN syntax before looking at how to create a Table Adapter that includes a JOIN in its main query. First, instruct the Grid View to provide deleting capabilities by checking the Enable Deleting option from its smart tag.With relational databases the data we are interested in working with is often spread across multiple tables. Supplier ID s and correlated subqueries can both be used to retrieve related data from other tables, many developers are left scratching their heads and wondering which approach to use. Second, change the Object Data Source s table, causing the delete to fail.

Benefiting from the favorable property of the proposed many-to-one encoder, cross-dataset action data are encouraged to possess identical encoded features if the actions share the same class labels.
