data adapter

Allows you to create and configure parameters associated with a SQL statement or stored procedure in a data adapter.

A data adapter contains SQL commands that your application can use to read data into a dataset from a database and write it back again.

The same set of UI elements used to define the various data adapter commands are used in the standalone command editor.

If you want to see how the data adapter will fill a dataset, preview the results.

The AcceptChanges method is called automatically when calling the update methods of a TableAdapter or data adapter.

This example iterates through a data reader created using a data adapter's select command as well as maintaining a count of records read.

Configures SQL commands or stored procedures that a data adapter uses to read data into a dataset from a database and write it back again.

This allows you to pass arbitrary SQL commands through the data adapter, such as those used to define or modify database definitions.

A data adapter of type SqlDataAdapter called SqlDataAdapter1 configured with a connection and a Select command to retrieve data.

Each data adapter has select, update, insert, and delete commands that could be either SQL statements or a call to a stored procedure.

Your tests can be run, but the diagnostic data adapter cannot be run.

Data Adapter Configuration Wizard helps you set the properties of a new or existing data adapter.

Before an application can access data in a database, it needs to create a connection to the database and to configure a data adapter.

The designer adds an instance of the adapter to the form or component and launches the Data Adapter Configuration Wizard.

Displays one or more errors that occurred while Visual Studio was attempting to create an instance of a data adapter and set its properties.

Then, a data adapter (da) and a data set (ds) are created, and the data adapter is used to fill the data set with data.

Data Adapter Configuration Wizard runs you through the entire process of creating a data adapter (and, if necessary, a data connection).

Thirdly, makes some try on the realization of three key parts: the database of data share center, data adapter and data access interface.

The commands in a data adapter are usually parameter-driven.

That command builder is then used by the data adapter to update the modified DataSet in the local database.

You can use a Transact-SQL SELECT statement to select UDT column values to populate a dataset using a data adapter.

Each time you add a data adapter from the Toolbox, you rerun the wizard to configure that particular data adapter.

You can specify which applications to record in your test settings for the actions diagnostic data adapter.

If you intend to use a dataset that contains multiple tables, you will probably want to add more data adapter to your form or component.

Repeat the steps to create a data adapter without using the wizard as explained in the Add the Data Adapter to Fill the Tables List section.

This value is used during updates; the data adapter passes the value of a specific column to the update command.

In order to send the modified data to a database, you call the Update method of a TableAdapter or data adapter.

This class is created by the OleDb data adapter when an error occurs.

Generally speaking, if you want to create parameterized queries for the adapter, you should use the Data Adapter Configuration Wizard.

The Data Adapter Configuration Wizard provides the simplest and most flexible way to create data adapters.

You can also execute commands yourself, independently of the data adapter.

Call the Update method of each data adapter.

For details, see Parameters in Data-Adapter Commands.

If you are creating a new adapter, drag a data adapter object from the Toolbox onto a form or component.

Select the new Data Adapter and click on the Properties view.

Explains how to drag a data adapter from the Toolbox, and then configure it yourself using the Properties window.

A data adapter is part of what is known as a managed provider, which is a set of classes for a specific type of data source.

You fill the data tables by executing TableAdapter queries or by executing data adapter (for example, SqlDataAdapter) commands.

To allow you to pass parameter values at run time, each of the four command objects for a data adapter supports a

A data adapter needs an open connection to a data source to read and write data.

Part of configuring the data adapter involves establishing table mappings between tables in the data source and the dataset.

To submit changes made in a DataSet back to the data source, you can use the Update method of a data adapter.

Generally, each data adapter exchanges data between a single data-source table and a single
