Iconos de los componentes agrupados en la página Data Access
Esta página incluye componentes especialzados para acceso a bases de datos:
| DataSource | Acts as a conduit between a dataset component such as TTable and data-aware components such as TDBGrid. |
| Table | Retrieves data from a physical database table via the BDE and supplies it to one or more data-aware components through a DataSource component. Conversely, it also sends data received from a component to a physical database via the BDE. |
| Query | Uses SQL statements to retrieve data from a physical database table via the BDE and supplies it to one or more data-aware components through a TDataSource component. Conversely, uses SQL statements to send data from a component to a physical database via the BDE. |
| StoredProc | Enables an application to access server stored procedures. Sends data received from a component to a physical database via the BDE. |
| Database | Sets up a persistent connection to a database, especially a remote database requiring a user login and password. |
| Session | Provides global control over a group of Database components. A default TSession component is automatically created for each C++Builder database application. You must use the TSession component only if you are creating a multithreaded database application. Each database thread requires its own session component. |
| BatchMove | Copies a table structure or its data. Can be used to move entire tables from one database format to another. |
| UpdateSQL | Lets you use cached updates support with read-only datasets. For example, you could use a TUpdateSQL component with a "canned" query to provide a way to update the underlying datasets, essentially giving you the ability to post updates to a read-only dataset. You associate a TUpdateSQL component with a dataset by setting the dataset's UpdateObject property. The dataset automatically uses the TUpdateSQL component when cached updates are applied. |
| NestedTable | Retrieves the data in a nested dataset field and supplies it to data-aware controls through a datasource component. |
