How to multiple tables in Dataset - Sql Server
The DataSet is a data structure that holds a collection of DataTable objects and their corresponding DataRelationCollection. Each DataTableCollection can contain zero or more DataTable objects, which represent individual tables of data. The SqlDataAdapter, an object provided by ADO.NET, enables us to populate these DataTables within a DataSet. To accomplish this, we can utilize the Fill method of the SqlDataAdapter, which retrieves data from a data source and populates the specified DataTables in the DataSet.
Store data from multiple tables simultaneously
In situations where we need to retrieve and store data from multiple tables simultaneously, we can use the capabilities of the SqlDataAdapter. By providing a single SqlDataAdapter object and specifying multiple SQL statements or commands, we can populate the Dataset with multiple tables in a single operation. This approach saves us from making separate database calls for each table and improves efficiency.
To illustrate this, consider the following VB.NET code snippet:Full Source VB.NET
The SqlDataAdapter provides a powerful mechanism for populating DataTables in a DataSet, allowing us to retrieve and store data from multiple tables in a single operation.
