An Introduction to Data. Set in VB. NETMuch of Microsofts data technology, ADO. NET, is provided by the Data. Set object. This object reads the database and creates an in memory copy of that part of the database that your program needs. A Data. Set object usually corresponds to a real database table or view, but Data. Set is a disconnected view of the database. After ADO. NET creates a Data. Set, there is no need for an active connection to the database, which helps in scalability because the program only has to connect with a database server for microseconds when reading or writing. In addition to being reliable and easy to use, Data. Set supports both a hierarchical view of the data as XML and a relational view that you can manage after your program disconnects. You can create your own unique views of a database using Data. Set. Relate Data. Table objects to each other with Data. Relation objects. You can even enforce data integrity using the Unique. Constraint and Foreign. Key. Constraint objects. The simple example below uses only one table, but you can use multiple tables from different sources if you need them. Coding a VB. NET Data. Set. This code creates a Data. Set with one table, one column and two rows Dim ds As New Data. Set. Dim dt As Data. Table. Dim dr As Data. Row. Dim cl As Data. Column. Dim i As Integer. New Data. Table.

Rows. Count 1. Console. Write. Line. Tables0. Rowsi. Item0. To. String. The most common way to create a Data. Set is to use the Fill method of the Data. Adapter object. Heres a tested program example Dim connection. String As String. Data SourceMUKUNTUWEAP amp. Initial CatalogBooze amp. Integrated SecurityTrue. Dim cn As New Sql. Connectionconnection. String. Dim command. Wrapper As Sql. Command. New Sql. CommandSELECT FROM RECIPES, cn. Dim data. Adapter As Sql. Data. Adapter. New Sql. Data. Adapter. Dim my. Data. Set As Data. Set New Data. Set. Adapter. Select. Command. Wrapper. data. Adapter. Fillmy. Data. Set, Recipes. The Data. Set can then be treated like a database in your program code. The syntax doesnt require it, but you will normally provide the name of the Data. Table to load the data into. Heres an example showing how to display a field. Dim r As Data. Row. For Each r In my. Data. Set. TablesRecipes. Rows. Console. Write. LinerRecipe. Name. To. String. Although the Data. Set is easy to use, if raw performance is the goal, you might be better off writing more code and using the Data. Reader instead. If you need to update the database after changing the Data. Set, you can use the Update method of the Data. Adapter object, but you have to make sure that the Data. Adapter properties are set correctly with Sql. Command objects. Sql. Command. Builder is usually used to do this. Dim obj. Command. Builder As New Sql. Command. Builderdata. Adapter. data. Adapter. Updatemy. Data. Set, Recipes. Data. Adapter figures out what has changed and then executes an INSERT, UPDATE, or DELETE command, but as with all database operations, updates to the database can run into problems when the database is being updated by other users, so you often need to include code to anticipate and solve problems when changing the database. Sometimes, only a Data. Set does what you need. If you need a collection and youre serializing the data, a Data. Set is the tool to use. You can quickly serialize a Data. Set to XML by calling the Write. XML method. Data. Set is the most likely object you will use for programs that reference a database. Its the core object used by ADO. NET, and it is designed to be used in a disconnected mode.
