Updating database from datagridview vb net
To insert, update, and delete data using a Data Adapter, you create an Ole Db Command object with INSERT, UPDATE, and DELETE statements and set the Insert Command, Update Command, and Delete Command properties of the data adapter to Ole Db Command.
You can avoid building Command objects manually by using Command Builder.
The Display Data() method fills in the data in the Data Grid View.
Bind variables are placeholders inside a SQL statement.
When a connection is established with the database, the data adapter creates a dataset and stores data in it. Click Dim connection As Sql Connection = New sqlconnection() connection.
After the data is retrieved and stored in a dataset, the connection with the database is closed. The dataset works as a virtual database containing tables, rows, and columns. Connection String = "Data Source=KABIR-DESKTOP; _ Initial Catalog=test DB; Integrated Security=True" connection. Tables(0) End Sub End Class We have discussed that the Data Set components like Data Table, Data Column and Data Row allow us to create tables, columns and rows, respectively.
For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.
Note: Keep in mind that this Update is different than a SQL UPDATE statement.
