Imports System.Data.SqlClient Next, you need to create a SqlConnection object, which represents the connection to the SQL Server database:
To prevent SQL injection attacks, it’s recommended to use parameterized queries. You can use the SqlParameter class to add parameters to your query: vb.net code to retrieve data from sql server
Dim sqlCommand As New SqlCommand("SELECT * FROM myTable WHERE column1 = @value", sqlConnection) sqlCommand.Parameters.AddWithValue("@value", "myValue") This code adds a parameter @value to the query and sets its value to "myValue" . Imports System
