Here is my compilation of example code for a variety of database operations written in VB.NET These range from: Continue reading “VB.NET Basic Database Query Examples”
In the example functions below I’m illustrating how to set up a basic query to a stored procedure in your database that takes a single string parameter. The examples involve using the SQLDataAdapter object to Fill a DataSet. The resulting DataTable can then be queried as desired. Specifically:
- The first example shows how to read the first row of the results after your Datatable has been populated. I provide the same example in VB.NET and C#.
- The second example shows how to loop through the results if you anticipate multiple returned rows. As before, I provide the same example in VB.NET and C#.
As part of this code, remember to include the correct .NET Namespaces. If you are writing your code inline (in either VB.NET or C#), use:
<%@ Import Namespace="System.Data" %> <%@ Import Namespace="System.Data.SqlClient" %>
and if you are writing your code in codebehind, use:
Imports System.Data Imports System.Data.SqlClient
using System.Data; using System.Data.SqlClient;
