    <p>Here is my stored procedure that does the update and when I test the procedure using SQL Server it works perfectly.</p> <pre><code>ALTER PROCEDURE [TKSFlex].[UpdateComment] -- Add the parameters for the stored procedure here @Comment char(50), @Employee char(25) AS BEGIN TRANSACTION -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT On; -- Insert statements for procedure here Update whiteboard set Comment = @Comment where Employee = @Employee COMMIT </code></pre> <p>And here is the code executed when the update button is clicked</p> <pre><code>Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal es System.EventArgs) Handles btnUpdate.Click InputsModule.Employee = "'Mathe BF'" Objconn.Open() dbcommand.Connection = Objconn dbcommand.CommandType = CommandType.StoredProcedure dbcommand.CommandText = "[TKSFlex].[UpdateComment]" dbcommand.Parameters.AddWithValue("@Comment", txtComment.Text) dbcommand.Parameters.AddWithValue("@Employee", InputsModule.Employee) 'dbcommand.Parameters.Add("@Comment", SqlDbType.Char).Value = txtComment.Text 'dbcommand.Parameters.Add("@Employee", SqlDbType.Char).Value = InputsModule.Employee Dim i As Integer = 0 Try i = dbcommand.ExecuteNonQuery() Catch ex As SqlException MsgBox("failed") End Try Objconn.Close() End Sub </code></pre> <p>By the table doesn't get updated when the query is executed and an Exception doesn't get thrown, which implies the the code does get executed but no modification is made to the database, I'm just not sure where I went wrong</p>

    1. COYou need to define **a length** for any character parameters - e.g. use this: `dbcommand.Parameters.Add("@Comment", SqlDbType.Char, 50).Value = txtComment.Text` - otherwise, your parameter is **just one character long**!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
