SQL Insert - How To Combine More Than One Field Value To A Single Column Insert
Jan 18, 2010
I have a form with many form fields and controls, with some offering an "other" if a value does not meet the needs for the user. How can I bind the sql insert so that it will take the ddl selection along with the txt field selection for the "other" value? Even if the txt field is empty it should not be a big deal since the ddl would provide something other than null. Since the column in the db does not allow nulls. I'm using asp.net (vb) 3.5 sp1
i use this to select one checkbox to isselected column how i convert this to multi checkboxlist to single column i use many ways more than 3 days without success
private void BindCheckBoxList() { DataTable dt = new DataTable(); SqlConnection connection = new SqlConnection(GetConnectionString()); try { connection.Open(); string sqlStatement = "SELECT * FROM boby"; SqlCommand sqlCmd = new SqlCommand(sqlStatement, connection); SqlDataAdapter sqlDa = new SqlDataAdapter(sqlCmd); sqlDa.Fill(dt); if (dt.Rows.Count > 0) { CheckBoxList1.RepeatColumns = 4; // set the number of columns in the CheckBoxList CheckBoxList1.DataSource = dt; CheckBoxList1.DataTextField = "Name"; // the items to be displayed in the list items CheckBoxList1.DataValueField = "Name"; // the id of the items displayed CheckBoxList1.DataBind(); //Setting the Selected Items in the ChecBoxList based from the value in the database //to do this, lets iterate to each items in the list for (int i = 0; i < dt.Rows.Count; i++) { if (!string.IsNullOrEmpty(dt.Rows[i]["IsSelected"].ToString())) { CheckBoxList1.Items[i].Selected = Convert.ToBoolean(dt.Rows[i]["IsSelected"]); } } } } catch (System.Data.SqlClient.SqlException ex) { string msg = "Fetch Error:"; msg += ex.Message; throw new Exception(msg); } finally { connection.Close(); } } private void Update(string name, bool isSelected) { SqlConnection connection = new SqlConnection(GetConnectionString()); SqlCommand cmd; string sqlStatement = string.Empty; try { connection.Open(); sqlStatement = "UPDATE handymen SET IsSelected = @IsSelected WHERE Name = @BizName"; cmd = new SqlCommand(sqlStatement, connection); cmd.Parameters.AddWithValue("@Name", name); cmd.Parameters.AddWithValue("@IsSelected", isSelected); cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); } catch (System.Data.SqlClient.SqlException ex) { string msg = "Insert/Update error"; msg += ex.Message; throw new Exception(msg); } finally { connection.Close(); } } protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { BindCheckBoxList(); } } protected void Button1_Click(object sender, EventArgs e) { string str = string.Empty; for (int i = 0; i < CheckBoxList1.Items.Count; i++) { if (CheckBoxList1.Items[i].Selected) { str = CheckBoxList1.Items[i].Text; Update(str, CheckBoxList1.Items[i].Selected); } } //ReBind the List to retain the selected items on postbacks BindCheckBoxList(); }

I am new to .NET and MVC, so this is most likely a simple question: How can I have a default value appear for an Html.TextBox or TextArea field, for example if the code is currently - <%=Html.TextBox("ApplyToFax", Model.Competition.ApplyToFax, New With {.class = "regular", .maxlength = "50"})%>. I am looking to have a default fax number appear in the box when the page loads, for example (999) 999-9999.
For example: INSERT INTO table (col1, col2, col3) VALUES ('value1','value2,'value3')But I would only like to insert the row if value3 isnt already present in col3 in some previous row.

I am trying to pass in as an insert parameter for SQLds2 the scope_identity of the insert of SQLds1.
Exception Details: System.InvalidOperationException: Error executing 'InsertCommand' in SqlDataSource 'SqlDataSource1'. Ensure the command accepts the following parameters: @Name1, @NewId
Getting the message that ObjectDataSource ... count not find a non-generic method ... that has parameters ... The parameter list is fine until I get to the very end and it list the two data fields that are in my DetailsView. Using the ASP Tutorial #17 (Examining the Events Associated with Inserting, Updating, and Deleting) and the Exploring the Data Modification - specifically the one showing the INSERT of the Product Name and UnitPrice. ASPX page is pretty simple and attempting something similar, two fields to insert a new record - update the other fields later.
Full Error Message follows along with ASPX and the AsignaturasBLL.cs. Interesting thing is that when I swap the two fields in the DetailView, then the last two fields in the error message are swapped. In the error message I bolded these two fields.
