DataSource Controls :: How To Write A Method That Uses SQLParameter To Insert Some Data Into SQL Server
Jun 30, 2010
I am about to write a method that uses SQLParameter to insert some data into SQL server. However, do I "have" to specify a DBType? If not how is this handled?
Protected Sub FormView1_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.FormViewUpdateEventArgs) Handles FormView1.ItemUpdating Dim IsPresCheck As CheckBox = CType(FormView1.FindControl("IsPrestigeChkBx"), CheckBox) If IsPresCheck.Checked = "True" Then SqlDataSource1.SelectParameters.Add("IsPrestige", System.TypeCode.Int32, 1.ToString) Else SqlDataSource1.SelectParameters.Add("IsPrestige", System.TypeCode.Int32, 0.ToString) End If
but for some reason it's not seeing the parameter and returning an error
i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
I have a <asp:Parameter Name="Person_ID" Type="String" />. My Updatecommand contains, among other things: Person_ID = @Person_ID. That's all fine.
In my code behind, how to I say that I don't want to specify a value for this parameter, but rather want it to use the default value (which in this case is NULL?)
Or rather than telling it to use the Default value, is it possible to set it to Null? I tried setting the value to Null, but the sql code that got generated was Person_ID = "NULL", which of course, is wrong. How do I get it to generate Person_ID=NULL?
I have an SQLSiteMapProvider that needs a unique URL and have not got the smarts to work out how to get the provider to do the work so for now I thought I would just add the data to the DB then edit the URL with the ID. I can't do this on the first insert as I do not know the ID as it is an auto generated Primary Key
I tried to us the PostBackURL to go to a 2nd Page that got the New ID and added it to the end of the already known URL "Page.aspx?ID=" but apparently you can't do that as I found out (This would have been a masive hack to the problem I know but it would have got around it issue of for now)
this is how I guessed it would work
Insert Data with URL "Page.aspx?ID=" and more data.... Then Get New ID and update URL to have the ID on the end ie: Page.aspx?ID=99
I am trying to follow this sample of inserting data through gridview rowcommand. But somehow Im missing the sqlparameter add method whilst the namespace was already added.
Code:
//sqlparameter declaration of list type private List<SqlParameter> insertParameters = new List<SqlParameter>(); mygridview_rowcommand(...){ SqlParameter _prm_guid = new SqlParameter("@pk_guid", SqlDbType.VarChar); _prm_guid.Direction = ParameterDirection.Input; _prm_guid.Value = thisguid; insertParameters.add(?); //error on add() }
Some other part of the code which related to insertParameters variable it give an error
Code: for statement cannot operate on variables of type List<System.Data.SqlClient.SqlParameter> because List<System.Data.SqlClient.SqlParameter> does not contain a public definition of GetEnumerator

I'm trying to execute a simple insert statement with the GUID and timestamp populated by default from the server. I have both of their default values set as (newid()) and (getutcdate()) respectively in SQL server. However, I receive the error when I try and execute the command "Insert Error: column name or number of supplied values does not match table definition". How do I construct my sql insert so my id and timestamp columns use their default values as assigned in sql server?
