How To Trigger The Update Command Of The SQLDataSource
Jun 13, 2006
Hi - I'm using .net2, and have a gridview, populated by a SQL Datasource (Edit, Insert, Delete, Select).
Like we all used to do with the datagrid, I've added text boxes into the footer, and a link button, which I'd like to use to fire the Update command.
How do I get the link button to trigger the update command?
Thanks, Mark

Is there any way I can use a variable from my code behind file in the UpdateCommand of a sqlDataSource? I have tried
<%$ strUserGuid %>and<% strUserGuid %>

I have a gridview with a sqlDataSource with the SelectCommand as
"SELECT Movie.Title, Movie.Category, Movie.ReleaseDate, ItemForSale.Quantity, ItemForSale.HasUnLimitedQuantity FROM ItemForSale INNER JOIN Movie ON ItemForSale.ID = Movie.ID"
what kinda 'UpdateCommand' do I set so that ItemForSale is also updated from the grid? I tried two update statements seperated with a semicolon but that wouldn't work, any suggestions...

Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">
<UpdateParameters>
<asp:ControlParameter Name="USERNAME" ControlId="txtUserName" PropertyName="Text"/>
<asp:ControlParameter Name="SERVICE_TAG" ControlId="txtServiceTag" PropertyName="Text"/>
<asp:ControlParameter Name="TECH" ControlId="txtTech" PropertyName="Text"/>
<asp:ControlParameter Name="DESKTOP" ControlId="txtComputerName" PropertyName="Text"/>
</UpdateParameters>
</asp:SqlDataSource>

Hi
I've created this simple trigger that will insert records into another table when an insert has occurred on another.
table A
table B
CREATE TRIGGER [TG_MYTRIGGER]
ON [dbo].[A]
AFTER INSERT
AS
Begin
INSERT B (date, id)
Select DISTINCT i.date,i.id
from inserted i
End
What i cant figure out is how to insert the date plus one month into table B
so instead of just inserting into the second table the i.date i want the i.date + one month.
Does anyone know how this could be done.
many thanks
Bil

I am using <asp:SqlDataSource ID and for the Select Command, the following, where the WHERE clause ... for an exact match (=) works correctly:
SelectCommand="SELECT [PatientID], [MedRecord] , [Accession], [FirstName], [LastName], [Address1] FROM [ClinicalPatient] WHERE (LastName = @LastName) ORDER BY [LastName]DESC">
I would like to do a "LIKE" search where the LastName Parameter is matched using "LIKE". In this situation how would the syntax be written.... I tried:
LastName LIKE '%" & LastName & "%'"
But I get an error???? Any suggestions, please...
Thanks !!

Hello all,
I am having problem to insert the record into database from sqldatasource control. my code is listed below, and i can't find anything why it cause the exception...
<asp:SqlDataSource ID="SqlDataSource1" runat="server" DataSourceMode="DataSet" ConnectionString="<%$ ConnectionStrings:WebsiteDataConnection %>" SelectCommand="SELECT * FROM [ServiceAgents]" InsertCommand="INSERT INTO ServiceAgents VALUES(@Ser_STATE, @Ser_CITY, @Ser_AGENT, @Ser_PHONE, @Ser_EQUIPMENT)"> <InsertParameters> <asp:FormParameter Name="Ser_STATE" FormField="TextBox_state"/> <asp:FormParameter Name="Ser_CITY" FormField="TextBox_city"/> <asp:FormParameter Name="Ser_AGENT" FormField="TextBox_agent"/> <asp:FormParameter Name="Ser_PHONE" FormField="TextBox_phone"/> <asp:FormParameter Name="Ser_EQUIPMENT" FormField="TextBox_equip" /> </InsertParameters> </asp:SqlDataSource>
The table has got the fields that needed for insert command, for example:
<table> <tr> <td>State:</td> <td> <asp:TextBox ID="TextBox_state" runat="server"></asp:TextBox> <asp:RequiredFieldValidator id="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox_state" Display="Static" ErrorMessage="Please enter a state." /> </td> </tr> <tr> <td>City:</td> <td> <asp:TextBox ID="TextBox_city" runat="server"></asp:TextBox> <asp:RequiredFieldValidator id="RequiredFieldValidator2" runat="server" ControlToValidate="TextBox_city" Display="Static" ErrorMessage="Please enter a city." /> </td> </tr> <tr> <td>Agent:</td> <td> <asp:TextBox ID="TextBox_agent" runat="server"></asp:TextBox> <asp:RequiredFieldValidator id="RequiredFieldValidator3" runat="server" ControlToValidate="TextBox_agent" Display="Static" ErrorMessage="Please enter a agent." /> </td> </tr> <tr> <td>Phone:</td> <td> <asp:TextBox ID="TextBox_phone" runat="server"></asp:TextBox> <asp:RequiredFieldValidator id="RequiredFieldValidator4" runat="server" ControlToValidate="TextBox_phone" Display="Static" ErrorMessage="Please enter a phone No." /> </td> </tr> <tr> <td>Equipment:</td> <td> <asp:TextBox ID="TextBox_equip" runat="server"></asp:TextBox> <asp:RequiredFieldValidator id="RequiredFieldValidator5" runat="server" ControlToValidate="TextBox_equip" Display="Static" ErrorMessage="Please enter a equipment." /> </td> </tr> <tr> <td></td> <td> <asp:Button ID="Button2" runat="server" Text="Add" OnClick="addEntry" BackColor="#FFFBFF" BorderColor="#CCCCCC" BorderStyle="Solid" BorderWidth="1px" Font-Names="Verdana" Font-Size="1.0em" ForeColor="#284775"/> </td> </tr> </table>
And in the code i just called: SqlDataSource1.Insert(); Then the page gives me the exception like:
Cannot insert the value NULL into column 'STATE', table 'WebsiteData.dbo.ServiceAgents'; column does not allow nulls. INSERT fails. The statement has been terminated.
But i actually input all the required text in the textbox.... Any idea guys?
Thanks

I have a SqlDataSource object that is bound to a GridView control. I have configured the SqlDataSource with a default select command. Under certain values of query strings on the URL for this page (Default.aspx), I want to change the select command. So I put the statements in the Page_Load method for Default.aspx to define SqlDataSource1.SelectCommand. The changed SelectCommand works fine for the first page of GridView data and shows 5 GridView pages, but if I switch to one of the other pages, it seems to revert to the default SelectCommand (which generates 19 GridView pages). I assume I should put my code to change the SelectCommand somewhere else. Can someone help me with where to put it? Thanks!

i need to dyanamically generate my SQL commands so to do that i am generating sqldatasource commands programmatically rather declaratively. SELECT commands seems to work fine but DELETE isnt doing anything, here is my code:
SqlDataSource sdsConsultant = new SqlDataSource();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
loadDataSet(); //it just loads dataset used by formview
initializeSDS();
}
}
protected void initializeSDS()
{
string strConnection = ConfigurationManager.ConnectionStrings["myDB"].ToString();
sdsConsultant.ConnectionString = strConnection;
//SELECT
sdsConsultant.SelectCommand = "SELECT * FROM Consultants WHERE (id=@id)";
QueryStringParameter id = new QueryStringParameter("id", "id");
sdsConsultant.SelectParameters.Add(id);
//DELETE
sdsConsultant.DeleteCommand = "DELETE * FROM Consultants WHERE (id=@id2)";
QueryStringParameter id2 = new QueryStringParameter("id2", "id");
sdsConsultant.DeleteParameters.Add(id2);
//UPDATE
Page.Controls.Add(sdsConsultant);
FormView1.DataSource = sdsConsultant;
FormView1.DataBind();
}
my formview control looks like:
<asp:FormView DefaultMode="Edit" ID="FormView1" runat="server" DataKeyNames="id"
OnItemDeleted="FormView1_ItemDeleted"
OnItemDeleting="FormView1_ItemDeleting">
the DELETE doesnt execute and the OnItemDeleted event doesnt do anything either. am i doing something wrong here? plz help

I have a GridView (that uses SqlDataSource1) and a Dropdownlist. Depending upon the value selected on the DropDownList I need to select different stored procedures for the gridview. The problem is that I can do it without taking SqlDataSource1 by using DataSet or DataTable. But, I need to Use SQLDataSource1 for easy way of Header SORTING. So, is there any way to change the SQLDatasource1.SELECT Command dynamically. So that, I can use different queries for the Single DataGrid. I have attached the sample code of the SqlDataSource1 I'm using. I need to change the Command i.e. SelectCommand="usp_reports_shortages" to "usp_reports_shortagesbyID" and "usp_reports_shortagesbyDate" depending on the value selected in the dropdownlist. So, is there any way to do this????<asp:SqlDataSource ID="SqlDataSource1"
runat="server"
ConnectionString="<%$
ConnectionStrings:TESTDrivercommunication %>"
SelectCommand="usp_reports_shortages" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ControlParameter ControlID="lblDriver" Name="date1" PropertyName="Text" Type="DateTime" />
<asp:ControlParameter ControlID="lblTODate" Name="date2" PropertyName="Text" Type="DateTime" />
<asp:ControlParameter ControlID="DDlDriver" Name="driver" PropertyName="SelectedValue"
Type="Int32" />
<asp:SessionParameter Name="week" SessionField="s_week" Type="DateTime" />
</SelectParameters>

I have an SQLDataSource. The SQL is
SELECT UserName, Category, ItemDescription, Size, Price, Reduce, Donate, Sold, ItemNumber, SoldDate, SoldPrice, PrintedFROM Tags WHERE (Printed = @Printed1 OR Printed = @Printed2 OR Printed = @Printed3) ORDER BY ItemNumber DESCThe bit field "printed" can be NULL, True or False.In the Selecting event of the SQLDataSource I have the following to show ALL records. But it does not work. If I remove these parameters it show ALL records.
e.Command.Parameters("@Printed1").Value = Nothing 'ASP.NET 2.0 using Visual basice.Command.Parameters("@Printed2").Value = Truee.Command.Parameters("@Printed3").Value = False

I apologise if i have not posted this in the correct Topic before i start. But was uncertain where to post this query.
This is my first project in ASP.NET, MS Visual Web Developer 2005 Express and SQL Server 2005 Express. I have relatively little experience, so please bare with me.
I have managed to create a form that inserts data into a table and then inserts the Automatically Created Primary Key(as a foreign key) in another table. I have done this by inserting what is highlighted in red in the code of my InsertCommand below (Please scroll across to the end of the code):-InsertCommand="INSERT INTO [PrinterModel] ([Model], [PrinterMakeID], [CartridgeCode], [PartCode], [Duplex], [NIC], [Wireless], [Parallel], [USB], [Colour], [PrinterTypeID]) VALUES (@Model, @PrinterMakeID, @CartridgeCode, @PartCode, @Duplex, @NIC, @Wireless, @Parallel, @USB, @Colour, @PrinterTypeID) INSERT INTO [Model] ([PrinterModelID],[TypeID]) VALUES (@@IDENTITY, 3)" Can you see any problems that may arise from using this method. This project is an Asset Management System and will be used by no more than a handful of users. My Concern is the use of the @@IDENTITY (As it only stores the last Key used). Should I be using it here? If there is more than one user inserting into tables (Chances of this happening are very low), will the correct Primary key be insert to the table in the above code?Thank you for your comments.

I am trying to implement an "advanced search" feature on my ASP.NET 2.0 web form. I have a GridView control and a SqlDataSource. The SqlDataSource control successfully retrieves data when the SelectCommand attribute is set in the aspx page. I need to make it so when a user clicks on a button, it can take a value from a text box and use it in the WHERE clause. I have tried setting the SelectCommand programmatically and then DataBinding but it never accepts the new SelectCommand. What can I do to fix this?

Hello all,I'm writing a site with one page that uses the session variable (User ID) to pick one user ID out of a comma separated list in the field Faculty. The default parameterized query designed in the SqlDataSource wizard only returns lines that contain an exact match:SELECT * FROM tStudents WHERE ([faculty] = @faculty) The query: SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') works as I need when I hard code the query with a specific user ID into the SqlDataSource in the aspx page. It will not work if I leave the @faculty parameter in it:SELECT * FROM tStudents WHERE ([faculty] LIKE '%@faculty%') e.Command.Parameters works to replace the @Faculty with a user ID, but again, adding the single quote and percentage sign either causes errors or returns no results. I've tried several variations of: string strEraiderID = "'%" + Session["eRaiderID"].ToString() + "%'"; e.Command.Parameters["@faculty"].Value = strEraiderID;no results are returned, not even the lines returned with the default select query.How do generate the equivalent of SELECT * FROM tStudents WHERE ([faculty] LIKE '%userID%') into the SqlDataSource? Thanks much!

Hi,
Hope you guys won't mind this rather newbie question. I'm writing a simple blog page for my website and have created a SqlDataSource which queries the database for a list of blog post titles (from the web.Blog table) and the number of comments (from the web.BlogComments table). The SqlDataSource control is:
<asp:SqlDataSource ID="sourceBlogArticles" ProviderName="System.Data.SqlClient" connectionString="<%$ ConnectionStrings:myDatabase %>" runat="server" SelectCommand="SELECT gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded, COUNT(gbc.blogID) AS noOfComments FROM web.Blog gb LEFT OUTER JOIN web.BlogComments gbc ON gb.blogID = gbc.blogID GROUP BY gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded ORDER BY gb.dateAdded"></asp:SqlDataSource>
This works perfectly well if each blog entry in the web.Blog table has associated comments in the web.BlogComments table. However, if there are no comments yet defined in the web.BlogComments table for that blogID then no row is returned in ASP.Net (as checked with a GridView control or similar linked to the data source to view what I get)
HOWEVER, I think the SELECT command IS correct: if I use the select command as a query in SQL Server Managment Studio Express, I do get the rows returned, with 0 for the number of comments which is what I would expect for that query:
blogID, title, description, tags, dateAdded, noOfComments
1, title 1, description for title 1, tag1, 2007-09-27 06:49:03.810, 32, title 2, description for title 2, tag2, 2007-09-27 06:49:37.513, 03, title 3, description for title3, tag3, 2007-10-02 18:21:30.467, 0
Can anyone help? The result from the SSMSE query is what I want, yet when I use the very same SELECT statement in my SqlDataSource I don't get any rows returned if the BlogComment count is zero (in the above example I get only the first row). Many thanks for any suggestions!

hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

Hi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,

I'm new to ASP and ASP.NET so I used the Wizards in Visual Web Deverlopment Express 2005 to build the following code:<asp:DetailsView ID="DetailsView" runat="server" DataSourceID="TracksDataSource"
Height="50px" Width="125px" AutoGenerateEditButton="True" AutoGenerateRows="False">
<Fields>
<asp:BoundField DataField="pk_trackID" HeaderText="pk_trackID" ReadOnly="True" SortExpression="pk_trackID" />
<asp:BoundField DataField="trackName" HeaderText="trackName" SortExpression="trackName" />
<asp:BoundField DataField="trackPath" HeaderText="trackPath" SortExpression="trackPath" />
<asp:BoundField DataField="lyrics" HeaderText="lyrics" SortExpression="lyrics" />
</Fields>
</asp:DetailsView>
<asp:SqlDataSource ID="TracksDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:connectionString %>"
SelectCommand="SELECT * FROM [Tracks] WHERE ([pk_trackID] = @pk_trackID)" UpdateCommand="UPDATE [Tracks] SET [trackName] = @trackName, [trackPath] = @trackPath, [lyrics] = @lyrics WHERE [pk_trackID] = @pk_trackID" >
<UpdateParameters>
<asp:Parameter Name="trackName" Type="String" />
<asp:Parameter Name="trackPath" Type="String" />
<asp:Parameter Name="lyrics" Type="String" />
<asp:Parameter Name="pk_trackID" Type="String" />
</UpdateParameters>
<SelectParameters>
<asp:ControlParameter ControlID="TracksListBox" Name="pk_trackID" PropertyName="SelectedValue" Type="String" />
</SelectParameters>
</asp:SqlDataSource> However, when I click Edit, change something, and then Update it doesn't update the database. However, if I remove the DataField bindings and use the AutoGenerateRows feature it works fine.

One of the requirements of the UpdateParameters for a GridView I'm building is that the fields that are being edited via EditItemTemplates are passed back to the UpdateParameter as XML. How would I go about combining the fields from the GridView/EditItems into an XML string that I can set as an asp:Parameter?
Thanks.
