Dear All:
I want to ask how can I handle OnError events in stored procedure in MSSQL.
Actually I wanted to place some Rollback procedure on this.
Can you suggest some methods for me?

I've posted a few questions on what we dba's let the developers do in a production database and the consensus seems to be not to let them issue DDL cmds e.g. create table, views ... This brings me to this question on how do you handle the developers requests for changes in a production database. If anyone is willing to post their requirements I'd really appreciate it. I'm thinking about a master excel sheet on that would contain fields for the request but I want to make sure I'm getting everything that I need.
Thanks in Advance
Hello,
Please, help with following issues.
I have 3 parameters in the report. When user selects 1st one from dataset, one of the fields gives me object creation date. Calendar control is supposed to be filtered to allow users select the dates greater than selected one.
How can I filter (disable dates in) calendar control?
Any suggestion/comment highly appreciated
Hi All,
I need to send out email when error occurs in the package. Is it a good practice to put the send email task in the event handler? Then MaximumErrorCount is set to 1. But for some reason, some time I saw more than one email are sent out. Please advise. Thanks
Hi All,
I have following:
a text input for filtering
a gridview that displays the data
an SqlDataSource that contains the query.
Users can either enter something into the text input or leave it blank. Depending on that, the gridview should either display all data (unfiltered, because nothing was entered into the text field) or filtered data (when something is entered).
Now my problem is in defining the query in the SqlDataSource. I could do something like this:
SELECT * FROM myTable WHERE myField = @p1;
and then add in the appropriate <asp:ControlParameter /> under the <SelectParameters> tag. However, this sorta "fixes" the filter. Regardless of whether users actually type something in or not, the filter is in effect. I want it in such a way that if users do not type in anything, the query essentially becomes:
SELECT * FROM myTable;
Is there any way to achieve this?
Thanks in advance,
jason
I think I might be missing something here.
Here is what I'd like to do:1. Retrieve a list of data from SQL Server.2. Display that data in a gridview.3. Have the user click on a button to then see a subset of that data. (filtering)
I can't seem to make this work. When the user clicks the button, I need the GridView to update to show only the specified data. In 1.1 I would created a DataView for the filtering, but am trying to use the latest and greatest.
I've seen examples online of people using DropDownLists to act as the dynamic filter parameter. How can I programatically assign this to make it work?Thanks!
Greetings,
I have a question about the best method to ensure the proper flow of control within a package. I have three related SQL tasks €“ A, B, and C €“ that must execute in sequence. If any one of the tasks fails then the remaining tasks should not execute because each is dependent on the previous step. (A €œsuccess€? precendence constraint.)
Likewise, I have a second set of SQL tasks €“ 1, 2, and 3 €“ that must execute in sequence. Task 3 should never execute unless tasks 1 and 2 have been successful.
I consider these to be two independent logic paths in the same package and, indeed, when I run the package both task A and task 1 begin running at the same time.
What I€™m not sure of is how to add a new task €“ Z €“ that will execute only after both the A-B-C and 1-2-3 task paths have completed. Diagramatically, this would be like having a €œcompletion€? constraint linking task C to task Z and another €œcompletion €œ constraint linking task 3 to task Z. In other words, the two independent paths merge at task Z. Task Z is an audit step that must always run €“ it emails summaries of the database activities performed by the other tasks.
What has me puzzled is how I get to Z when there is a failure in either the A-B-C path or the 1-2-3 path. As things stand now, the package will never reach task Z if there is a failure in an earlier task because they are joined by a €œsuccess€? constraint.
I thought I could get around this by using a €œsequence container€? but I discovered when I added A, B, and C to a container that I couldn€™t use the €œsuccess€? constraint I needed. I was just guessing that this might be the way to do it.
Can anyone help me with a best practice approach to the control flow issue I face? I€™m new if that isn€™t apparent by my question, so don€™t be afraid to make your answer simple and plain.
Thanks for any help,

View 1 Replies View RelatedHi -- I'm starting an ASP.NET 2.0 application which contains a page with a checkbox and gridview control on it. In its default state the gridview displays all the records from a table pulled from a SQL Server database (via a SqlDataSource object). When the user checks the checkbox, I want the gridview to display only the records where one of the columns is not null. But I've been unable to construct the WHERE clause of the SQLDataSource object correctly. I see that I can hard-code the SqlDataSource object so that the column to be filtered is always NULL or always NOT NULL. But I want this filtering to be more dynamic such that the decision to show all or non-null records happens at run-time. Should I be using two SqlDataSource objects -- one for the NOT NULL condition and one for the "all records" condition? Then when the user checks the checkbox, the gridview would be configured to point to the appropriate SqlDataSource object. (???) Seems like a bit of overhead with that approach. I'm hoping there's a more elegant way to get this done. Please let me know if you need more information. Thanks in advance. Bill

I have two SQLDataSource controls on my page that are dynamically fed an SQL SELECT statement. I was thinking that the best way to do this was to give it the select statement that it needs inside the OnSelecting event. Here is the revelent code.
<asp:SqlDataSource OnSelecting="GetData_Selecting" ID="DS1" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" ProviderName="<%$ ConnectionStrings:MyConnectionString.ProviderName %>" runat="server" SelectCommand="" />
<asp:SqlDataSource OnSelecting="GetData_Selecting" ID="DS2" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" ProviderName="<%$ ConnectionStrings:MyConnectionString.ProviderName %>" runat="server" SelectCommand="" />
protected void GetData_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
System.Diagnostics.Debug.WriteLine("Getting Data...");
switch ((sender as SqlDataSource).ID)
{
case "DS1":
if (Checkbox1.Checked)
{
e.Command.CommandText = "SELECT * FROM table1 WHERE " + BuildQuery(getMylarColumns(), SearchBox.Text);
DS1Panel.Visible = true;
}
break;
case "DS2":
if (Checkbox2.Checked)
{
e.Command.CommandText = "SELECT * FROM table2 WHERE " + BuildQuery(getFlatFileColumns(), SearchBox.Text);
DS2Panel.Visible = true;
}
break;
}
The problem with this is that the GetData_Selecting method is never executed and thus when I try to execute the query the page PostBacks and nothing happens. Putting equivalent code in the Page_Load method works fine, however I believe having the code execute on each PostBack is the reason I'm having another problem sorting the data in the DataGrids these controls are bound to.
Why is the function never being executed? Is this the ideal way to handle the inclusion of the query in the SQLDataSource?
Hello,
on my site I have a sqldataSource and a listview working together. But now after selecting data from my database and before binding data to the listview i want to change the data. For example: I select an image filename and i want to check if the file exists, and if it not exists i want to change this filename. How can I do that. My Idea was to use the OnSelected Event of the datasource, but i don't know how to acces the selected data ...
I hope someone can help me

Greetings,
When using Inserting event of SqlDataSource ASP.NET gives me an error when I reference InsertParameter by Name
An SqlParameter with ParameterName 'CreatedByEmployeeId' is not contained by this SqlParameterCollection.
However, when I reference parameter by index everything works.
Is this a bug or I'm doing something wrong?
Here's the code:
<asp:SqlDataSource ID="dsRole" runat="server" ConnectionString="<%$ ConnectionStrings:SecurityConnectionString %>" DeleteCommand="spDeleteRole" InsertCommand="spAddRole" SelectCommand="spGetRole" UpdateCommand="spUpdateRole" DeleteCommandType="StoredProcedure" InsertCommandType="StoredProcedure" SelectCommandType="StoredProcedure" UpdateCommandType="StoredProcedure">
<DeleteParameters>
<asp:Parameter Name="RoleId" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="RoleId" Type="Int32" />
<asp:Parameter Name="RoleName" Type="String" />
<asp:Parameter Name="RoleDescription" Type="String" />
<asp:Parameter Name="UpdatedByEmployeeId" Type="Int32" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="RoleName" Type="String" />
<asp:Parameter Name="RoleDescription" Type="String" />
<asp:Parameter Name="CreatedByEmployeeId" Type="Int32" />
</InsertParameters>
<SelectParameters>
<asp:ControlParameter ControlID="GridView1" Name="RoleId" PropertyName="SelectedValue" />
</SelectParameters>
</asp:SqlDataSource>
When using parameter name, I get an error:

e.Command.Parameters("CreatedByEmployeeId").Value = Internal.Security.GetEmployeeIdFromCookie(Page.Request.Cookies)
End Sub
When using index instead of name, there's no problem:
Protected Sub dsRole_Inserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles dsRole.Inserting
e.Command.Parameters(2).Value = Internal.Security.GetEmployeeIdFromCookie(Page.Request.Cookies)

Hi
In the page load of my webpage I call a databind for a gridview.
It generally calls this event handler :
protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
However sometimes (seemingly randomly) it doesn't.
Any ideas?
Thanks
p
protected void Page_Load(object sender, EventArgs e)
{
...
if (searchText != "")
SqlDataSource1.SelectParameters["search"].DefaultValue = searchText;
else{
SqlDataSource1.SelectParameters["search"].DefaultValue = "";
GridView1.DataBind();
}
Hi All - I've got a simple gridview/sqldatasource page, but the sqldatasource_onSelected event isn't firing.
heres the parameters <SelectParameters>
<asp:QueryStringParameter Name="LicenceID" QueryStringField="LicenceID" Type="string" />
<asp:QueryStringParameter Name="SiteID" QueryStringField="SamplingSiteID" Type="string" />
</SelectParameters>
either or both parameters may be null (ie. not in querystring ) .
If only one of the selectparameters is null, and I remove it, the event fires!!!
The parameters in the stored proc are optional(ie. default = NULL) and it works fine if I test it in SQL .
Whats going on? If there's some error happening, why no error raised? if there are no records returned, the onselected event should still fire shouldn't it?

Hi,
I have a SqlDataSource whose select statement uses parameters from the selected row on a gridview on the page. So when a row is selected in the gridview, I want the SqlDataSource to do a select using the new parameters, and then I want to inspect the number of rows returned. If 0, I want to set a FormView to insert mode, if >0 I want to set the FormView to edit mode.
The "SqlDataSource2_Selected" sub never fires, so I cannot retrieve the number of rows returned. How can I deal with this? I would like the SqlDataSource to execute a Select each time the Gridview selected row changes. What could prevent "OnSelected" from firing?
I do have "OnSelected="SqlDataSource2_Selected" within the SqlDataSource tag.
Thanks in advance for any help with this.
I have a gridview connected to a sqldatasource, and it works pretty good. It gives me the subsets of the information that I need. But, I really want to let them choose all the companies and/or any status. What's the best way to get all the values in the gridview...besides removing the filters :)

Do you have to use the sqldatasource in conjuction with another control like gridview or dropdown list?

Hello, I want to loop through the first 10 records that are showing in a gridview with several pages that is populated by a sqldatasource. I can loop through the sqldatasource and get the list of values, but I'm doing something wrong because the 10 records it prints out are not the same 10 records the user sees in the gridview...They can click a search button which changes the sort, and they can click on the column headings to change the sort order.

How do you set a timeout for an SqlDataSource control?
View 1 Replies View RelatedAnyone can help me ?
View 4 Replies View RelatedHello:
I am having a little issue with an error that is frustrating me. I have a SqlDataSource within an asp:label control and also have a two dropdownlists inside that asp:label control also. When I select from the first dropdownlist, it should enable the second dropdownlist with the populated data, but instead I receive.
The SqlDataSource control 'sqlGetMLSByCity' does not have a naming container. Ensure that the control is added to the page before calling DataBind.

Any help would be great, thank you!
I have an SqlDatSource that I have fully setup at design time, but I don't want it to open and load as soon as the page loads, instead I want to open it based on a condition.
How do you do that with a DataSource?
I know that I can simply remove the Select query, and then set it at run time, but I'm looking for something better, that allows me to have the Select query set at design time, in part because I have a lot of parameters.
