User Defined Functions in Microsoft SQL Server

User Defined Functions are compact pieces of Transact SQL code, which can accept parameters, and return either a value, or a table. They are saved as individual work units, and are created using standard SQL commands. Data transformation and reference value retrieval are common uses for functions. LEFT, the built in function for getting the left part of a string, and GETDATE, used for obtaining the current date and time, are two examples of function use. User Defined Functions enable the developer or DBA to create functions of their own, and save them inside SQL Server.

Use a column as parameter for a sds in another column; gridview


Hola, I have a gridview which is bound to a sds which returns 7 columns and I added two columns from the GUI.  What I want is to fill up the 9th column with DDLs and these  DDLS will get their data from a different sds which is using a stored procedure with a single parameter.  I created the 9th row, used template field, made the sds for 9th row, the stored_procedure, threw a DDL in Item template and all  I need now is to pass a parameter in the first column to the sds in the 9th column.  I can code this but i'm getting tired of aspx.cs :) and would like to do it from the GUI.

Sort by gridview SortExpression parameter via Stored Procedure


I have a gridview that calls data via a stored procedure.  I am unable to enable the gridview columns to be sortable. I need to set the parameter in the Stored Procedure, can someone help me with this?

Here is my gridview:

<asp:GridView ID="AllUsersGrid" runat="server" AutoGenerateColumns="False" DataKeyNames="UserName"
                        GridLines="Vertical" Width="900px" DataSourceID="SqlDataSource1" AllowSorting="True"
                        SelectedRowStyle-Height="30px" CellPadding="4" BackColor="White">
                            <asp:TemplateField HeaderText="Full Name" SortExpression="lastname">
                                    <asp:Label ID="DisplayName" runat="server" Text='<%# Eval("firstname").ToString() & " " & Eval("lastname").ToString() %>' />

This is frustrating, and I don't know how to solve it.

I have a strange problem. I am adding a LinqDatasource object, and set the context:

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

Then I get this error:
The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


On web.config I already have this:
<add assembly="System.Data.Linq, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?


type object parameter



I have a problem I can't figure out.

I've been trying to add a listbox with multi select enabled as a parameter to my select statement in sqldatasource.

So i created a function like this :

string strItemTypes = "";
foreach (ListItem li in lbItemType.Items)
   if (li.Selected)
      strItemTypes += "," + li.Value;
strItemTypes = strItemTypes.Substring(1);

which gives me the selected items like this for example : "1,2,3"...
Then I've been trying to add it to my sql select statement :

SELECT tblOfficesItems.idOfficesItems, tblStockItems.Name, tblStockItems.Description, tblStockItemTypes.TypeItem, tblStockItems.Notes FROM tblOfficesItems INNER JOIN tblStockItems ON tblOfficesItems.fkItem = tblStockItems.idItem INNER JOIN tblStockItemTypes ON tblStockItems.fkTypeItem = tblStockItemTypes.idTypeItem WHERE tblStockItems.fkTypeItem IN ( @fkTypeItems )

using a hiddenfield with a controlparameter of type=object
but it just don't seem to work, seems like the data just won't bind or something and I don't get any errors so I'm confused!!

then i tried this :

SELECT tblOfficesItems.idOfficesItems, tblStockItems.Name

Composite Control which contains arbitrary content defined in .aspx of parent and thier ViewState


I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control. But now I have issue with ViewState of inner controls of my control. The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside. When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?

"Type ASP.x is not defined" error for dynamic user control when publishing updateable


I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

asp expression bound to user control parameter?


How can I get pass the DataKey of a GridView to a usercontol, preferably without code behind.

Why doesn't this work:

<ucOrderDetails:AJAX_OrderDetail ID="od1" runat="server" OrderNumber='<%# GridView1.SelectedValue.ToString() %>'  />

GridView1 is just a list of orders with a DataKey of OrderNumber.

od1 is not inside of a databout control, does it need to be?
