know if the followin is supported in .net framework 4.0?I have a sql stored procedure with one of its parameter as Hierarchy data type( i suppose its a table valued parameter).. trying to drag this stored procedure onto my linq design studio is not being allowed?
View 1 RepliesI'm trying to figure out if it's possible to use an ObjectDataSource Update method with a table-valued parameter. Here's my ODS:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
DataObjectTypeName="TestProject.MyTestDataTable"
SelectMethod="GetTestData" TypeName="TestProject.BLL.TestBLL"
OldValuesParameterFormatString="original_{0}"
UpdateMethod="UpdateTestData">
<SelectParameters>
<asp:Parameter DefaultValue="65" Name="testId" Type="Int32" />
</SelectParameters>
</asp:ObjectDataSource>
I bind this to a GridView but I'm not looking to edit row by row. Instead my GridView has a bunch of TemplateFields with textboxes. I also have a Button that when pressed, invokes the Update method of the ODS. So then the "UpdateTestData" function in my TestBLL is called. This looks like this:
public void UpdateTestData(MyTestDataTable dt)
{
QueriesTableAdapter qta = new QueriesTableAdapter();
qta.UpdateTestData(dt);
}
At run-time in debug, it seems like the object for the signature above is not populated with the data from my GridView.
I have a requirement whereby my users need to be able to select the options in the 'departments' dropdown list (multi-valued parameter) of the report based on his designation. For instance, normal users should only see his own department while the administrator could see all the departments in the organization etc...The departments that the users could select are already retrieved in my code (asp.net). Now I need to know how to pass those values over to the reportviewer to populate the departments dropdown list in there. Any idea how to come about doing that?

using (Entities db = new Entities())
{
LoadDropDownList(ddlFirst, db.MyTable , (bool)(myMember.Id == 0), (int)myMember.RevenueRangeID);
LoadDropDownList(ddlSecond, db.OtherTable , (bool)(myMember.Id == 0), (int)myMember.OtherID);
}
I am stumbling on what the type of the second parameter should be - I am essentially trying to pass in the Entity-Framework 'table' into a generic routine that loads the DropDownList with data from the 'MyTable' table using custom logic/filtering.SInce I do the same thing about 6 times for 6 different dropdownlist/table combos I wanted to use a generic function to accomplish this.
If an ASP.NET web page uses an ObjectDataSource, can you configure it to use a stored procedure that uses table-value parameters?
User-defined type:
CREATE TYPE [dbo].[integer_list_tbltype] AS TABLE
(
[n] [int] NOT NULL,
PRIMARY KEY CLUSTERED
)
Stored procedure:
CREATE PROCEDURE [dbo].[GeneralReport]
@intList integer_list_tbltype READONLY
AS
BEGIN
SELECT * FROM ...
END
ASP.NET
<asp:ObjectDataSource ID="GeneralDataSource" runat="server"
SelectMethod="GetDataByRange"
TypeName="MyProject.GeneralDataSetTableAdapters.GeneralViewTableAdapter"
>
<SelectParameters>
<asp:Parameter Name="intList" />
</SelectParameters>
</asp:ObjectDataSource>
I've tried hooking into the ObjectDataSource's Selecting event like this:
[code]....
be set for UDT parameters." being thrown
This is my first attempt in using table valued parameters in my stored procedures. Please find the scripts down below. The idea is very simple. I'm trying to insert a new product into Products table and if the product has attributes, I'll insert them into ProductAttributes table which is where I use table-values parameters.
I was able to test the stored procedure manually. It's working fine. So the error must be in the C# code but there's not much to it.
Here's the DAL code in C# that calls the stored procedure:
[Code]....
Just in case you need it, here's what my Product object looks like:
[Code]....
And the ProductAttribute object is even simpler:
[Code]....
Here's the SQL scripts to create the tables, stored procedure and user defined table type:

I would like to know which one is better, table-valued function or View, in terms of perfomance.Earlier I have created view which is performing cross join (which takes time) and 2/3 Left outer join and it's taking time. To reduce execution time I have created table-valued function with parameter to reduce cross join execution time and it returns the same result as view.Just give me an idea about table-valued function and View, in terms of perfomance. Which one is better?
View 1 RepliesWhats the best method to use with MVC? Entity Framework or LINQ to SQL?
View 4 RepliesIm working on a greenfield project and have to make a decision on the technology we'll use for the data access layer. Ive used LINQ to SQL for a few years and am happy and comfortable with this, but now with entity framework available this is another method to consider. Are there any pitfalls using entity framework as opposed to LINQ to SQL ? Ive read that there are performance issues with entity framework, is this true? Id really like to get an overall feel for using one method over the other, anyone have any thoughts/comments/recomendations?

View 1 Repliesi have 2 table missions and missiondays with a relationship 1..n
I want select all missions that has all missiondays with an attribute called "visible" = true
I've tried with:
db.TDP_Missioni.Include("TDP_MissioniDestinazioni").where(p => p.TDP_MissioniDestinazioni.visible == true)
But there is an error. Indeed from p.TDP_MissioniDestinazioni i don't see the table's attributes. I think it's because the relationship is 1..n.
