View 4 RepliesI am having trouble with this I have 3 Data tables i use over and over again which are cached I would like to write a LINQ statement which would do the following is this possible?
T-SQL VERSION:
SELECT P.[CID],P.[AID]
,B.[AID], B.[Data], B.[Status], B.[Language]
FROM MY_TABLE_1 P
JOIN
(
SELECT A.[AID], A.[Data], A.[Status], A.[Language] FROM MY_TABLE_2 A
UNION ALL
SELECT B.[AID], B.[Data], B.[Status], B.[Language] FROM MY_TABLE_3 B
) B on P.[AID] = B.[AID]
WHERE B.[Language] = 'EN' OR B.[Language] = 'ANY' AND B.STATUS = 1 AND B.[Language] = 'EN' OR B.[Language] = 'ANY' AND B.STATUS = 1
Then i would like it to create a result set of the following
Results:
|CID|AID|DATA|STATUS|LANGUAGE
I have a DDL bound to a sqlDataSource, and I want to insert an item in the first position. I tried using this code in the onDatabound event:
Protected Sub ddl_onDataBound(ByVal sender As Object, ByVal e As EventArgs) Handles ddl.DataBound
ddl.Items.Insert(0, "None")
End Sub
But when I load the page, the item "None" is inserted twice at the beginning of the DDL? So I see something like:
None
None
item1
item2
Do I need to put the items.insert somewhere else, like on the pageLoad, to avoid it being executed twice, or am I doing something really wrong?
Edit and Delete functionality works flawlessly in Gridview if all data is pulled ONLY FROM ONE TABLE. But pulling data from one table give you ID's instead of actual values that are stored in other tables.
After creating a usable Select statement that would pull all the correct values, my Edit and Delete functionality no longer work.
Here is code.

I have a Winform that has fields need to be filled by a user. All the fields doesn't belong to one table, the data will go to Customer table and CustomerPhone table, so i decided to do multiple inserts. I will insert appropriate data to CustomerPhone first then Insert the rest data to Customer table.

I have a project that I was using Access for but now find I have to change to SQL Express. Well I have no big problem with that but I now find that the SQL Statement I have been using was for OLE and does not work in SQL/Express. I am not even sure anymore if I can dump the entire CSV file in at one time? The statement I was using is below.

Here is my problem. What is the INSERT statement to insert a complete flat (CSV) into SQL Express? OR what method can I use to preform this task?
I am doing a data warehouse project.I have two tables tblA (id, type) and tblB(city, no_crimes, type).I want to create (insert) a number of rows based on the value of no_crimes.For Example, in tblB(Leeds, 2000, murder). SO, I need to insert 2000 rows into tblA by a single INSERT statement (not 2000 statements).
View 3 RepliesIs this LINQ statment vulnerable to SQL injection?
var result = from b in context.tests
where b.id == inputTextBox.Text
select b;
where context is an Entity and tests is a table. I'm trying to learn LINQ and I thought that the benefit of it was that it wasn't vulnerable to sql injection, but some stuff I've see has said differently. Would I need to parametrize this LINQ statement to make it safer? If so, How? Also would this be considered linq to sql or linq to entities?

Is it possible to generate dynamic LINQ statements? I need to be able to build conditional "WHERE" clauses for some of my LINQ statements. I don't want to write a giant block of code to hand every possible combination of filters, sorts and groups. I found a article online that outlines how to use string based where clauses here. Does LINQ in framework 4.0 no longer support this? Every example I've found has giant walls of virtually unreadable, must likely unmaintainable code.
View 1 RepliesI have a GridView which is not bound to any DataSource. In my page load event I am writing this code:

I have a textbox named text1. I use an INSERT INTO sql statement on enter text1's data into my database. But there is a problem. Whenever I use ' in my textbox, I get an error for INSERT INTO statement uses the same ' to enclose string data. The code is like this:

OK So I know WHY I am having the error I am getting. I don't know HOW to fix it. Basically, if the user doesn't have a certain permission, I need to join another table. But .NET is so picky I can't just make two different queries in an IF statement and then use it outside of the if statement. I can think of some ugly work arounds for this, but I would rather not. I am fairly new to .NET I know just enough to be dangerous.

because of this: Dim l As IEnumerable(Of Company) its not just IEnumerable of a Company, its got the source in it. I have to explicitly select source to use it in my datagrid. Can I make Dim l something that will make it stop complaining?

I have a method to execute two "Update" sql statements.
The first one works fine and the second one I can't get to work for nothing.
Here is the entire method:
[Code]....
The error I am getting is "Incorrect syntax near '05'."
It is occuring on the next to the last line which is:
dc.ExecuteCommand(sql);
I update the variable "sql" first so I can debug. At the time it crashes the value of sql is:
"Update Blogs set Status = 'Archived', ArchiveDate = 06/22/2010 05:14:46 PM Where (BlogID != 1) and (Status = 'Published') and (AuthorID = 9e37e028-c205-4903-920e-e8643b30a724)"
It appears to be the ArchiveDate that is causing the problem here. The "05" is the hour of the time portion. Both ArcgiveDate and PublishDate are defined exactly the same in the database. If you look at the first dc.ExecuteCommand it does exactly the same
thing with PublishDate (DateTime column) in the same table and it works just fine.
Then I modifed the code and remove the ArchiveDate from the sql statement then I get the error:
"Incorrect syntax near 'e028'."
which as you can see is part of the AuthorIDs value in the where clause. So I am assuming both the date and the Guid / Author ID is causing problems. I have tried enclosing the values in quotes but I just cant make this work even though it seems to be working fine in other places.
I even remove the code for the author ID and left in the code for the ArchiveDate and it still does not work so I have proved that both are causing a problem.
My application includes BUILDING table with columns BUILDING_ID, NAME, TOWN_ID, I run the LINQ query listed below and need to append two letters to buildings.NAME based on TOWN_ID. I assume that I need to place an "if" or "select" statement inside the query but I can not figure out how to do that,

Right now I have an error if f.ParentID is null:
DataSet1.TreeItemRow[]
TreeItemRows = (from f
in tidt
where (f.ParentID == TreeItemId)

I have a drop down List 'DropDownList1' and I want to insert the selected value of that into a SQL Query. I'm working in VB and I cant seam to find a simple way of doing it. The bulk of my code is on my page using GridView to display the data back. I want to have check boxes at the end of each row on the table which once checked when the create option is selected the data from the selected rows is passed to a second page or Panel on the same page.
