May I know in SQL Server, what is the similar syntax for %TYPE in Oracle, i.e. the variable defined will follow the data type defined in the database column?
View 3 RepliesI'm doing a transaction type that is similar to iBank where people can add their payee. In my SQL database, I have a transaction table which has the date variable. I would like to set in a way that if the user did not express interests to activate the payee, the record will be expired after 1hour.
SELECT @Date = GETDATE()
SELECT @ExpiryDate = DATEADD(hh,1,getdate())
INSERT INTO PAYEETRANSACTION (CUSTID,PAYEETRANSTYPE,PayeeTranDetails,STATUS, PAYEEACCNUM,PAYEEACCTYPE,PAYEENAME,PAYERINITIAL,REF,Date, ExpiryDate)

I would like to monitor all the queries running under Oracle which are being fired. Looking for some good UI tool for Oracle similar to Microsoft SQL Server Profiler.
View 1 RepliesI have a textbox and what I would like to implement is basically a situation similar to what you have in google when you type in a word. In otherwords,
in the textbox when you type in J, it should generate a list of names that starts with O in alphabetical order, then next when you type in o, so that now you have Jo, it should generate a list of names instead that now starts with Jo in alphabetical order, then again when you type in h, it should generate a list of names that starts with Joh and so on.

I have the identical code for another page with the exception of the field names and it works fine. The only thing I did differently, as far as I know, is I copied the asp and code behind from the page that works into this page and manually changed the field and table names. I don't know what the problem is. Does anyone see any problems?

I have an Interface that has its concrete class defined via a factory. Because of this I found no way to use the Interface tpye directly in my LINQ quesry so I had to use the concrete class types to creat a generic list. The LINQ query works but after calling.ToList() on the LINQ query result I get a List(of MyConcreteClass), but I need a List(of IMyConcreteClass). I have tried everything I can find: .Cast, Ctype, implicit casting, etc. but I always get back one of the (2) messages (depending on if I attempt to cast)message:
"Unable to cast object of type 'System.Collections.Generic.List`1[MyConcreteClass]' to type 'System.Collections.Generic.IEnumerable`1[IMyConcreteClass]'."
...or
"Unable to cast object of type '<CastIterator>d__aa`1[IMyConcreteClass]' to type 'System.Collections.Generic.List`1[MyConcreteClass]'."

I am making a website to store invoices so i can mail them to clients. So i got a table for clients, invoices and one with invoice products/services. When an invoice has no products/services added to them and it returns null i get the error "the null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type."
I just started with linq. Before i always used mysql. Mostly i just had to call data from 1 table so forgive me if my linq query isn't really correct.
Dim invoices = From i In db.invoices _
Group Join p In db.products On i.id Equals p.invoiceId Into invoiceProducts = Group _
Select New With {i.client.naam, i.titel, (From iP In invoiceProducts Select iP.prijs).Sum}
i show the client's name, the title of the invoice and the total amount the clients will need to pay for products and services.
We are working in a new N-Layered application with EF4 as ORM. As a requirement, we need to give support for both SQL Server and Oracle existing databases.
Our wish was to build a single EDMX model and then generate our business entities from a TT file.
The main problem was that database providers may generate different .NET types from our database field types. In this case, we'll have different EDMX models and then different auto-generated entities, which is more or less the same as have two different applications.
I don't know if we could have different SSDL files with specific database information (one for Oracle and another one for SQL Server) in separete files and share CDSL and MSL information for both databases.
Would be this solution possible?
Someone knows some other way to work with Oracle and SQL Server using EF4?

It inserts a new record into a single table. The PK is a field named QID.what the equivalent Update code would be? I'm not sure of the syntax for the Update values (old and new) and Where clause.I'm assuming something beginning with: existingQ.Update
here is my update query syntax.my problem is.if i update only logo1 and logo3 with null logo2 and img null then my query should be update the other record.just dont update null value record but other should be update.but below my query can not update any record.
UPDATE tbitem set itemname= @itemname,note=@note,
price=@price,qty=@qty,logo1=@logo1,
logo2=@logo2,logo3=@logo3,img=@img
where id =@id
and @logo1 is
null and @logo2

Where can I find documentation on the syntax that is expected for LinqDataSource.Select? It seems to be different from what I would do with Linq inline in C# code. For example, concatenateing something in Linq I would normally just do this in the projection:
new { FullName = (person.FirstName + " " + person.LastName ) }
However, with a LinqDataSource the only way I've found to do this is like this:
new ( String.Concat(person.FirstName, " ", person.LastName) as FullName)
I literally spent hours trying to figure this out, and only succeeded when I found a blog where someone gave this verbatim as an example. So I still don't understand why the syntax is different, the braces versus parens, aliasing, Concat operators. Next time I do this I want a better understanding so I am not playing this guessing game. It's like being handed a compiler, and trying to write a program when you don't know what language the compiler compiles.1. Are there different "flavors" of Linq? Like a VB Linq, and C# Linq?2. If so, is the LinqDataSource using a VB flavor of Linq?3. Really, what is really important to me, where can I find documentation on this particular falvor of Linq that the LinqDataSource expects? The documentation for the LinqDataSource itself gives nothing more than extremely simplistic examples.

I have a website in which code on the production server runs no problem. The same code on my local machine or test server produces the mess seen at the end. The exact same code. Additionally, upon trying to preview any of the table adapters in the dataset I get "DataSet1.thename could not be previewed. The provider is not compatible with the version of Oracle client"
The app is SQL Server. It always has been. It has never used Oracle. Does anyone have any insight on how to fix this? As it is now I can't do anything with my dataset. I can't edit anything in there because of this complaint about Oracle.
