You can use it, but it's not a good idea. You should always use the most appropriate type for the data you want to store.

Let me put this in stronger terms NO YOU SHOULD NEVER STORE DATES AS STRINGS
Storing date as varchar is going to cause you problems in the future. You will see many questions here where the root cause is a date/string conversion.

Hi
please am new linq to entities, my question does linq support oracle or mysql? If there is any other database it support please list it out.
thanks

Why don't you just Google for "Linq Oracle" or "Linq Mysql" to find out whether they are supported or not?
By the way, there is a Linq forum for questions about Linq

Look into the compute keyword in BOL.
Compute avg(avg(calltime))
Caveat - this will give you 2 tables in your dataset when using dataset.fill

This is nt a sql problem as such, you need to refresh your data in your code - if you have a datareader close it and reopen it, or refresh your dataset etc.

When I said refresh your datareader or dataset thats what you need to do

conImage = GetDBConnection()
daImage.Fill(dsImage.Images)
If you re execute this you are refreshng your dataset with the revised data and you will see your changes.

Looks like you haven't properly specified the SQL Server you are trying to connect to. Check the help for SQLCMD - SQCMD -Help will probably do it.

This is a problem solving forum, we try to help you solve your coding problems. This looks like a straight request for code  . There are many samples and examples that do this already available.
Do you seriously think someone is just giong to write these classes for you? The only thing you are going to di is set yourself up to be flamed, deservedly so.

As you say "There are many samples and examples that do this already available" Why don't you provide the link?
I am not expecting the code for all the methods. I am looking for any example for any of the method mentioned in my post.
If you have solution pass it otherwise don't pass rubbish comments.

I've tried discussing this with you, it's plain you're not interested in discussing your problem, but just asking for someone to give you the code.

Christian Graus,
Let me clarify you, we have Fair Idea on Ado.net but in our project client have old Ado based COM Components using MTS and MSMQ. He wants us to convert that functionality of recordset and properties and events using the ADO.net and Microsoft Enterprise library.
we got some suggestion by writing the wrapper classes we can get the functionality.
We managed to write and map Ado.net table object to Recordset in wrapper class and we can able to manage the functionality of MSMQ and MTS using the interop services, but we are clue less to write the other properties and methods without using the ADODB Object.
We are looking for any clue or suggestion from anybody worked on wrapper classes on writing the properties / methods of ADO-recordset using Ado.net.

1) getBookmark()
2) setBookmark(currentBM)
I doubt you can do these, because you have no connection in ADO.NET, it's called and closed when you get a recordset.
3) Delete ()
Again, there is no concept of a current record, it does not exist. However, if you have a primary key, you can run a delete command based on the record you're looking at.
4) close ()
Your dataset does not connect to an open connection, it's not ADO, it's ADO.NET
5) getStatus()
6) getDataSource()
7) DataMember()
8) Update(Fields,Values)
9) ActiveConnection()
I am trying to google to help you, but all I am finding is your posts over the web asking this...
At the core, there is no active connection, no current record to delete or update, no data source in memory. ADO.NET makes a call and returns a view of the data. Your best bet is to work out how to do the same things, such as to make an update or delete call. There will be no one to one mapping of methods,.
