Here's the situation. Due to the design of the database I have to work with, I need to write a stored procedure in such a way that I can pass in the name of the table to be queried against if at all possible. The program in question does its processing by jobs, and each job gets its own table created in the database, IE table-jobid1, table-jobid2, table-jobid3, etc. Unfortunately, there's nothing I can do about this design - I'm stuck with it.
However, now, I need to do data mining against these individualized tables. I'd like to avoid doing the SQL in the code files at all costs if possible. Ideally, I'd like to have a stored procedure similar to:
[Code]...
Is this even possible in SQL Server 2005? Alternate ways to keep the SQL out of the code behind would be welcome too, if this isn't possible.

I made this procedure re-use a select query:
[code..]
And I use it like this if I would want the selected value placed in a textbox and it works fine
[code...]
However if I want the value to be passed in a string like so:
[code...]
The string ends up having an empty string value. How do I assign the value I queried to that String?

I have a datatable which has 5 column. It is possible to copy only its 2 column in and save it into new datatable.I used this code but it copies all the 5 column
Code:
Dim qry As DataTable = (From obj In temptable Where obj.Item("Column1") = 0 _
Select obj).CopyToDataTable
i used this one but it is not supported
Code:
Dim qry As DataTable = (From obj In temptable Where obj.Item("Column1") = 0 _
Select obj.item("Column1"), obj.item("Column2")).CopyToDataTable

Is it possible that a user input to a textbox like '12500', but vb shows it
'12,500' at the time of input.
But at the saving time vb should to read the '12,500' as '12500'.

I have an unbound datagridview that has 2 columns. Both columns contain numeric data only and will only go to 55 in count. How do you sort a Datagridview Column in collating sequence? I basically want to sort from 55 down to 1 and 1 to 55 in their respective numerical order.

I have a data table, i want to add a new column on that table, the data in that new column will depend in the data from another column. Now i can think of two ways to accomplish this, first is loop through the whole table and do the statements to get my new columns appropriate data. the second approach would be to give the new column an expression, then convert the table to xml (to remove the expression) then convert the xml string back to datatable.
Now, is there any other way around this? what could be the most optimized way in solving this task?

I have a large data.DataTable and some formatting rules to apply.For example, the LASTNAME column has a value of "Jones" but my formatting rule requires it be 10 characters padded with spaces on the right and uppercase only. Like: "JONES "My initial thought is to loop through each row and generate a string. But, I wonder if I could accomplish this more efficiently with a DataView, LINQ or something else.

First I tried getting a SQL query into an array, and then mail it. Made the data incomprehendable. So someone told me to use CSS to build a table format, filling it with the array. A LOT of hard work (since I had to learn css all the way from "what is a css".
Then I was told "Array? why use array when DATATABLES are soooo much easier"
So here we go again. "What is a datatable, and how does it work"
