I am trying to return a column value from a database table. I am not sure if this is the best way to do it but I would like to make a funciton so all I have to do is pass a sql string and have it return my value (or row). Here is what I have:

I have a Table, which contains a list of league players. Each season, we record their Points per Dart. Their total PPD for that season is stored in other tables and extracted through other queries, which in turn are imported to the master table "Player History" at the end of the season for use as historical data.
The current query retrieves each players PPD for each season they played, when they played last, and how many seasons played.
The code for Last season Played has become too long and unstable to use. it was originally created, and split into two separate columns because a single SQL was to long. (LSP1) and LSP2) which work, but as I add seasons, Access does not like the length of code.
In short, i need to find a more simple code that will look at each row, and look in that row for the last non null cell and report which column that last non null value is in.
So if a player played seasons 30 & 31, but did not play 32..but did play 33, the Column with the code should be titled Last Season Played, and for that Player, it would state "33" in that cell, indicating that this player last played season "33"

View 1 RepliesI'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

I'm trying to filter a DataView to return all the rows whose column x starts with a number: The following works in SQL Server:
select *
from dbo.Page
where Name like '[0-9]%'
However, when I try this:

I get "invalid parameter [0-9] with Operator Like" error message. What is the correct syntax to achieve my goal?
In my database MYDB I have a table called MYTABLE and I have a column called Description. I am saving a long description in there with multiple HTML tags.
How can i return the values and not include all the HTML tags?
Is this even possible? What will be the best way of doing this? In the SQL statement or in code behind? And how will I do it?

View 8 RepliesThis issue has a few different facets so I wasn't sure what topic to post it in.I have a DB query like this:A SELECT statement with an INNER JOIN of two tables: [programs] and [program_managers] then on an aspx page ProgramManagers.aspx, I list the Project Managers, ordered by the Priority field of [programs].
I take the query and put it in a DataTable.Then I loop through the rows 1 by 1, creating Labels, etc to display the content.
Now here's the issue: Because a given Program Manager may manage more than one program, when I display this way, the Program Manager's Bio etc, gets listed as many times as their are programs that they manage.

I have a little problem with a query. I'm selecting data using the between command, But when I select the initial date equal to the final date the query doesn't show data.I know that the problem is the format. In my database I got something like this:2009-05-22 15:32:52.000. But when I send the date parameter from ASP.NET Page I sent only the Date (2009-05-22).So, I want to fix this thing. I cannot change the Datetime inside the database.I was thinking adding 1 day to the final date, So when the user select the same date I change the range behind the scene and then show the data. What do you think?

I have a products table whereby I want to return a single row via a product id and use it as a data object.
I have used a .xsd dataset and a product class where I return a dataset and add the values into the product object that I created but I don't like having to write code like
"Product[0].ProductDescription" to get the product description. Is there a way of returning is straight as an object rather than a dataset?
Got a problem with regards to the file upload control on database updates. The problem is in my CMS, when a user tries to update content for a page it will add null to the fields containing the image path. What I need is for the system to check if the uploader has no image and if hasn't it has to do nothing. It can't add empty strings or null values as this will remove the original image path. Although they still need to be able to do image updates if the uploader has a file(this bits not a problem).
Here is a snipet of code to demonstrate what I'm trying to achieve.

In general terms, which way will require more server processing power and which way will return faster queries... if there is even a difference. The client's database is still on the dev MS SQL server but is essentially but the client has decided they want to collect two more fields of information. Both fields are going to be collection text data and probably varchar(300) will be sufficient for the column data types. Would it ultimately be more efficient to
Add two additional columns in the main table so the data is entered directly into each record, or Add an additional table (or two) with a foriegn key to the primary table that holds the info for each new field The SELECT statement for the main table could be modified to either add the new columns (a.NewColumn1 and a.NewColumn2) or it could contain nested SELECT statements that pull in the data from the other tables. Custom daisy-chained Insert or Update statements would be no problem and a cascade Delete relationship would take care of any deletions. I'm just trying to figure out which would be better from a performance standpoint?

View 1 RepliesI have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
Can my WebMethod return an XmlDocument as return type?
When I try to consume the web service I'm still not getting XML. It appears as though a reference to the method is being returned rather than say a string containing XML.
