C# - Sql Select Statement That Will Give The Latest Result If Possible
Mar 30, 2011
I have a SQL statement as below
SELECT [Motor]
,[Time]
FROM [logger].[dbo].[motor]
WHERE day([Time]) = day(getdate())
ORDER BY [TIME]
This is a very basic table that gives me the status of a motor at a given time. All i want is a select statement that will give me the latest result if possible. I can get it so it gives all of todays results but if i could get it that it only displays the latest result that would be great.
Im using SQL Server 2005 and im using stored procedures. Is this possible? i need to get a number of results and do it in one SELECT statement or just one result set. Im using MS Chart Controls for reporting and they cant seem to process multiple result sets this is my problem, so basically to run a barchart i need to assign a column to the X axis and a column to the Y axis and it will then display my results.
My stored procedure below returns a result set with columns subpolicy_name, building_name, floor_name, room_name and total_savings. Im just wondering is it possible to split my total_savings column into 4 columns, for example subpolicy_savings, building_savings, floor_savings and room_savings, i need everything in a separate column. If you run this stored procedure you will see the result set.
I have a sql table (ProductsOffers) in which I store all the offers posted for each Product it consists of columns

I want a sql sentence or function that let me select the latest offer for each product. When I select by date it returns the last inserted offer and they may have repeated products and also there will be some products not appear in the result. how can I get a result with the latest 10 Offers for all my products with one offer per product

I have restricted the web login used by my ASP.Net pages to only run procs and pull data from views, it never has direct access to tables. My problem is if I add a new proc or view I have to modify the login's permissions to give access to the new items. Is there some way I can set the login to automaticly have the correct permission to new views/procs I add?

How do I select a column with the latest "datetime" data type, in Visual Web Developer 2008, ASP.NET 3.5? In the config data source dialog my WHERE options are greater than cookie, control, etc... but I would like to select where the datetime is the latest in the table. (Select row from table where datetime is last updated....)
EDIT - This will be for a specific user in the table, i.e. Select row in table from specific current userid WHERE the row was his latest updated entry.

I have two dropdown list, which is 'names' and 'types' and it's being populated by a dataset. It contains an additional item "-- ALL --" to indicate that all items of a particular field are being shown. I have an SQL select statement to filter the records according to the selected item of the dropdowns. I used a select statement to bind the records to a datagrid with regards to the selected items.
SELECT * FROM table where name = ddlnameselecteditem AND type = ddltypeselecteditem
The problem now is when I select a name from the names dropdownlist and types dropdownlist has a selection of -- ALL --, there would be no return records because there's no such thing as '-- ALL --' record in column 'types' i'm querying. I need to display rows of the selected 'name' while still showing all the 'types'. How could I achieve this? I think I need to avoid the '-- ALL --' item from the dropdownlist.
I'm pretty new at ASP. I've got a sheet I'm trying to modify using an IF statement. I tried putting them in, in different ways, but it either shows up in the form or I get the options multiple times
[Code]....
i have a variable picked up elsewhere strArea, so I was trying to do something like
[Code]....
I have tried putting the if's in different places, as well as case statement but usually I end up with my drop down option list as 1 1 2 1 2 3
I'm trying to pull a list of clients that have both of two codes in the code table. Here is what I have tried and it does not return any rows. I know that there are clients that have both codes.
I have records in the datatable which I have retreived from xml file.
Dim docDataSet As New DataSet Dim docReader As New XmlDocument Dim xnl As XmlNodeList docReader.Load("UserProfile.xml") xnl = docReader.SelectNodes("/Users/user") For Each xn As XmlNode In xnl Dim xr As New XmlNodeReader(xn) docDataSet.ReadXml(xr) Next xn Dim Dm_table As DataTable = ds.tables(0)
Now what I want to do is execute a select query like below:
Select * from user where userid in (select ID from Dm_table)
Retreive the records from the User table based on the ID's in the datatable.
sql_select = "SELECT auid FROM tbl_auAccount WHERE username='" & IarUN & "'" 'Step Three is Creating Connection Object and opening the database 'Add Error Trapping Later con = Server.CreateObject("ADODB.Connection") con.Open(data_source) 'Step 4 is to Execute the SQL Command con.Execute(sql_select) 'Step 5 Done. Close the connection con.Close() con = Nothing
This works fine, but I want the returned id (which I will right code to make sure it is not null and that it is only one returned) to show up as a label (or the text of a label)
