I want to create an application where I need to enter date to the ms access database.
I am a bit confused regarding how to make the user to enter date. The options avaliable are:
a. Shall I use a textBox?
b. Shall I go for 3 drop down lists?
or something else.
Some more questions:
1. what date format shall i use? (dd-mm-yyyy, dd-mmm-yyyy, etc, etc or anything else)
2. What datatype shall i use to store the date in the database?
3. What SQL query shall i use to retrieve the data between 2 dates?
let me know if there are multiple options available regarding this application.
I want to make this application as easy as possible for the user.
I have a GridView; one of the columns displays concatenated records from a tables. to extract the records that are going to be concatenated and put in this column, i have used: FOR XML path('') and it works just fine for displaying those records. the problem now is the whole gridview can not be sorted anymore and gives me a 404, document not found, error whenever i try to click the columns to sort. here is my select statement for my sql datasource select command:
SqlDataSource2.SelectCommand = "Select a1.*, keyword = substring( ( SELECT DISTINCT ', ' + keywordName FROM keywords JOIN key_mm_articles ON key_mm_articles.keywordID = keywords.keywordID WHERE key_mm_articles.articleID = a1.articleID FOR XML path(''), elements ),2,500) FROM articles a1 WHERE title LIKE '" & titles & "' Order By a1.articleID"
I am wanting to write this in linq SELECT *FROM Store_InformationWHERE Date BETWEEN '12/03/2007' AND '01/04/2008'Can anyone give me an example?

I want to select dates that also fallin the range. Heres the scenario: I have an event from 01/20/2010 TO 01/25/2010. So right now it would only return a date of 01/20/2010. How could I return 01/20/2010, 01/21/2010 , 01/22/2010, 01/23/2010, 01/24/2010, 01/25/2010? Mind you only a start and end date are in the database.
I'm trying to work out how many 1st of Septembers have occurred between two dates.
i.e.
2009-05-1 and 2010-08-02 = 1
2009-05-1 and 2010-09-02 = 2
I know that we can do a dateDiff to determine the number of days between two dates, I'm just having trouble getting some logic together.
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

This query works perfectly on the query analyser.
But when configuring the Table adapter ,I try executing the query and i get 0 rows affected.
What could I be getting wrong in this case.
NB:Existing GalleryID has been supplied.
By right clicking on my database i created a query in server explorer. But where are this query stored can't find them back. I should aspect that their is a folder query's like there is a folder tables but this isn't the case.

how can we retrive records from sql-server between two dates. Dates are specied using DateTime datatype of C#. Also the stored date in sql is of Datetime type.
View 5 RepliesI want to be able to display the entries in this table based on the date and time of recorded in the entry.
So as an example:
Entry A only appears on Mondays at time X.
Entry B appears on Tuesdays at time X and Sundays at time X.
Entry C appears every day of the week at time X.
Entry D appears every day of the week but twice on each day at time X and y respectively.
I want to calculate the number of HOLIDAYS between two given dates. For example, to count the number of 'Fridays' and 'Saturdays' and any other holiday (can get from another table) in between two given dates.
For example,
Start Date: 16/07/2010
End Date: 22/07/2010
Holiday: 19/07/2010
OUTPUT: 3 Holidays (Since there are only two Fridays and Saturdays and one Holiday)
do also note that it must include count if the starting day or ending day is a holiday.
I have a web form that displays the results from a table. How can I compare the table between dates and display the differences of the table?

View 5 RepliesI've got a query such as
Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select
which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE
However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?
i have DateFrom and DateTo columns in tblLOgs.if they both are same then select only DateFrom else both selects.my procedure is ....do modification in them

where I'm going wrong with this SQL Query of an Access Database which populates a Datagrid,
From a calendar selection the user can select a From and To Date and I want the SQL Query to ONLY pick up the dates between these two values, the selection is fine it seems to be the sql query which is the problem ... (I have added dates rather than the text value to make it easier to get working ) the following query wil pick up dates outside of the selected values 01/08/2010 , 02/08/2010, etc
SELECT COUNT(*) AS Date_Installed, Date_Installed AS Expr1, Installed_By FROM Buildprocess WHERE (Date_Installed BETWEEN '20/08/2010' AND ' 25/08/2010') GROUP BY Date_Installed, Installed_By

I have a query that gives me the average number of days between 2 dates in the database. It gives an error saying line does not reconize the subtract method. What is the best way to do this, i prefere not to have to get the whole table as a list and loop though.
Using em As EE.EclipseEntities = New EE.EclipseEntities
Return em.OrderLines.Where(Function(w) w.Received_Factory_On.HasValue) _
.Average(Function(a) CDate(a.Received_Factory_On).Subtract(CDate(a.Sent_Factory_On)).Days)
End Using
