a user will choose a period of time (from this date to this date) with a calendar ,, and then i want to get from DB all Invoices that were created within this period ??
each Invoice has a Date saved in Database..
This is the sql select statement i am using:
SelectCommand="SELECT [invoiceid] FROM [invoices] WHERE (([location] = @location) AND ([name] = @name)) AND date BETWEEN '"+ (fromdate.SelectedDate.ToShortDateString()) +"' AND '" + (todate.SelectedDate.ToShortDateString()) + "'">

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 situation where a query returns ~20 columns, but at any given execution only 5 of the 20 will have non-NULL values. The remaining 15 will contain null for every row in those columns.
I need to figure out which of the 5 columns have values. I am using a SqlCommand. How would I best approach figuring out these 5 columns?

There may be a lot of data in the Blogs table. What if all I wanted was say BlogID, BlogTitle and BlogAuthor and nothing else, is there a way to do this in an effort to make the sql more efficent?
Along the same lines in my DataContext (.dbml) file I added some associations between some of my tables. This makes coding nice when I do a linq statement that will join those tables automatically for me but my concern is does it do that everytime, thus making all my linq quieries inefficient?
How do I select multiple columns into IQueryable<Employee>?
View 2 RepliesIs there a way to do a
"select * as"
and rename all columns with some prefix, rather than having to name columns individually? Or better yet, when doing a join and getting all columns from both tables, how do you identify them uniquely in the VB where some columns have the same name?
there are multiple rows with same SubContact_No and with same value of some columns. for a single column I am firing query like
Select distinct (Financial_Status) from mtblSub_Contract where SubContract_No=@SubContract_No";
it's working fine.... (it's ok with a Single column)
But Now I need multiple columns value so how to query for this.
Select distinct (Financial_Status, colums2, column3) from mtblSub_Contract where SubContract_No=@SubContract_No"; is not working
So how to do that.
I would like to select some columns from a Datatable, I mean, something like Select Name, Surname, ID,

This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords
FROM (Merchandise)
WHERE Keywords LIKE @term
The only other thing I can think of the gain this level of functionality would be to combine them into a new table.

I have a problem and i cant understand it.
My code :
strSql = "select * from tblannouncements where announcementdate = " & Date.Today
conn = New SqlConnection(strConn)
cmd = New SqlCommand(strSql, conn)
conn.Open()
dtr2 = cmd.ExecuteReader()
GridView6.DataSource = dtr
GridView6.DataBind()
It works but i dont receive any record and when i remove the = and enter a >
then all the records are displayed.I use datetime as data type in my database.
I also use this to add records if has anything to do with my prob but the records are added fine.
strSql = String.Format("Insert into tblannouncements values ('{0}','{1}')", txtAdminannouncements.Text, Date.Today)
conn = New SqlConnection(strConn)
cmd = New SqlCommand(strSql, conn)
conn.Open()
cmd.ExecuteNonQuery()
conn.Close()

I have a table called 'Customer' that contains customer information. One of the fields is named "CustomerType". Each record in the 'Customer' table will contain the value of either "C", "I", or "O".
I have a form that contains a "check box list" named "Type". There are 3 values in the "check box list". The values are "C", "I", and "O". The user can select one or more of these values. I have a button on the form named "btnRunQuery.
When the user clicks on the button "btnRunQuery" I want to exectute a query that selects the records contained in the "Customer" table where the value in the field "CustomerType" equal the values the user selected in the "check box list". Example: If the user selected "C" and "O", then I want the select query to select all records that contain either "C" or "O" in the field "CustomerType".
I assume that what I need to do is to capture the values that the user selected in the "check box list" and put them in a variable. Then I need to format the "Where" statement in the query and add a "Parameters.AddWithValue" command.
I've got a gridview which works fine. I use dropdownlists which are filled with distinct values of the columns. So when I select an item in a drompdownlist the gridview refreshes based on the selected value. When I have a column which uses string values, I can start the filter with a default % value to use in my select paramaters. But when I have a date column, I can't use that. I use a datasource for the gridview and I prefer to leave codebehind out if this is not needed. Now I use >= in my gridview select to show all rows. but I want to use only = to make the filter work correct when I select a date in the ddl and use the selectedvalue in the gridview selectCommand
<asp:DropDownList ID="ddlUpdateDatum" DataSourceID="dsPopulateUpdateDatum"
AutoPostBack="true" DataValueField="UPDATEDATE" runat="server"
CssClass="selectinput" AppendDataBoundItems="true">
<asp:ListItem Text="All" Value="01/01/1900"></asp:ListItem>
</asp:DropDownList>
<asp:SqlDataSource ID="dsPopulateUpdateDatum" runat="server"
ConnectionString="<%$ ConnectionStrings:GAMSYSTEMSqlServer %>"
SelectCommand="SELECT DISTINCT(UPDATEDATE) FROM [messages] ORDER BY UPDATEDATE ASC ">
</asp:SqlDataSource>
And I use this in the gridview datasource:
<asp:SqlDataSource
runat="server"
ID="dsGridview"
ConnectionString="<%$ ConnectionStrings:DBSqlServer %>"
SelectCommand = "SELECT * FROM [messages] WHERE AND UpdateDatum >= @UpdateDatePar ORDER BY UpdateDatumDESC"
>
<SelectParameters>
<asp:ControlParameter Name="UpdateDatePar" ControlID="ddlUpdateDate" PropertyName="SelectedValue" Type="string" />
</SelectParameters>
