Access MySQL from NET application can be done as same as MS SQL Server by using MySQL Connector for Net. Just download that connector from MySql website and see their samples enclosed.

hi, I have a dataset, DataSet1, populated from a database table named "Sections" which is bounded to DataGrid1.
I want to remove a row if a user selects it in the datagrid and presses the remove button. here is the vb-code:
Private Sub cmdRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRemove.Click
If DataGrid1.CurrentRowIndex >= 0 Then
DataSet1.Tables("Sections").Rows.Remove(DataSet1.Tables("Sections").Rows(DataGrid1.CurrentRowIndex))
MessageBox.Show(DataSet1.HasChanges)
OleDbDataAdapterSections.Update(DataSet1, "Sections")
DataSet1.AcceptChanges()
End If
End Sub
But messagebox shows False, and the row is not actually removed from the database, ALTHOUGH DataGrid1 shows that the row has removed from dataset!
(I use the same method i.e. DataSet1...Rows.Add(..) and then the oleDbDataAdapterSections.Update(..) to add rows which works perfectly!! But the added rows are not removed using the same code from the database...)
I really dunno the reason and got confused!

i want to company that if today date is greater than do step 1 and if not than do step 2 and i m doing this
IF dbo.FormatDate(GETDATE()) > dbo.FormatDate('28/04/2006')
--Step 1
ELSE
--Step 1
but its not proper working i can do this with year, month and day individual comparison buts not proper way to acheive task.
can anyone tell me that what's the mistake in above code
dbo.FormatDate() is a function which extract only date from date and time.
Thanks

I'm guessing (becuase you've not provided the code) that FormatDate is a UDF that returns some value that you can test against. I don't know why you need to do this as you can check greater than/less than on a date already.
IF GETDATE() > '2006-04-28'
BEGIN
-- Do stuff
END
ELSE
BEGIN
-- Do other stuff
END
I would recommend that you always use ISO dates (YYYY-MM-DD) - that way you don't get messed around with cultural specific problems.

Hi there,
I am installating msde with my application using installshield (10.5) prerequsites(redistributable). The problem i have is that on windows 2000 after msde installation system require a reboot(there is no way out i tried all the commandline arguments but even if i am sucessfull in supressing reboot still sql script with my installation which create database don't get sucessful without reboot). To solve this problem what i tried is to use installscript and add a registryentry in runonce as my installation begins and delete it at the end of installation with another installscript custom action. The only problem is that i can't run my custom action prior to setup prerequisites get installed. I tried to set the sequence of my custom action to -5(means run first up) but still the msde setup starts prior to my custom action. Is there a way to run custom action prior to setup prerquesites or is there any solution to continue setup after msde installation?
Thanx for help in advance.
Qaiser.

Hi,
I need help on creating an SQL statement that will add up all the numbers in a given column of all the matching rows of data.
At present i have:
OleDbCommand cmdC = new OleDbCommand("SELECT COUNT (bookingNumbers) FROM tbl_Booking WHERE bookingWhen='"+addDays+"'", myConnection);<br />
cmdC.Connection.Open();<br />
covers = Convert.ToInt16(cmdC.ExecuteScalar());<br />
cmdC.Connection.Close();
But this just returns the number of matching records rather than the total of the data in these records.
Any help would be greatly appreciated!
Thanks!
Pablo

The SQL COUNT function returns only a count of records returned. You need to use SUM instead but you will be forced to use GROUP BY since SUM is a summerization function.

Hi,
Thanks for the reply.
Im new to .Net so could you give me an example of how to create this statement, and if possible how to run this code in c# .Net ?
Thanks!!!!!!

First of all, your problem is really SQL related. I am getting ready to go to work and I don't have time to leave a good example so here is how your SQL might look like:
SELECT SUM(bookingNumbers) FROM tbl_Booking WHERE bookingWhen='"+addDays+"'"
The "GROUP BY" might not be necessary. If it is do this:
SELECT SUM(bookingNumbers) FROM tbl_Booking WHERE bookingWhen='"+addDays+"' GROUP BY booingwhen"

The only thing I can think of is that it is a database that contains details of tenants (people that rent properties).
It might be useful if you provide the context in which you find this term.

I think they use the term Tenant Database when more than one organization share the same datasource.
I think it's relatively new term.
