I have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?

I have a problem inserting data into a table on a MySQL database using a VB.NET application. I have a simple form where when I set some data to the textboxes and I press a GO button, the code should execute a function called InsertCar() that takes all these values and insert them into the database and then return true if the transaction is done successfully or false otherwise. My problem is that nothing is being inserted into the table.

I'm loading my listview with records from a mySQL Table, which works great. But I'm having issues when I try to add records to another listview according the selected row in the first listview.
vb.net
Dim mysqlDataComm As New MySqlCommand("SELECT jan, feb, mrt, apr, mei, jun, jul, aug, sep, okt, nov, dec FROM data_table WHERE datum ='" & frm_main.Listview1.SelectedItems(0).SubItems(1).Text & "'", mysqlConn)Dim mysqlReader As MySqlDataReaderTrymysqlConn.Open() With frm_main.lstv_data.Items.Clear() mysqlReader = mysqlDataComm.ExecuteReader While mysqlReader.ReadDim lvi2 As New
[code]....
It works until ".Items.Clear()"... after that nothing happens and I really don't know what I'm doing wrong. No error, whatever.

I am having a problem with submitting html from a textbox into a mysql table. I would believe this to be due to "special characters".
The code I am using is,
vb.net
Dim html = (sdata.Text.ToString)
Console.WriteLine(updateRecord("INSERT INTO course (tittle, length, begining, price, about, table) VALUES ('" & TextBox1.Text.ToString & "','" & TextBox2.Text.ToString & "','" & TextBox3.Text.ToString & "','" & TextBox4.Text.ToString & "','" & TextBox5.Text.ToString & "','" & html & "')"))
MsgBox("Success! You have Successfully created a new course, " & TextBox1.Text.ToString)
Me.Visible = False
The error I get is:
A first chance exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll

My requirement is that I want to transfer selective data from listview to Inventory table based on ItemId. Like i have ItemId 1,2 3 4 to 32. I want that only data relating to ItemId 2,3,4 and 5 be transferred to Inventory table and the rest of data be transferred to other table.
why my code isn't deleting the selected row in my ListView from my SQL table? it says it works fine in run time and removes the seleced row from the ListView but when i restart the program its there again.
Obviously this is because my code isnt actually deleting the data from the SQL table but i cant work out why not? the code for my delete button is as follows
Private Sub btnDeleteTask_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeleteTask.Click Dim delete As DialogResult = MessageBox.Show("Are you sure you want to delete this customer?", "Delete Customer", MessageBoxButtons.YesNo, MessageBoxIcon.Warning)
