Inserting Data Into A MySQL Table Using .NET?

Feb 10, 2012

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.

Imports MySql.Data.MySqlClient
Imports System.Data.Sql
Imports System
Imports System.Data

MySQL Data Reading, Inserting, Updating?

Apr 22, 2010

I am a bit of a newbie when it comes to vb.net and databases and I have a small favor to ask anyone I am looking for a very basic example on how to connect, read, update and insert data into remote mysql database. I have successfully connected to my database with the code below,, and for the moment I am just trying to LIST data from it in a listview control,, and then would like to find a way to insert data into it and update data.

Al examples I find on the net are too long and usually have too many unnecessary data around the code I need so I get a bit lost in it.Can anyone point me in the direction of SIMPLE examples that are easy to follow or provide a bit of useful code I could learn form.

Inserting Data Into Db Table With VB 2008

Oct 28, 2009

I'm trying to insert Username, Password, and Account Balance data into my SQL Database. The code debugs correctly, but when I run the program, I'm not able to use the information I registered with to login with. (I have a separate form that lets me login with a username and password, and that works fine, so it has to be something to do with my register form.) Was this enough information?

Data Logging Application That Stores Data In A Table In A MySQL Database?

Dec 18, 2010

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?
