Databases :: How To Receive An Individual Field From MySQL
Aug 21, 2010
I was wondering how to receive an individual field from my MySQL database.
I have been able to get a row, but what I am trying to do is get a name from my database and set it into the HeaderText in my DataGrid.
The way I am trying to do it at the moment is
[Code]....
This doesn't seem to get a value from the GetValue, but if use
[Code]....
it will bind my data into the grid.
I just want to be able to change the HeaderText in the first coulmn of the DataGrid from one table and have the DataGrid be filled from another table.
I can fill the DataGrid its just changing the HeaderText that I am having trouble with.

I am using a simple Login function and need to record individual field values from MySQL database to compare with inputs.
My connection code:
Dim myConnection As MySqlConnection
Dim myDataAdapter As MySqlDataAdapter
Dim strSQL As String
myConnection = New MySqlConnection("Database=mydatabase;Data Source=xx.xxx.xx.x;port=3362;UId=myID;Password=1234;")
strSQL = "SELECT username,password FROM Login WHERE ID = '" & 1 & "'"
myDataAdapter = New MySqlDataAdapter(strSQL, myConnection)
myDataSet = New Dataset()
myDataAdapter.Fill(myDataSet,"Login")
I have confirmed it is connecting by adding the following GridView.
GridView1.DataSource = myDataSet
GridView1.DataBind()
My problem is isolating the individual field values.

Using MySQL 5.
In my SAP.NEt project, defined a constant:
public static DateTime NullDateTime = DateTime.MinValue;
I have a function:
protected static DateTime GetDateTime(DataRow row, string columnName)
{
return (row[columnName] != DBNull.Value) ?
Convert.ToDateTime(row[columnName]) :
Globals.NullDateTime;
}
In the source code:
public DateTime StationFeedTime{ get; set; }
StationFeedTime = GetDateTime(row, "StationFeedTime");
I ran a SQL to fetch records from MySQL, this field is Time field in MySQL.
Got an exception inside the function:
Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.

I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.

I just moved to a new 2008 64 Bit Server. We are using MySQL, now also the 64 Bit version. Now I found out that there is a 64 Bit ODCB Driver, but not an 64 Bit Net/Connector.
Is that an issue or is the .NET Connector by default 32 and 64 Bit?

I did all the instructions which are in the following link: [URL] in order to do a connection between MySQL database and ASP.NET but I did not successed. Sometimes, it told me that I have a mistake in the <asp: button> and sometimes it told me that I did a mistake in calling (addImage) method. And this is my whole code:-
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="HW5._Default" %>
<script>
public class DataAccess
{
private string _strConn =
@"Driver= {MySQLODBC 3.51 Driver};SERVER=localhost;DATABASE=test1;";
private OdbcConnection _objConn;
public DataAccess()
{
this._objConn = new OdbcConnection(this._strConn);
}
// This function adds the Images to database
public string addImage(timestamp id, byte [] data,string extension)
{
string strSql = "SELECT * FROM File";
DataSet ds = new DataSet("Image");
OdbcDataAdapter tempAP = new OdbcDataAdapter(strSql,this._objConn);
OdbcCommandBuilder objCommand = new OdbcCommandBuilder(tempAP);
tempAP.Fill(ds,"Table");
try
{
this._objConn.Open();
DataRow objNewRow = ds.Tables["Table"].NewRow();
objNewRow["Extension"] = extension;
objNewRow["Data"] = buffer;
objNewRow["ID"] = id;
ds.Tables["Table"].Rows.Add(objNewRow);
// trying to update the table to add the image
tempAP.Update(ds,"Table");

I´m involved in a project that requires MySQL interaction, and I´m designing (or programming) the front end interface. SCENARIO: I´ve a MySQL database. (Now... Imagine a Webpage.aspx). I have a table inside the page with 2 rows: The first row has 3 columns... yes, cells!!, and the another one has no columns. In the first cell (1 row, 1 column) I have a treeview with a panoramic of my database (Treeview-Datasource: XML file that I build by myself with the hierarchy of my database). Then, in the 2nd cell (1 row, 2 column) I have a Radiobuttonlist; the aim of this cell is show only the name of every data placed in the selected entity (located in the treeview). And in the third cell (1 row, 3 column) I have 3 buttons: the first one is "NEW" (Should create a new item in the entity of the database - selected in the treeview) the second one is "EDIT" (Should edit the item of my database_entity selected in the radiobuttonlist)
And the third one is "SAVE"... (No words!!)
In the fourth cell (2 row, unique column)I have a FormView. To fill data, to arrange it in two columns, and to show textboxes allowing me introduce information to perform the button actions. I´m new in this, but I´ve seen that probably, I can make it using views (programming them in the database) or using XML files (declarating and querying my database as well as I want) but, in any case, the two ways requires build a view or xml file for every entity of my database that I want modify. I´m Sure that all of us know a short method or something.

I try to work with MYSql (because it's free) and I saw that the colums are different then when they are exployed in MS SQL?
Why is this? The most strange differents is that in MySQL there is no applicationId in the membership table.
This differents in tables cost me more time to do a export and import from MS SQL to MySQL.

But when in ServerExplorer I try "Add Connection..." I can't find "MySql Database" in the "Choose Data Source" dialog box?
