Databases :: Connection MySQL - Using ODBC Datasource - "syntax Error Near Page 1 At Select * From [categories]"

Jun 1, 2010

I have installed MySQL and set up an ODBC driver to point to a database in MySQL. In ASP.NET I have defined a connection string to attach to this MySQL dtabase.

<asp:SqlDataSource
ID="SqlDataSource2"
runat="server"
ConnectionString="<%&#36;
ConnectionStrings:MySQLConnectionString %>"
SelectCommand="SELECT
* FROM [categories]"
ProviderName="<%&#36;
ConnectionStrings:MySQLConnectionString.ProviderName %>">
</asp:SqlDataSource>

However in ASP.NET connection wizard, although the tables are shown, no colums are shown and when I attempt to run the page which uses this datasource I get an error message about a syntax error near page 1 at 'Select * from [categories]'. how to use an ODBC (MySQL) datasource in ASP.NET?

Databases :: Connection To MySQL Database

May 15, 2010

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:-

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");

// trying to update the table to add the image

Databases :: MySQL Connection No Longer Works After Publishing Project

Jan 21, 2011

To start, I am a new web developer. I have been writing C# for about a year, but just recently learning web development. I wrote an application that connects to a MySql database and when I run it on my localhost it wokrs great! I created a ubuntu server on amazon ec2 and it is hosting my MySql server. It is up and running just fine. I created a windows 2008 server instance on amazon ec2 to host my asp.net project. I published my project to my windows server and I went to my public IP address and my site was there! it was so easy...

However, when I went to login, I recieved this error: Could not load file or assembly 'MySql.Data, Version=6.3.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified. I made sure the correct connector was installed on ym server. I have the most recent mysql connector installed. I do not know how the publish actually works. I saw some forum posts that said maybe I was missing DLLs from my bin directory but I cannot even find my bin directory for my project on the server. I also saw some posts about changing the web config file, but that was gibberish to me at this level.

OdbcCommand MyCmd = new OdbcCommand(MyString, MyConnection);
MyCmd.Parameters.AddWithValue("", HiddenField4.Value);
MyCmd.Parameters.AddWithValue("", TextBox3.Text);
using (OdbcDataReader MyReader4 = MyCmd.ExecuteReader())
{
//**
if (MyReader4.Read())

I am getting the error as: ERROR [42000] [MySQL][ODBC 3.51 Driver][mysqld-5.1.51-community]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order,orderdate) VALUES ('04050040272009',' &' at line 1

Databases :: A MySql Error Causes Web-app Stop Responding?

Feb 7, 2010

I am working on an ASP.NET C# web application in Visual Web Developer Express 08', with MySql database.

Everything works just fine, except one problem that drives me crazy for few weeks...

My application randomaly (or not) stop responding, or just freezing for couple of minutes.

I am sure that the problem is connected somehow to my connection with MySql db.

In the debug window in VWD I get over and over the line:

"A first chance exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll"

Note that in each page load I call a function that kills all sleeping MySql connections, so I don't really think that my problem is 'too many connections'.

The error isn't constant, and not occures only in one page, it occures in many pages (that contains mysql access code), randomaly.

Databases :: MySQL And Asp Table Adapters - Error When Trying To Use Subquery

Nov 1, 2010

I have been trying to create a sql statement that uses a subquery to join 2 oracle tables to create a strongly typed table adapter. For example:

Select productName, (select categoryName from categories where categories.category_id = products.category_id) as Category from Products

The ASP .Net tutorial I am working through recommends using subqueries instead of joins for the insert, update and delete commands to be automatically generated by Visual Studio 2010. When I click Finish in the table adapter wizard I get the following error (I am using MySQL version 5.1 and the MySQL Data Connector 6.3.5)

Generated SELECT statement.
Error in SELECT clause: expression near 'SELECT'.
Error in SELECT clause: expression near 'FROM'.
Missing FROM clause.
Error in SELECT clause: expression near','.
Unable to parse query text.
