Databases :: Mysql Odbc Database - Syntax / Connection Not Close Errors
Aug 18, 2010
[Code]....
I can check whether username exists or not successfully but not for email. any ideas why it isn't working? Error message was that i did not close my connection. using System;
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.
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?
I am currently making a website on asp.net and i am creating methods using TableAdapter. I am connected to MySql using an ODBC connection. The select * from department will work perfectly for me but when trying to use parameters i am given an error message on the wizard. select * from department where name = @name gives me the error: Error in where clause near '@' unable to parse query text. also tried select * from department where name = ?: this gives me the error: No mapping exists from dbTypeObject to a known Odbc type.
I have a problem whenever i run my code i get the following error ERROR [42000] [MySQL][ODBC 3.51 Driver][mysqld-5.1.46-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 ' ('b'), ('Manager'), ('c'), ('d'), ('e')' at line 1 my code works with connector/net but my host does not have it installed so i've had to change my code to odbc which they do have, i have found out the syntax is different and changed my code accordingly my code is as follows
My code is to update a record if it already exists in database else insert as a new record. My code is as follows:
protected void Button3_Click(object sender, EventArgs e) { OdbcConnection MyConnection = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver};Server=localhost;Database=testcase;User=root;Password=root;Option=3;"); MyConnection.Open(); String MyString = "select fil_no,orderdate from temp_save where fil_no=? and orderdate=?"; OdbcCommand MyCmd = new OdbcCommand(MyString, MyConnection); MyCmd.Parameters.AddWithValue("", HiddenField4.Value); MyCmd.Parameters.AddWithValue("", TextBox3.Text); using (OdbcDataReader MyReader4 = MyCmd.ExecuteReader()) { //** if (MyReader4.Read()) { String MyString1 = "UPDATE temp_save SET order=? where fil_no=? AND orderdate=?"; OdbcCommand MyCmd1 = new OdbcCommand(MyString1, MyConnection); MyCmd1.Parameters.AddWithValue("", Editor1.Content.ToString()); MyCmd1.Parameters.AddWithValue("", HiddenField1.Value); MyCmd1.Parameters.AddWithValue("", TextBox3.Text); MyCmd1.ExecuteNonQuery(); } else { // set the SQL string String strSQL = "INSERT INTO temp_save (fil_no,order,orderdate) " + "VALUES (?,?,?)"; // Create the Command and set its properties OdbcCommand objCmd = new OdbcCommand(strSQL, MyConnection); objCmd.Parameters.AddWithValue("", HiddenField4.Value); objCmd.Parameters.AddWithValue("", Editor1.Content.ToString()); objCmd.Parameters.AddWithValue("", TextBox3.Text); // execute the command objCmd.ExecuteNonQuery(); } } }
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
The datatype for fields in table temp_save are:
fil_no-->INT(15)( to store a 15 digit number) order-->LONGTEXT(to store contents from HTMLEditor(ajax control)) orderdate-->DATE(to store date)
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 thinking the problem here is with my SQL Syntax, but I'm not sure and need a fresh pair of eyes to check it out. This is the code I'm using to connect to and then insert into the DB:
I created a DSN to the database, which is hosted on my machine. When I run the application I get this error:
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 'key, secretkey, uid) VALUES ('127090765-i3aZl71LPSVUCPZs9kHSYeBli0vWpbq0BaM1roYC' at line 1
But for the life of me I can't figure out what's wrong with my syntax...It's prolly something simple, but again, I need a pair of fresh eyes to look at this.
I have a problem that I can't figure out. I shall read an images from a column in a MySQL database. I use a simple aspx page and the codebehind file with the code below.
It is ok to read the image if I don't use any parameter value in the where clause, but if I use it, nothing is returned. I don't know if I have done anything wrong in the code. I have also tried to set a proper value on the parameter.value without success. So my conclusion is that the parameter sertup is wrong in my code.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim PictureID As Integer = Convert.ToInt32(Request.QueryString("id")) 'Connect to the database and bring back the image contents & MIME type for the specified picture
I'm having problem on passing parameter on odbc because it's not working at all. I tried this using sql and I have no problem at all. All are working fine. Is there a different syntax on odbc? Here's my code:

Or using mysql connector/net to use mysql. I'm having problem installing it because the visual studio integration is not working, so I can't find it on the data source provider.
I am trying to make connection to a remote database server and I am getting the following message. I think i have to grant access to the client maching from my database server.. How do i grant access to an ip addess?

I am with GoDaddy (yeah, yeah, don't want to hear it) and must use ODBC to connect to my MySQL database. The connections are working fine but I have a GridView/DetailsView parent/child relationship set up between 3 pages. I know that these pages worked with a .NET Connector locally but after I changed them to ODBC, I only get the first part of the page, nothing that depends on data being selected works. This has led me to believe that I must alter the way I pass parameters to the next request page. I have read some things about using a question mark but I cannot figure out how I should apply it to my page as most examples are in C# or VB. My page is mostly pure ASP.NET and I'm not sure if I still continue to utilize the asp:ControlParameter. the code below.
how to get GoDady to alter their medium trust to accept sockets???? That's all it would take
This is the page my employees will use to view the people in the database and then select them and have a details view of that particular cust_code (customer code) pop up to the right of the gridview:
[Code]....
This is the page ( UpdatePrefCustomers.aspx ) that my employees, who will be allowed access it (yes, I already know how to apply authorization but will do it last before deployment so it doesn't drive me crazy when I preview in browser), will use to add, edit, and delete from the database. It must be accessed first and the other two pages, prefcust_edit.aspx and prefcust_insertt.aspx are called from it by passing the parameter cust_code:
System.Data.Odbc.OdbcException: ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on '127.0.0.1' (10048)ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on '127.0.0.1' (10048)
I'm busy working on an ASP.NET Web Application (3.5) and can't seem to connect to a MySQL DB. I first created the entire application using a WinForms template and everything works 100%, but as soon as I move the exact same code to the Web Application, I can't connect anymore. Here's the code:
Code: public class DBC { OdbcConnection connection; public bool CreateConnection() { try { string connFormat = "Driver={MySQL ODBC 5.1 Driver};Server=[SERVER];Database=[DBNAME];User=[UID];Password=[PWD];"; connFormat = connFormat.Replace("[SERVER]", Properties.Settings.Default.DBServer);
[Code] .....
As soon as I try to create the new OdbcConnection instance, I get the error:
Code: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
As noted this works in a WinForms app, and even more strange is that I don't even specify a DSN name...
All I could find from reading through forums all over the internet is suggestions of downgrading the MySQL ODBC driver version, which I'd really rather not...
when i specify values in my update query the query works fine and the database gets updated, but when i use parameters in my query the database does not update here is the code i have written
my webserver is in the DMZ. The Database in the intranet. For connection from webserver to database the following entry is made in the odbc connection "TCPIP BCAST=NO;HOST=Intranet.Firma.local,Intranet_Spiegel.Firma.local,Intranet_Arbiter.Firma.local;PORT=2639}"
how to get this options in the connection strings working, or how i must modify the entitiy framework connection string to use the odbc entry?

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.
I'm using an ODBC connection to connect a SQL 2005 database to my ASP.NET app in Visual Web Developer Express. I'm finding that the expected functionality that tutorials review does not work for ODBC connected databases the same way as it does for SQL databases created in the Web Developer. For example, I can't use stored procedures because the option to create one is disabled in the Web Developer, and if I create the stored procedure in SQL Server Management Studio Express, it doesn't show up in Web Developer because Web Developer only finds the system stored procedures, not the user-defined ones. I've seen other cases as well where database management options in Web Developer don't work with ODBC databases.
Am I missing something in my setup, or is there an inherent limitation with ODBC connected databases? Or, is this a limitation with using the Express versions of these development tools?
protected void Button3_Click(object sender, EventArgs e) { //Create a connection to the database MySqlConnection conn = new MySqlConnection("Database=kid07025;Data Source=195.178.228.254;User Id=kid07025;Password=********"); //open the connection conn.Open(); //MySQL Query which updates the row where Anvandarnamn = Anvandarnamn (recieved from a cookie) MySqlCommand cmd = new MySqlCommand("UPDATE personer SET Information=?Information,Fnamn=?Fnamn,Enamn=?Enamn,Personnr=?Personnr,Adress=?Adress,Postnr=?Postnr,Ort=?Ort WHERE Anvandarnamn=?Anvandarnamn", conn); // Update with new text cmd.Parameters.AddWithValue("?Anvandarnamn", Request.Cookies["Anvandarnamn"].Value); cmd.Parameters.AddWithValue("?Information", TextBox1.Text); cmd.Parameters.AddWithValue("?Fnamn", TextBox2.Text); cmd.Parameters.AddWithValue("?Enamn", TextBox3.Text); cmd.Parameters.AddWithValue("?Personnr",TextBox4.Text); cmd.Parameters.AddWithValue("?Adress", TextBox5.Text); cmd.Parameters.AddWithValue("?Postnr", TextBox6.Text); cmd.Parameters.AddWithValue("?Ort", TextBox7.Text); cmd.ExecuteReader(); conn.Close(); RefreshProfile(); }
I don't know what I am doing wrong here, but the database doesn't get updated when I press the button.
I want to use MVC 2 with MySQL database. Is it possible?because my shared hosting limits the size of SQL Server database, but there is no limit on Size of MySQL database.MySQL seems to take less disk space than SQL Server database which is costly on the Internet.
