Connecting To MySQL Using Connector / Net 6.8.3
May 13, 2014
I'm trying to connect my app to my database hosted on my web space. I have a newbie query.Do I have to install Connector/Net 6.8.3 on my web space's server, or, can I install it locally and just change a config file of some sort on my server version? If the latter is possible, what is my best (and easiest) way of developing / testing in two DB environments? the testing server will be my online one so I don't mind having to manually edit something each time after I publish it.

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?

My local computer is 64 bit but the downloads for the .Net mySql connector found here:[URL]are 32 bit. I installed the 32 bit file however, whenever I try to input any new connector information after the 1st keystroke the box disappears. So I'm assuming that it has more to do with my machine being 64 bit rather than 32. Is there a 64 bit version of this connector?
UPDATE:
It is the Add a Connection box.
After I enter anything into any of the textboxes the above box just disappears.

environment: W7 Ultimate 64, VS2008, Mysql 5.1.45, Connector .Net 6.2.2
.aspx environment: a DropDownList (DDL) triggers a DetailsView (DV). All functions (select, edit, new ...etc) work fine.
Now, in the same .aspx page I use Event "SQLDSDVKlient_Inserted" to get the Last inserted record ID using "ExecuteScalar" method! This to fill the DV with the just created record using "New" (see code below).
on "cnn.Open()" I get below error msg; Event code 3005!
Some additional info:
a) keep in mind this all happens in the same .aspx page
b) In the MySQL wizard (5.1.45) I clicked the "allow remote connections".
c) the ConnectionString is copied out of web.config (remind you: all 'normal' DV functions work fine.I.e. I certainly can connect to my MySQL DB.)
d) When using, in ConnectionString, the parameters "Allow User Variables=True;old guids = true" I get, on statement "cnn = New Data.SqlClient.SqlConnection(connString)" a msg: Keyword not supported"; so I removed it.
e) without above connectionstring parm I get on statement "cnn.Open()" below error msg: where I need help!
Questions:
1) why does the system suddenly bring the remote connection into play?; I'm always on the same machine, same .aspx page!
2) what is the role of the "mysql connector.net" (6.2.2) in this scenario ?

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:
[Code]....
Here is the prefcust_edit.aspx page:

Here is the prefcust_insert.aspx page:

I have Connector/NET working on my windows 2008 web server. We are moving the MySQL DB from localhost on that windows 2008 server to a new Linux server. The tables are copied over. I can connect to them in the cmd line using all the same credentials.
When I try to connect via my ASP.NET application I get the ambiguous Error:
"Unable to initialize provider. Missing or incorrect schema."
All I changed was the server name in:
<add name="LocalMySqlServer" providerName="MySQL.Data.MySqlClient" connectionString="server=MYSERVER; database=MYDATABASE; uid=MYUSERID; password=MYPASSWORD; pooling=false; character set=latin1" />
If I change it back to the old server name, it works again.
Why am I getting this error? Do I need to change something else?

I've installed the Components from the links below. But I still can't find any SQL references when I try to add them? I'm wondering if anyone would know the reason for this? I just started with asp.net. I've found several other questions regarding code for connecting but I can't find anyone who've had trouble with the Connector/components before?

While working with LINQ to ENTITIES I see that there is only a way to use stored procedure that is returning one entity only, or a view that is a join of two entities.
But what if I need in ASPX page to get two tables that there is NO connection between them, no join can be done between them at all.
I have one Stored Procedure that return the two tables, but entities don't support this right now.
I can split them to two Stored Procedure and call each of them separately.

I we have created a website that requires users to login. It used forms based authentication and sql server to validation the login credentials.
Should we need to purchase an external connector license from microsoft to be able to host this site on a windows .net platform.
Edit: More information about external connectors. In microsoft licensing world there are cals for users connecting to the windows server software, external connectors are unlimited cal licenses.

I just downloaded and installed the most recent MySQL .net connector, 6.3.6 and it connects to the DB just fine. My problem is with the web.config settings I have set for it. It seems that theMinRequiredNonAlphanumericCharacters property is hard coded to '1'.I've changed this to 0, 5, or any other number. I even setup a web page to just display the properties of the provider. If I change the values in the web.config, the values update. It seems that MinRequiredNonAlphanumericCharacters won't change.
[Code]....
Again, the DB connection works just fine, reason I did not post the connection string. The min password length at 44 was just for testing.
[Code]....
Of the three I only tested, only MinRequiredNonAlphanumericCharacters stays at '1' no matter what I change it to in the web.config. I even changed it to 'abcd' and received no .NET runtime errors. Me thinks it is hard coded some where or I'm not using the right property name in the web.config. I copied the web.config value straight from the example in the documentation that came with the MySQL .net connector.

Why does a very simple script which inserts 26,000 records into a mysql database (myisam, no transactions) take 13 seconds in the php implementation, and then 35-50 seconds using mono+mysql connector? I thought asp.net was faster than php? Could the problem be the mono mysql connector is "platform independent", so the performance just stinks? or does asp.net suffer more overhead than php when it comes to executing each query? Aren't there any native linux binaries for mysql connector for mono that may be faster?

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.

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'm building an online file management system for a certain workflow. One of the services of this system should be as follows:
whenever a fax is received, it should be saved in a certain table in the database as a PDF file.
I'm using ASP.NET with C# ..
Is it possible to perform that task without the need for a middle desktop application?

I come from a coldfusion background, where setting up a connection to a database (Oracle, MYSQL SQL Server etc) was was easy as filling in a few fields in the datasource screen in the Coldfusion Administrator web app.
Then in the web application to connect to the database I would use <CFQUERY datasource="oracledb" name="test"> and in the body of the application I would write my SQL query and display the results of this query in a <CFOUTPUT>#variablename#</cfoutput> block of code, or to insert data into a db table I would use the
<CFQUERY datasource="oracledb" name="insertdata">
INSERT INTO table (columnname, columnname2, columnname3)
VALUES (
<cfqueryparam cfsqltype="cf_sql_number" value="#columnname#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#columnname2#">,
<cfif isdefined("file.serverFile")>'#file.serverFile#'<cfelse>NULL</cfif>,
</cfquery>
How does this process work in .NET? as I have to create a simple web application/form where on submission of the form the data would be stored in a MYSQL database.
what I have seen so far it seems a far more long winded and complicated process with .NET over Coldfusion with ultimately the same result, and I am desperately trying to understand how it works in .NET as surely it must be a similar process to that of Coldfusion?

I have developed a web application in asp.net with C# in visual Studio 2005. And i used sql server 2008 as back end. When i run the program, it shows the following error..An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

I'm trying to learn how to do both of them at the same time on my own, while working on a project. All the examples in the MSDN are using databases that are a local SQL Server (Express) file. I am not going to be able to just upload the project (including the file) and have it work, am I? The thing is - I want to be able to write code vs. a database that is actually going to work online so I can start putting a project together and know that it is going to work online.
I don't want to get everything done, and then discover it breaks as soon as I upload everything. Assuming I can't just upload the database file and have it work - I have a hosting account that I am using for something else and I would like to set up a database to use (preferably MySQL because my SQL Server database quota is used up and I'd have to pay extra for another, but I will if I have to because it's not that much). I can do that, correct?

I have never used reporting services before. My boss just started teaching me how to use them. I was told something by my boss that I find hard to believe. In our environment we have 3 databases: Development Beta Production According to my boss, the connection string has to be hard coded in the reports. Therefore every time you move a report from one environment to another you have to manually change the connection string so that it points to the correct database.

Here is the developer resource for the API I am looking to work with:

Further, my systems are currently in ASP/ASP.NET & SQL, and I'm familiar with VB so I would rather stay that direction instead of C#.
