I recently developed a Java Application for a client with MySQL database. Now he wants to have ASP.NET website connected with the Java Application. I'm thinking of placing the database on a local server which would support both the desktop application and the website. What i want to know is, is it the good way to handle these kind of scenario or is there any standard method?

I have encountered this problem before on a few shared hosts but cant remember the fix. I have spent almost 2 days googling and I have even gone through 2 external hd's of backups of old projects and read the web.configs but I just cant put my find it and I dont think I am googling the correct terms...
I am using Mysql Connector/Net to store asp session state.
The mysql db is on the hosting server ( I have no mysql locally).
Opening a page locally creates a session in the db.
Opening a page on the host does not.
I have seen this issue before but was a long time ago and I have searched a few of the answered questions here but not too extensive, I'm sick of searching.
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?
View 1 RepliesMy code is to update a record if it already exists in database else insert as a new record. My code is as follows:

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)
let me know what does these access modifiers means.private shared vs public shared vs protected shared
View 5 Replies how I can correct an error. I've built the MVCMusicStore tutorial here:
http://mike-ciccone.com/Store/
The first time I visit the site and attempt a database connection I get this error:
Exception Details: System.Data.SqlClient.SqlException: CREATE DATABASE permission denied in database 'master'.
But when I refresh, it all works fine. I'm at a bit of a loss. I don't believe I'm attempting to create a database, but I realise that the error may not really have anything to do with that. This is hosted at GoDaddy shared hosting. The database was created and I used an SQL script to create the tables initially and populate the data. My connection string works as I can pull data from the database, but I do have
a feeling it will be a web.config setting that will correct this.

View 1 RepliesI'm looking for a way to access a Java API from both a Java console application and an ASP.Net application.In short my Java API exposes a series of methods for dealing with invoices. All of these methods are essentially commands e.g.

All methods will interact with the database. I had believed Web Services was going to be my means for interop. But I have since been made aware of Java Stored Procedures in Oracle.

View 1 RepliesI'm in the market for an ASP.NET host to start learning on and to host personal projects. I've noticed most of them provided both MySQL and MS SQL databases. However, usually they will only provided a couple MS SQL databases, but a large number (like 10) MySQL Databases. Can I use a MySQL database as a back end to a ASP.NET website? If so why would I want to pay extra to use MS SQL over MySQL?

I'm interesting in deploy the .net authentication system but with a little changes. The first thing is changing the database that it uses by default to MySQL database.I'm not wondering in how/what to change on the web.config rather how to get the scripts that build all the database that it need(tables and so..).
After that I'll expend the user profile, maybe the roles and that enough for my website.So how to do a full move to MySql DB?
