View 11 RepliesI want to use MySQL as database server for my ASP.net website but don't know how can I write connection string for connecting database.
View 1 RepliesI have few questions regarding MySql database.
First one will be: I've installed MySql, Query broswer, and ODBC connector (not sure what this one does. Can anyone explain?)
Now, when im dragging a new DataGridView into the form, and try to connect it to a MySql database, i can't seem to find MySql in the databases list... why is that?
Second question, assuming everything works fine, how can i upload the database to a server and use it there?
I can think of two problems trying to do this : (1) Im not sure where my Database files are stored at... (for some reason, they are not found in MySql/Data... this folder is completly absent)
(2) While working with ACCESS, all i had to do is to point the .aspx page that did the connecting to the location of the .mdb file, but now, each time i want to reach my database, i need to send the page to the server (localhost). How will i create a connection to my database, when its on another server, in the code page ? (small code example would be nice).
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 RepliesI am trying to set up a server on my own pc to test programs i am making, however i keep running into an issue with Access databases saying that it's not registered on my local machine or something like that. So i was thinking of trying MySql instead, but i cant figure out how to set up a database to run on my pc. I have done it using MySql Workbench before to connect to a database set up on my schools server, but that was an already set up database that they created for each student. I want to know how to set one up on my own pc. how to set this up? I tried the server administration section of MySql Workbench but it seems to ask for an existing database already.

View 3 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?
