I have a very limited understanding of databases and how to interact with them. At my place of work the Database Admins have servers running Microsoft SQL server 2005/2008.
I manage software that interacts with some of the databases on these servers which does so through an OBDC connection which I had to set up on the Application server.
However, I also sometimes view the tables on the databases using Microsoft sql server management studio 2005.

I'll log in using SQL server authentification rather than my windows credentials (as worryingly they actually let me have SA rights (well, the applications server needed SA to create the database, so I use that)).

Screenshot is a random google image
http://game-maps.net/staff/reborn/fig1.png

Then I'll browse to databases->the database I want->tables then I view the table...

http://game-maps.net/staff/reborn/fig2.gif

I set up an ODBC connection on my client PC and sometimes view the databases in Microsoft Access instead, as I find setting up views easier that way.

This is the entire extent of my database knowledge. I do know how to run SQL queries, but I do not actually know any SQL queries.

What the fuck has any of this rambling got to do with renegade modding?

I want to know how to create a plugin that will interact with a database. I need to know how to install the database server, which database server software most people use, and I need to know how to create my tables, access data, modify data, write data, compare "cells", close the connection properly, pretty much everything.

Is there anyone willing to help?

What would be really fucking awesome would be a tutorial using the SSGM plugin.
The tutorial would ideally include how to install the DB software, then proceed to demonstrate in the plugn how to connect to the database and handle errors (like the db doesnt exist), how to create the table and set up the headings (if they do not exist) via the plugin itself. Then how to write some data and read some data, and modify some data too.

What? You mean like:

SELECT/INSERT/UPDATE/DELETE etc.

The queries you need will also depend on the flavour of SQL used, for instance Oracle differs from the ANSI standard... although I doubt any Renegade server owners are running Oracle databases.

Most likely your going to want to support MySQL, since that's used by a lot of websites for their backend.

Yes, but I want to learn how to do this programatically.

Yes, that would be likely. Now be awesome and write that tutorial and example plugin! Very Happy

SQL 2k8.

I would use sql server authentication so that you can supply a DB username/password.

Btw I work for a software company that uses databases heavily with C#.

there has to be a C++ wrapper for this.

A totally awesome person would add that wrapper to a plugin and show a few slick moves using it! Very Happy

By the way, totally sorry for not sending that stuff out yet, no excuse for it really, just been at the back of my mind.

I am not really sure what the point of making an SSGM plugin to connect to a database is... other plugins are still going to have to make their own connections and run their own queries based on what data they want to store / retrieve from their own tables, so why have another plugin which just creates a random connection for no apparent purpose?

sqlite is the easiest thing to use in my opinion. (http://www.sqlite.org/sqlite-amalgamation-3070500.zip)

An example... It would show me what to do in simple terms, so that I could make my own and expand on it.

Thank you, I will start googling, I guess. Smile

If your interested in using SQLite you might want to look at the BRenBot source code, since that uses SQLite for it's database.

Of course, that's written in Perl... but you will be able to get pointers on the SQL side of things.

SQLite definately seems like the way to go, it's built into the application and you get the source code, no database server needed, it's just part of the app. Feeling it.
I just compiled a dummy plugin with the sqlite header file and .c file. Doesn't actually do anything yet, but it's nice to have it compile without errors and start diving in.
Looking through the site now.

I tried using the easysqlite wrapper for sqlite, it's got me up and running very quickly, and I have now successfully created a database, a table, and some records of different types. I was also able to read these records, modify them and print them to the console screen.

I'm extremely happy! Very Happy

This was only a small test, but you can see it clearly working in the screeny below. Modified scripts.dll using a database is nothing new, I know of at least Two people that have already done this and there are probably plenty more people that could if they wanted to.
For me though, this is new and exciting. It opens up the door to more possibilities.

Don't forget that SQlite can block your server.
Work with threads if you don't want horrible lags.


Bückstabü!

Indeed, I had considered that. I will make sure I use a thread for the database. Smile

Did you make any progress with this, Reborn? I'm gonna play around with SQLite soon and I wonder if you found any interesting/resourceful links or software libraries. WxSQLite3 is a wrapper that uses WxWidgets' data types, and YaRR also contains a wrapper for SQLite. I found a tutorial on the SQLite written in 2007. Haven't really searched for stuff though.

I found the easysqlite wrapper most easy to use. I never went anywhere with it though as the project I had in mind soon became boring to me. I actually didn't go much further than what I posted in this thread.

I am pretty sure that somewhere in these forums some source code was posted, by someone who used SQL in their build of SSGM, I'll do some looking and see what I can find. If I remember correctly they used it for their commander based system but looking at what they did could help you out a little.

Once again I'll do some looking around to see if I can find it.

I'd appreciate that.
