I'm trying to run a GT.M database server in such way that It can be accessed from an application server. I know I can invoke GT.M as a sub-process from other languages. I'm trying to see if I can connect that to a socket/port to be accessed from another server, similar to other database connections(ODBC, MongoDB, Cache).
Are there any utilities? Libraries? to accomplish this. I'm more interested in a mechanistic overview.
The answer is yes, and you have many ways of doing it:
You can run GTCM, part of GT.M. I don't use it, so I don't know much about it, but David Wicksell built it into the Node.js binding to GT.M. More info here: http://tinco.pair.com/bhaskar/gtm/doc/books/ao/UNIX_manual/ch13s02.html and https://github.com/dlwicksell/nodem. Incidentally, you can use Node.js using David's node module.
You can run an M web server: https://github.com/shabiel/M-Web-Server. Look at the documentation folder for examples. Downside is that you have to write some M code (if you don't know M already). This is intended to be used as a web services platform.

Have a look at the below link, using this python module you can connect to the DB:

I have a client who wants a control panel for the app I am developing them. The control panel is a Mac OSX application that allows the user to submit files (excel docs and such) to my MySQL database. Those files are then checked by the iOS app I have created for them.
I have no idea how to do this. I have the MySQL database all set up, and I have looked everywhere for a solution. Any help is appreciated.
I wouldn't try to connect to your MySQL database directly from your cell phone. It's a bad design for several reasons. Instead build a API on the same server as the MySQL database. It doesn't matter if you do it in java, php, c# or anything else. You might even find some product or open source project that can do this automatically. I've listed some benefits of doing it this way
It makes testing easier. You can write a test framework against your API that doesn't rely on or is using a phone.
It makes development faster. You don't need to emulate or use a phone to develop and test your table design and queries.
It gives you compatibility. When you need to change your database (and you do) you can create new APIs that the new version of the app uses while and old version still out there can continue to use the old API (that you might have to modify to still provide the same functionallity)
It gives you flexibility. If your user base grows and you might need to have replication for reads or sharded databases you build that into the API instead of into the app which is just a better way to do it.
One option would be to use PHP to handle all the database interaction.
Host the scripts on the server and just have the apps call them and get the scripts to return some sort of parseable response (I'd go for JSON).
I have never found a suitable Object-C based connector for MySQL. At this point I would suggest using a C/C++ connector. There's lots of examples of how to configure the connector for both C and C++. The hard part will be all of the data passed from the MySQL code and the Object-C code will that it will have to be in C types.
EDIT: An Example
Back in the MSSQL 2000 timeline, there was an IIS integration layer that allowed HTTP GET commands to make select statements, and there were other SqlXml niceties that worked (not that fast or well but they worked) out of the box. I gave a chance to expose database stuff fairly quickly.
What is the comparable technology for MSSQL 2008/2012? I saw slashDb (http://www.slashdb.com/) and it seems to do that, but I am trying to understand the other options out there. Just SQL Server crud and sproc access.
Thanks.
Yes, SlashDB does exactly that and more. Full disclosure: I am the founder and CEO.
Once SlashDB is installed you would use its web interface to connect it with your database. Depending which database login and database schema you use for that connection, you will have the tables and views from that schema turned into of URL endpoints.
Those URLs can be followed in the browser but they are also API endpoints in JSON, XML or CSV. It works for reading and writing (you can control that in user configuration).
In addition to that you can define a set of parameterized SQL queries. Each query is given a name and instantly becomes an API endpoint too.
In order to help you getting started easily SlashDB is available on AWS and Azure marketplaces, as a Docker container from DockerHub, pre-built virtual machines or as .rpm and .deb packages for installation directly on Linux.
For more technical info please visit: https://docs.slashdb.com
The nearest equivalent may be SOAP/HTTP endpoints, however Microsoft has deprecated them for various reasons and recommends WCF or ASP.NET instead. Although the simplest way to get a quick CRUD setup is probably to use a framework or ORM that generates it for you, like LINQ to SQL or whatever else suits your needs.
I am trying to configure Apache2 so I can use MySQL for authenticating users to access certain pages. Also authorization needs to work so different groups can reach differen pages.
Now, I have googled a lot but can't find out how to do this. At least not for the configuration I am having. There doesn't seem to be any version of mod_auth_mysql that supports my configuration.
OSX 10.6.4
Apache 2.2
Now, how do I achieve this not creating my own login-application in php but using the built in support of Apache2? I'm totally stuck on this one...
Thanks in advance!
Regards,
Niklas
I also would like to use a taylormade login page, not pop-up

Short answer is that you can't. Unless you rewrite the Apache source code or create your own module, you can't mix HTTP based authentication with non-pop-up login prompts.
However if you are using PHP then a relatively low impact solution would be to use auto-prepend to prefix every protected page with a check on the users session. Obviously this would need a bit more thought if it is to be applied to files other than PHP source files (it'll work perfectly well if you tell Apache to apply the php engine to, say .gif files, but your script will need to detect and return the appropriate mime type).
A simpler solution might be to put a tool like squid in front of the webserver as a reverse proxy, then make the session handling data available to the squid url-rewriter.
You can build mod_auth_mysql from the source. Have a look at this post.
I you want your own log-in page, you cannot use Apache to do authentication.
Apache authentication uses the Authentication portion of the HTTP standard, and as a result you're reliant on the browser to handle the interaction with the user. There are plugins (like mod_auth_mysql) to use a database as the backend for this, but Apache can't ask the user for their credentials any other way.
The fastest approach might well be to set up Drupal or Joomla, which will get you user and group management as well as full content editing, in a way that will let you control who can edit what.
G'Day,
I want to use the Windows API Postmessage() call from inside a MySQL UDF on MySQL 5.1.51 (XP SP3). I know the UDF (Written in Delphi 2006) is working by setting a bogus result for the UDF.
The syntax of the UDF takes two integer params, one for a window handle and the other for a message number. However a call to PostMessage() from inside my UDF causes an exception in mysqld and the service stops.
Any ideas or pointers? Alternatively if anyone can tell me how I am able to simulate IB Events for MySQL via AnyDAC and Delphi OR an alternate approach to getting a notification when a record has changed in the database then please show me the light.

Your going to run into problems with this approach mainly due to the fact that messaging will only work to the same access level, and within the same session on the same computer. You would be better served by using other methods, such as TCPIP sockets, MailSlots, Memory mapped files, ect.
To best simulate a post message, I would use TCPIP UDP. A good lightweight library that I have used in the past is Synapse. The synapse library from SVN does run quite well against the latest versions of Delphi. The class you will want to use for this is the TUDPBlockSocket.
As an alternative to windows messages or TCP/IP, you might want to consider the named pipes answer to this question on sending information between two Delphi programs and this question on what named pipes are.

While I have had success via the UDF / Windows Pipe route I had another idea leveraging off being able to tap into the information message framework(?) in MySQL. See https://stackoverflow.com/q/3992779/223742
I am really confused on how to get data in and out of an android app from the internet.
I imagined that I would store information in the mysql db on the server I already have set up. But from what I have read, I would need some type of in-between web service to make queries with data sent from the app.
Can anybody toss me some tips on how to get something like this started.
Or, if you know of a better way, let me know about it.
This question has been asked several times, for example here: How to get from a MySql server to an Android app?.
Bottom line - you don't connect directly. You have something on your server (like RESTful) that you connect with via HTTP.
Try this method out. I will be using this method for the current project i am working on.
You basically create a php script on a server and use http posts to send the data to the script, read the tutorial linked below for better explanation.
