Android SQL Client

Hi All,
Does anyone know of a SQL client for Android? Just something for running basic queries when I need to check on a system and can't be arsed waiting for a computer to boot up. The databases I use are MS SQL Server.
I've searched about and can't find anything. I've also had a look at the dev docs for Android and it looks like it should be straight forward using the java.sql class but unfortunately Java isn't in my skill set at the moment and the day job & life in general doesn't leave me with much time to learn it.
If there isn't a program does anyone have any plans to write one ;-)
Cheers
Keith

Anyone ???

It'd be pretty darn insecure to open up your databases to use a remote client like that, why not just use something like phpmyadmin for it? It runs fine in the android browser and theres tons of alternatives that probably have iphone themes that would work great. Alternatively you could get debian set up and grab one of the hundreds of apps to do it in the repository

I need this as well. I'm constantly on SQL Enterprise Manager on my PC and when mobile, I have to teamviewer to my desktop and run queries there, which is such a torture.
I've bought RemoteDB, which I can't seem to get to work properly, I can't switch databases and the connection registry is very confusing.
Anybody?!

I'm also interested in this topic.
As far as opening your db's up to the internet, that's a bogus argument. Anyone remotely managing enterprise databases will be using a vpn tunnel, and not the open web.
Having an Android app to connect to Microsoft SQL and Oracle would be extremely helpful. I've been trying to figure out how to mod Oracle's SQLDeveloper to do just that but without any success so far.

SQL Client
Hi Guys
I looked for something like this for a while as well, and couldn't find anything that did what I wanted, so I made one myself
Key features I wanted are the following
Be able to connect directly to a db server. I used the jdts jdbc driver for Java to get this right
Be able to connect to any SQL Server db. I'll add support for Postgres and MySQL if this gains any popularity
List of all databases on the server (excluding system dbs) and allow you to quickly switch between them
List tables in the currently selected db, and generate Select statements for them
List stored procedures in the currently selected db, and pull the code for them so you can change it
Use a tabbed interface for the different sql queries, to allow you to run many queries at once
This is all done and works really well. Large queries take longer to run than they would on a pc, but they run nonetheless.
Let me know what you think, and feel free to suggest features. If enough people like it and use it, I'll bite the bullet and buy the developer so I can publish it on the Play store
I hope you enjoy it
ps. The installer is signed with the standard testing key, so you will need to go into your settings and allow applications from unknown sources
pps. I ask for internet access to get access to the network sockets, but dont actually connect to the internet.

I've downloaded it and played with it a bit - looks good. One feature I'd suggest off the top is storing the connection info. It's a pain having to enter the server address and username each time.

If you are still looking for a SQL client I had written one as well.
It should cover most of the popular databases and works well with tablets and phones.

so, this one does BOTH MySQL and MS SQL, and, your other one *just* MySQL ?
thanks, anyone

Correct. The pro version will handle MySQL, MS SQL, PostgreSQL, Sybase, and Oracle up to version 10.1.
The MySQL version is strictly MySQL.

thanks for reply (and for nice app!)
nice, looks good... even better, seems to work well....connected to remote MySQL OK
suggestion: please auto-suggest correct ports for relevant SQLs
so, editing can only be done via queries ? (time to learn SQL syntax..?)
next, I'll try connecting to MS SQL, whilst I know a tiny bit about MySQL, I know nothing about MS, might be asking for help...
Nic,
need some help, if you can:
having issues with MS SQL, MS SQL is on a cloud server, for all I know, port could be blocked..
I've setup definition with port 1433, get 'failed to connect'
how to t/s outside of the app ?
should "telnet host 1433 " work ?
I'm getting
# telnet mssql2008.xx.yy 1433
Trying 202.111.22.33...
telnet: connect to address 202.111.22.33: Connection timed out
what else can I try ?
thanks for any pointers!

Hinting a default port is a good idea. I will see about adding in an upcoming release.
Yes right now anything beyond a simple select or delete must be done with a custom query. My goal is to make it more like the desktop editors, but since I am the only developer it might take a while. But I am not saying it won't happen.
If telnet is failing to connect then there is a firewall rule blocking your IP. Three things could fix this.
1. Add your IP to the database allow list (talk to the DBA)
2. If you can connect to the network the DB is on via VPN then you should. The db might be restricted to local IP
3. Use the SSH features of SQLTool to connect to a server on the databases allow list
You were smart to try the telnet. I would have done the same thing.
Feel free to contact me here or through the tools site. I'm happy to help

Nice catch on the SQL Type. I will work to correct that.
For dump / backup are you referring to data or structure or both? Right now I have exporting DDL on my things to do list, but if you're referring to something else I'd like to hear it.
Thanks for the compliments on my app. I definitely want to hear more suggestions if you have them. Also please don't forget to rate well when you get a chance

J2ME web server, access localhost using IE

I am trying to make a program in j2me (using Esmertec JBed) that acts as a web server (that only serves the localhost) and calls a browser to connect to itself.
Sounds simple enough, but I can't get it to work.
I am using the web server code here:
http://javaswamy.blogspot.com/2003/09/j2me-turning-your-phone-into-web.html
and added
"platformRequest("http://localhost/");"
to the end of startApp()
There are 2 problems, though. The JVM cannot open the URL because apparently it cannot run opera while my code is running (it can't run 2 java programs at the same time?)
If I open IE and go to "localhost", I get "Action Canceled".
Anyone has experience with this?
If you are interested, I am trying to make an offline wikipedia reader. I don't want to lose all the formatting, and using the browser to render HTML sounds like the easy way to me (I can even implement links since it runs as the server). I will just write a program to convert all the wikitext to HTML on a PC, and somehow produce a database based on a wikipedia XML dump. There is no HTML renderer for j2me.
Many thanks!

Advice on the choice of querying a remote DB

Hello everyone,
I come to you for some advice about an application I'm developing for Android 1.6 and higher.
Specifically, this application must be able to query a remote MySQL database and display the retrieved data. It need also be able to UPDATE data on this databse and that is where things get complicated ...
For selection queries, I wrote a small PHP script on the remote server that retrieves the desired data in the database and encodes them in JSON. From my Android application, I have no problem to retrieve, process and display them.
Now I wonder about the solution (if there is one ...) to run UPDATE from my application on the remote database. For now, I see only two solutions:
- Develop a webService on the server with an update method. Several problems with that: it seems webServices on Android are not easy (not native, have to go through external libs). Moreover, as it's UPDATE query, I want to make sure nobody else can use this webService.
- Alternatively, write a PHP script that makes the UPDATE and call it via HTTP. Same problem as webService: I want to secure this call to be sure that only I can use this script. These scripts can be integrated into an application already present on my server and which is secured by login / password. So, if it is possible to manage PHP sessions from Android, it's won! but Ican't find anything about it ...
What do you think? Ideas?
Thx!

[IDEA/POLL] Use C2DM app for remote phone access

These apps allow you to remotely access your phone from a web browser. However, they all run a web server on the phone, and I cannot connect to any of the over 3g (Verizon).
LazyDroid Web Desktop
Remote Desktop
Remote Web Desktop
I want to move the web server off phone, and (hopefully) onto private sites.google.com site. App Engine might be necessary, but I'm hoping this could be done solely in JS.
The hosting site would provide the UI, and interact with the phone using C2DM (the magic that powers Chrome2Phone, GMail, and installing apps from the web Market).
The UI is pretty obvious. It just needs a whiz to create HTML, Javascript, etc.
The C2DM backend is a still a bit mystifying to me... and searching for c2dm and javascript does not yield any obvious working implementations. But it seems plausible. Push a command to the phone, phone returns/uploads data to website, and UI updates.
Then there is the Android end. Well, there are the 3 projects above, Tasker for a quasi-hackish approach, and RPC (promising, but it seems like a WIP).
Thoughts? Volunteers? Geniuses?

Ooo... 2 birds with one stone!
This would also kill 2 birds with one stone.
No more typing in dynamic IP addresses! You get to use DNS to handle the connections. Bookmark your site in your desktop browser (it is always the same!). And set a preference in the Android app.

On lazydroid i've in planning some kind of trick that will let you connect behind firewall ... similar to a vpn...

I tried it again last week, and it is still unsuccessful. Webkey is currently the only application that I can successfully use to reach my phone.
Now, I could be wrong, but I believe all of these apps run a web server on the phone. I get a lovely, private 10.x.x.x IP address, which I can't reverse the route to. I have tried and failed to get DynDNS to work.
I have been looking into a solution since my original post. I have not had any time to do code squat, but I have loosely figured out all of the parts.
The big architectural difference I have been seeking is removing the server from the phone. I am not an Android expert, but I don't believe it even requires a running service. (Thank you, C2DM.)
With the app-webservice separation, you can work a "protocol" that reduces the overall bandwidth used... and thus improve battery life. Put all the "hard work" on a webserver, and (things get fuzzy here) possibly push it off onto the client browser (JS).

C2DM Browser Links
I could probably make something like WebKey but with C2DM and some more features. If you want you can give suggestions and I'll start making on saturday (after my exams). It would probably be possible in javascript for the actual sending from server and php just for logging in to your google account. The phone would just be registered on the server and no services (just as you wanted )

I am not sure "more features" is necessarily the direction I'm headed. I am focused on making a "seamless" experience (i.e. less separation of phone and computer).
I was headed to App Engine (Python bias + easy Google integration). I have a project created. I haven't pulled together the various examples to make the core, but it seems <naive>simple</naive>. Stir in some templates, CSS, a sprinkling of JS, and voila!
The big "tricky" part that I can't convert from f***ing magic to a clear approach is the data link in the server. I want to avoid any storage to a Google disk, or otherwise, even temporarily. No stored data = easy privacy policy.
nebkat, if you're really chomping at the bit to code, here's my Android client concept.
- C2DM is a wake-up call. (cheat an borrow ChromeToPhone's ID to begin with)
- Connect to web server, send "I'm here," and wait for further instructions (Channels API/Comet/AJAX/.........)
- make the command set extensible
- each command is blockable in the client. (Permission control is set on the phone, not remotely.)
- After N minutes of no activity, send a "good bye," disconnect from the server, and fade into the background.

Don't worry, I'm very experienced with the server side stuff and I know exactly what you want. The only information stored on the sever side would be google account, the device c2dm registration id and some logging features just for statistics. A password could be set on the phone that would be sha512 hashed on the ajax request and would be sent to the phone. Even if a hacker found the hash, it would be useless without being logged in to the persons google account or knowing the server side auth token.
For now i'll just make the reciever, processor and command output and later on the extra security and ui stuff. It will work exactly the same way as Chrome2Phone except it will have server side php and the different commands. The connection from pc to phone will be something like this.
user command -> ajax request -> php c2dm request -> phone
phone -> php server http request -> controller page status
BTW I'm saving up for a Nexus S, how much would people pay for this type of app? There would definitely be a free version, but I just need to get the Nexus S because I have a Galaxy Spica now and it isn't the best for app development. I'm new to how stuff at xda works, would a donate version get me enoguh for the Nexus?

Alrighty then. I'm feeling like I can stop contemplating implementing this.

Since I was learning the ins and outs of App Engine, I read their quota rules and realized if this were popular it would require funding. I don't know where you are going to your web server, but I assume you'll have to pay someone to keep it running. But I had thought about $$$ already.
"Give away the razor, and sell them the blades."
Make the app free, no feature restrictions.
You get your money through various "membership" levels on the server. (See the account levels at fastmail.fm for an example.) So, you can use the app for free, but you only get, say, 2-3 MB of traffic per day, and only X sessions per day. Need more? See the pricing chart.

lather, rinse, repeat.
C2DM is not deterministic, and acts up in low signal conditions. So, I made a decision to only use C2DM to initiate a session. Once both ends are connected to the server, everything goes over HTTP.
Oh.... and not that we need another Lookout/Phone Finder, but a shared-secret SMS code for the case where "they" have shut down the data connection.

I have my own server nebkat.com and there is nothing on it anyway.
The only other way to make "push" requests to the phone is with WebSockets. It would probably be better than c2dm because we have full control over what gets sent (google limits some requests). The advantage of WebSockets is that they send no header information which means that we could send our messages in 20 to 30 bytes.
I'll look into more detail on friday.

With web sockets won't you need to ensure the phone has a routable, external IP address? I know, for one, t-mobile does not expose an external IP address for their phones. Unless, of course, if the phone is connected over WiFi. C2DM works great for me (I have used a couple of apps with it and it is really useful).

No, WS is server initiated and the ip address' shouldn't make a difference.

You need an valid external IP address if you are attempting to initiate contact with your phone, which is why the 4-5 apps I've mentioned do not work on carriers like t-mo and verizon.
But the phone can establish a connection, and the carrier NATs (or whatever) will handle the routing for outgoing and incoming data.
I think the right questions are: Will Verizon/T-Mo allow the ports and protocol for WebSockets? Do Android and desktop browsers implement the draft API correctly and consistently?
I like C2DM. I works well when you have a good connection. But there are 3 issues with it.
1) The message size limit is 1024 bytes. Not ideal for file transfers.
2) In a poor signal areas, since the service retries sending messages, you will get delayed and/or duplicate messages. I work in a large "concrete" building, so I get this behavior often enough that I don't want to rely on it.
3) I believe there is a limit on the number of messages you can send. So, hunting around the filesystem could hit this limit (but unlikely in reality... I hope.)
It would be interesting to see exactly how those apps handle all of the data. Do they only use C2DM, or do they hand over to another protocol?

Ok my exams are over and I am starting with it. I'll give updates on this thread

[Q] need help ,developing group messaging over WLAN

I am supposed to develop a group messaging app (IM client) using WLAN ,its a term project.This app is supposed to list all the available users that are connected over the wlan and provide the user with the options ,to create a group ,send group messages or send messages individually over the wlan.I have had experience of developing android apps in the past but none of them have ever been network based.
I need to know :
1.what Internet protocols will be used .(sip? ,voip?) for DNS etc ,yeah i have below meager networking knowledge.
2.what areas do i need to research any links to resources will be quite helpfull .
3.any open source app that offers the same functionality
4.do i need to set up a server aswell ?
I would be really thankfull for your advice on this .

Take a look at XMPP which is an extendable and open source messaging protocol.
DNS is just used to convert names to numbers, so you'd give your server a name and create a DNS A record, then the clients would use that name to locate the server. XMPP works over TCP/IP which is useful as it's implemented in every operating system I'm aware of. There are also XMPP clients (which is a protocol that works on top of TCP/IP) for all platforms out there as well.
Check wikipedia for XMPP to give you background information, then look at something like openfire as a server implementation, it's pretty simple to setup and has a web based configuration.
