If been using "dbForge Query Builder" lately and I'm gotten used to the ease of building and testing a query, specially for those complex ones with inner joins, aliases and multiple conditionals.
The expiry date of the trial is about to come, and while wanting to remain on the legal side for this I'd rather not pay the 50USD it costs (although I must say it's pretty cheap for what it does).
So my question would be: Are there any free alternatives to replace this visual query builder? I've failed to find any and fear that my only two options are paying for it, or going to the dark side.
You may try FlySpeed SQL Query. It has the same powerful visual query builder and it's free if you don't need data export and printing.
You should try SQLyog, it has powerful visual query builder. It is very easy and intuitive to use.
I have found SQLeo, which I will use to show my colleagues how to build SQL queries. It is Java-based, so it will run on virtually any platform.
You will also need to install MySQL's Java Connector for SQLeo to be able to connect.
Think of it in terms of how much money/time it will help you make/save in the long run. Consider it a business expense. Yes, there are other free query builders out there, but they all take time to learn/get used to. If your happy with this one I'd say go for it.
That aside there generally are several ways you can reinstall the program and get one more month out of your free-trial if your still not quite sure its worth it.
Try EasyQueryBuilder.
It requires some configuration for your database at start but after that it's very easy to build queries with this tool - even for non-experienced users.
dbForge has an express version for MySQL that is free. I use the express version for MSSQL all the time.
EASY QUERY BUILDER is anything but easy if you're using MYSQL. Building a connection is impossible and their documentation is nonexistent. Don't waste your time.

I'm trying to retrieve a couple of webpages so that I can manipulate their information. I am looking for what are the best tools and packages for doing this. Preferably, I would appreciate to use Perl for parsing the tables, but I would be fine with using MySQL too, though I would have to learn it.
(I believe they are HTML tables, despite the page being coded in Java?).
I am not asking for any code, but for your opinion, tips and suggestions on how I can accomplish this. My intentions are, for now, to just parse the tables, merge them, and build a single table that has the information from both sites in different columns. This general table would only need to be updated once a day at most.
The tables can be found in here, please scroll down and in here, the full table.
Thank you in advance for all the help!
For web page retrieve, you can use the Web::Scraper, HTML::DOM, and also the LWP related modules.
And for SQL, the DBI module is very powerful. You can search these using the cpan.
Your question seems to be how to do webscraping. I don't see how MySQL would come into play with this. For webscrapint I suggest that you look at the CPAN modules WWW::Mechanize and HTML::TableExtractor

I have a relatively large MySQL database (over 300 tables) which I desperately need to convert to PostgreSQL and synchronise data between the two databases if not real time then something close to it. Ideally I need a bi-directional data sync, or at least one directional - MySQL to Postgres sync.
I have managed to convert the database and import the data, but synchronisation seems to be a real problem.
This solution from DBConvert should supposedly do exactly that. After many days of trying to make it work I gave up. They don't even have a linux client which is strange considering that absolute majority of MySQL and Postgres database would run on linux servers.
Is there an alternative to DBConvert's solution that would do the same?
Check out Pentaho ETL tools Kettle and its client interface, Spoon. http://kettle.pentaho.com
boy, you have a job ahead of you in terms of bidirectional synchronization. This is hard on the best of days, and it poses a lot of problems.
The tool I would look at first, actually, would be RubyRep. This gives you a basic framework for replication between your databases, and it supports a number of RDBMS's.
The second thing you have to think about is what you are actually doing and why this is a really bad idea. Your biggest issue is conflict resolution and managing what happens if two different people update the same record on the different db's. This is not a trivial problem and it requires thinking through the actual workflows and scenarios carefully.

I know my question sounds a little bit like a shopping request, but I honestly believe that many people could find it useful.
I've been looking for an automatic tool that converts Data Definition Language from MySQL dialect to Oracle dialect - the other way round would also be fine. I found “SQL Fairy” but I was unable to run it; probably because I'm not familiar with PERL.
Is there any free tool for Windows that converts MySQL DDL to Oracle DDL?
This site really worked for me and it can convert a bunch of different DDL commands from Oracle, MySql, M$ Sql Server, Sybase and others. http://www.sqlines.com/online.
Please note the disclaimer below the tool:
Note. SQLines Online is a unrestricted version for EVALUATION USE ONLY. For use in projects, please obtain a license.
Oracle has web pages filled with information on this: Database Migration Technology which gives detailed instrctions and help for several different databases including MySql.
The main tool referenced: Oracle SQL Developer is free.

I usually use MySQL Query Browser for my queries, but I always run into issues with the connections timing out and the Query Browser locking up, so I'm looking into alternatives. The new MySQL Workbench is much too slow and heavyweight, I prefer that the Administrative tools and the Query tools are separate (although it wouldn't be as much of a problem if the application wasn't so slow). I run on Ubuntu 10.04 x64. I'd like to avoid Windows/Wine-based solutions as much as possible. I also have had bad experiences (slow, buggy) with JVM-based MySQL applications, although perhaps other people know more lightweight ones.
I want something lightweight that can show me the schemas, tables, and column tree, and present a decent UI for editing tables.
Any suggestions would be appreciated.
I realize you want to avoid wine, but this might be a good suggestion for you as a free tool.
http://www.heidisql.com/
Although it does run on Java and may not be the prettiest thing ever, I pretty much always use Squirrel SQL client. If you haven't tried it, I recommend looking at it.
Squirrel SQL Client
+1 for HeidiSQL. On Arch Linux very easy to install. Get tarball from AUR;
Extract tarball to a directory.
In that directory: makepkg -s
After building package, install it with: pacman -U packagename
It works perfectly with wine. After trying some sql editors (Oracle SQL Developer, DBVisualizer, MySql Workbench) this was the best choice for me. Lightweigth & fast.

Are there any Open Source alternatives to Crystal Reports?
JasperReports if you're writing Java.
The java standard answer is often:
JasperReports: http://jasperforge.org
iReport: http://ireport.sourceforge.net
openreports: http://oreports.com/
Report Manager has been around for quite a few years. It's written in Delphi (at least it was originally) and has components that can be used in Delphi, but is usable via ActiveX or dll from just about any language. Now has a native .NET library too. Has a nifty report-serving webserver you can set up too. The designer gui looks and feels a little rough around the edges but it works.
http://reportman.sourceforge.net/
BIRT works pretty well.
How about i-net Clear Reports (used to be i-net Crystal-Clear).
Though not free, you should also consider this low-cost, non-free, non-open-source reporting solution that can fully compete with Crystal Reports - and is Java-based.
I think it's even more cost efficient than "free ones". A small company may have to think closely about free things, but will then have to invest into manpower to find out how everything works and so on. Large companies will for sure subscribe to premium support services that cost a lot. See this article for reference
i-net Clear Reports has a very low price tag with great support for free and even better premium support via yearly subscriptions.
Disclosure: Yeah, I work for the company who built this, so I'm biased. But I honestly believe in what I just wrote.
So far based on my research JasperSoft has turned out promising open source reporting tool… Matter of fact I am currently working on a huge project wherein I have started converting and building reports using JasperReports/iReports…
Every reporting tool has its own learning curve. The support group from and for Jasper and the quality of response that I have gotten so far is good.
Again at the end of the day it all comes down to what your business / organization needs.
You can use jasper report.
iReport is a very effective tool to develop jasper reports.
It supports almost all the facilities provided by crystal report like formatting, grouping, creation of charts etc.
