Another user asked the similar question, What are the query browsers for DB2?.
But I would like to ask: what are some SQL browsers with a graphical query designer? Like the other user, I'm also using DB2, but most generic or open-source clients can connect to any SQL server, so I'll assume if there are any with a GQD, I'll be able to use it with DB2.
The vintage of our DB2 server and AS400 is v5/v6 and unlikely to be upgraded any time soon, and I find the included IBM SQL client to be primitive to the point of useless. The other clients I've tried are DBeaver, Toad, and Squirrel. I got DBeaver to work with our server, but other two I could not (yet). It's very nice and I'm happy to stick with it, but alas it does not have a GQD.
I understand many DBAs feel a GQD is an impediment to advanced query design, and I agree. However, it can be a useful tool for visualizing and building sub-sections of large queries, especially joins and weird logic. I find the most useful method is to design some or all of a query graphically, and then switch to pure SQL and clean it up.
Check out AQT Advanced Query Tool
It has a graphical query builder and can be recommended - it supports Db2 for iSeries

I'm looking for the best sql client to use with AWS Athena (with JDBC driver).
One of my needs is to share the queries between users, and I would like to know how can I do it in the best way.
The options I see are:
Using the web Athena query editor, and save the queries in 'Saved Queries' tab. Generally I prefer to work with a DB software, and not this web tool.
Using a simple DB client tool (I use DBeaver right now), and share the queries using git. (I find it uncomfortable, because the user will need to choose queries based only on their name, and it might get tricky when there are a lot of queries)
Is there a better way to do it? for example an SQL client that imports the Athena saved queries
Also- I would be interested to find a way and generalize my SQL queries - for example, to edit values in them without changing the query itself. I guess it can be done using some scripting mechanism over the SQL or the DB itself. Any idea how to do this with the client too?...
Thanks!

Do you know any free tool which would constitute a web-based SQL database generic query interface, incl.:
(mainly) allowing to type in an SQL query and display the result in some nice way
the interface should allow for some basic security - allowing only SELECT queries
the very need is to support MS SQL Server, but Oracle support would be useful
should run against an existing database instance without any re-configuration needed
might be simple, no need to browse tables, analyze database columns or anything else you would experience in SQLDeveloper or SQL Server Management Studio
Platform / language / etc. is of second importance.
The StackExchange Data Explorer has this functionality (example) and it is open source, so you may be able to just install and make use of it, or even extract the relevant code.
Perhaps something like the SQL Fiddle?
Obviously, this is mainly for demonstration purposes - it won't help you if you want to install it on top of your own database.
Re:dash (Redash) is a promising new open-source player on the market. From their own website:
re:dash is our take on freeing the data within our company in a way
that will better fit our culture and usage patterns.
Prior to re:dash, we tried to use traditional BI suites and discovered
a set of bloated, technically challenged and slow tools/flows. What we
were looking for was a more hacker'ish way to look at data, so we
built one.

Yesterday I read an article in PowerTimes ( dec. 2002 :) ) about a great SQL Optimization tool called SQL Expert created by Leccotech. This company is probably taken over by Quest Software and I faced a lot of bugs in the trial version of Quest SQL Optimizer 8.0.0.
Which software do you prefer to optimize your Oracle ( 10 or 11 ) SQL queries?
Regards,
Marinus
I too use explain plan (and a decent grasp on Oracle Concepts and the optimizer), but I'll also mention that Oracle develops a SQL Developer IDE that is getting more advanced than when I first used it.
SQL Developer now has a SQL tuning advisor that is worth checking out. I have not yet used the latest version, but will be doing so soon.
Hope it helps.
I use EXPLAIN PLAN with the SQL client of my choice
I also use the explain plan.
The best method to tune a query is to know as much about what it's purpose is and what it is doing.
Learn about the tables, indexes, constraints, data most importantly, and how the CBO (or RBO) is going to retrieve the data.
You can use software to point and click your way through, but if you don't know yourself what the query and oracle is doing, you won't get very far.

I'm looking for some freeware Query Builder.
Query Builder in Aqua Data Studio allows you to visually build queries:
select the column you want returned
generates joins for you(you just select by which columns you want to join it)
Good question! I thought there were many DB tools that fit your description, but when I checked a commonly-sourced Wikipedia article (see comment below), I found that most free/open source DB management software does not have a visual query builder feature! (I build my queries from scratch, so this is not a feature I particularly need.)
The freeware version of Toad for Data Analysts is a good bet. You can download and use it for 120 days. After that time, you need to reinstall on your PC. You might need to check to see if you will get write-access to non-Oracle databases, but I do know you can at least get read access to most non-Oracle DBs.
You might also like SQL Developer, which has a more robust community of users than that of the Freeware Toad for Data Analysts. That will only give you read-only access to certain non-Oracle databases.

I am a code developer, not a DBA, and I tend to get lost with loooong SQL queries, when I use many joins (10 joins is pretty common for me).
I would like to find a Visual SQL Query Builder (free if possible) that could connect to Oracle and see all the tables there, so I would only select visually my keys that link the Joins, and select the fields I want to be shown.
Oracle's own SQL Developer (free to download Java app) has a visual query builder (I haven't used it though, so this is not a recommendation, merely an FYI).
More about Oracle SQL Developer (and download link) here.
It is not free, but I use pl sql developer
http://www.allroundautomations.com/plsqldev.html
use Visual Studio Server Explorer to connect to oracle and then build queries using query builder.
Try Insight Developer for Oracle, but note that it is not free. I use it on both Mac and Linux.
Try SQLeo Visual Query Builder
http://sourceforge.net/projects/sqleo/
It permits to join tables visually
