Visual query builder for PosgreSQL?
Hi,
I'm looking for some good visual query builder which can be used by
non-tech people for some ETL tasks. Do you have any recommendation?
Now, we're moving our data from Excel to PostgreSQL to deal with large
amount of data, and we need to process some ETL tasks, with using JOIN
and GROUP BY between tables, up to 10 tables on it.
Of course, I can write ad-hoc queries by myself. However, I'd like to
allow non-tech people to issue ad-hoc queries with using some visual
query builder.
I have already looked a query builder feature in pgAdminIII, but
I'm not sure whether I can use GROUP BY with it.
Do you have any experience or recommendation about visual query builder
for PostgreSQL?
Regards,

You can do joins in the PGAdmin3 query builder but I'm fairly sure you can't do group by's.
Apparently, SQL Manager from here:
http://www.sqlmanager.net/en/products/postgresql/manager/
Has a "Visual query builder allowing you to build complicated queries without any knowledge of SQL syntax"
I may be shot for even suggesting this (and it is a bit of a hassle) but you could recreate your table structure in MS Access and use its graphical query builder to generate your SQL. It does allow for group by's, counts, etc.

You should probably take a look at http://htsql.org/
It is free open source software intended for "accidental
programmers" -- people who want to pull summarized data from a
database without learning SQL or needing rigorous training. Its
development was partially funded by grants from foundations,
including the National Science Foundation. It does support
PostgreSQL and most definitely support counts, sums, etc. In fact,
it can automagically give you pretty summary graphs with the
ability to drill down to supporting detail.

I second this. I have been trying it out and it is proving quite useful.
The interesting part is that if you use the HTML interface you can get
the SQL sent to the server, helps you learn that also.

Libreoffice Base?
I know it has a visual query builder and it does support PostgreSQL, but
I have no clue what it is worth, since I tend to use SQL instead.
Sincerely,
Wolfgang

Correct. The pgAdmin3 graphical query builder doesn't support GROUP BY.

Thanks.
I have started trying "SQL Query for PostgreSQL" from EMS, the company
provides SQL Manager. I think "SQL Query" is the subset of the
SQL Manager, and would be suitable for our purpose.
(and a bit cheaper :)

Yeah, I will also look at MS Access as a query builder, although I'm not
familiar with the software so far.

Very interesting.
If non-tech people can learn a simple query language for their analytics
purpose, it would be worth trying.
I think some "abstraction layer" is needed between non-tech users
and DBMS to allow them to issue queries themselves.
I think some query builder could be one of the solutions, and
also some simple query language could be another solution.
I will look into it.

Many, many (many) years ago, while working at DIGITAL EQUIPMENT (before it bellied up), I worked with a relational DB they created called "RDB". Someone at DEC wrote an sql development gui in Xwindows called "InstantSQL". It was really great. All the tables of the DB were icons, you could drag the ones you wanted into the main workspace, open them up, graphically select the cols you wanted to "select" and join tables by click-dragging a line from one col of one table to another. You could build your predicate by dragging out search criteria boxes frmo the colmns, filling them in with the criteria, changing the logical operators, etc... . It supported aggregate functions, order by, and manual editing of the resulting SQL if you wanted to. The users LOVED that thing. They would build their queries, run them and redirect output to a file. Then "save" the query for future use. They would also use it to prototype sql which they would then cut/paste into scripts. Very intuitive to use and very user friendly.
Other guis allow you to do some simple things in a gui, like join tables, but I've yet to see something that let the user do it all in the gui. The single gui approach had some advantages, the most important of which (IMO) was ease of use and being so intuitive.
When Oracle "acquired" RDB, InstantSQL died with the DB (after the canabalized it). Haven't seen InstantSQL since. They're probably just sitting on the patent. I just wish good-ole InstantSQL was still out there. Your users, like mine of the past, would probably love it.

RDB/VMS was actually the first relational database I ever worked with.
Boy, is that a long time ago...

I have never seen InstantSQL itself, but I had chances several times
to go the RDB technical seminars here in Japan, where I have found
that learning database technology is really exciting. :)
So, I wish I will be able to work with RDB (and VMS) someday. :)

That most probably will never happen though.
Oracle has effectively killed RDB and HP has effectively killed VMS.
