How about this idea: A more general HTML report generation program, that
happens to come with a PSQL backend to start with (perhaps it should be write
in Java or PHP or something?) but isn't really Postgres specific, that allows
the user to set up a SELECT (just a text box will be fine, it's really tricky
to write a GUI for that kind of thing a la Access) then provide HTML snippets
for:
1) Header, including the <TABLE> element - defaults to
<HTML><HEAD><TITLE>$TITLE$</TITLE></HEAD><BODY><TABLE>
2) Start of column name row - defaults to <TR>
3) Column name cells - defaults to <TH>$HEADING$</TH>
4) End of column name row - defaults to </TR>
5) Start of data row - <TR>
6) Data cell - <TD>$DATA</TD>
7) End of data row - </TR>
8) Footer - </TABLE></BODY></HTML>
With time, it can be extended to:
1) Have a simple conditional thing so alternate rows can be coloured
differently to make the rows easier to follow, negative numbers can come out
in red, etc
2) Do some aggregration, like adding TOTAL, without having to do a seperate
SELECT SUM(foo) and stitch it into the table
3) Group by the primary sort key for a SORTed query, then producing a single
cell with a ROWSPAN for each distinct value of that field
4) Break the result into pages
5) Produce charts
etc...
Any takers?
