I am back developing futher our Python/CGI based web application run by
a Postgres DB
and as per usual I am having some issues. It Involves a lot of Legacy
code. All the actual
SQL Querys are stored in the .py files and run in the .cgi files. I
have the problem that I
need to construct a row from two seprate SQL Querys, I have tried
combining the two
Querys but all that does is create a Query that returns nothing after a
long period running.
the first query results are delimited with [] and the second with {} I
want my result to
return [ val1 ] [ val2 ] [ val3 ] [ val4 ] { valA } { valB }
unfortunatly when i put my second
query in anywhere on the page its crashes and returns a Internal Server
Error.
the functions from the cmi file are below.
