I'm wanting to do some reporting on data which I have an a PostgreSQL
table. For lack of anything better, I've decided to see if I can do it in
GNU awk. OK, using Perl with DBI might be a better idea, I'll grant you
that. Or maybe Python or Ruby (which I don't know). But out of shear
cussedness, I'm going to see what I can do in gawk. What I don't see is a
way to get the data out of PostgreSQL and into my awk program. Does anybody
know of a way to do this, short of "cheating" by using psql? Yes, I know
that I could do something like (BASH on Linux/Fedora 22 x86_64):
awk -f some-program.awk <(echo 'SELECT a, b, c, d FROM schema.table ORDER
BY a' | psql dbname)
What I was hoping for was a "Dynamic Extension" (dll) which would allow
"native" use of PostgreSQL, or may ODBC. But I haven't found any. Have I
missed anything? If I were to create such a beastie, would it be of any use
to others? I guess, in this, I'm wondering what "report writer" most are
using when psql just doesn't have sufficient capability.
Yeah, sometimes I'm just plain stupid & pig headed. But then it will be a
"leaning experience" (with associated scars, I'm sure).
