Using PostgreSQL 9.3 on Linux
I'm trying to extract data into a comma delimited format and not having
much success...seems to act totally different from Oracle. Does anyone
have any suggestions?
Just in case it helps you, I wrote a pair of very simple scripts, but
they have eased my life a lot:
* sql2csv:
https://github.com/pierrechtux/geolllibre/blob/master/sql2csv
sql2csv takes an SQL query as an argument, and spits out the result in
CSV. Just redirecting its output (>) makes a .csv file.
It is extremely trivial: just this is relevant:
echo "COPY ($1) TO stdout WITH CSV HEADER FORCE QUOTE *" | psql -X -h
$GLL_BD_HOST $GLL_BD_NAME
* csv2sql:
https://github.com/pierrechtux/geolllibre/blob/master/csv2sql
csv2sql works the other way: you give him a .csv file, and it dumps it
into your database, in a 'tmp_imports' schema (makes it easy for
cleaning...).
These utility scripts are very rough: all fields are considered as
strings (varchar), to be as generic as possible.
I use these 2 utilities in production daily, for a number of purposes,
including heavy diff'ing. So far, no worries, they proved to be very
reliable,
There are a couple of environment variables that should be just adapted
for a generic use: $GLL_BD_HOST and $GLL_BD_NAME.
My little 0.02€...
