Re: sql copy does not work

You probably need to add escaped slashes into your perl string to escape
the quotes on the command line. Maybe try:

system ("su - postgres -c \"echo \"\\\"\"copy test from
\'/data/log/20060115.out\'\;\"\\\"\" | psql imsdb\"");

Subject: [ADMIN] sql copy does not work

Hi

I have a problem with the copy command. I need to write a Perl script
where I copy the log files into the database.
If I use the copy following syntax in shell script it works, but I need
to use it in Perl.

In shell script look like this and it works.
su - postgres -c "echo "\""copy test from '/data/20060227.out';"\"" |
psql imsdb"

this is how it looks like in Perl:
system ("su - postgres -c \"echo \"\"\"copy test from
\'/data/log/20060115.out\'\;\"\"\" | psql imsdb\"");

I escape always the " but then I get the following error.
copy
sh: | psql imsdb: not found

If I try the other way around there is always an error that role c does
not exist....
system ("su - postgres -c \"psql imsdb -c \"copy mss6n from
'/data/20060227.out'\;\"");
psql: warning: extra command-line argument "copy" ignored
psql: FATAL: role "-c" does not exist

If I try to use copy with the -c option I always get an error that role
-c does not exist.
Anyone has any idea why?
I was searching in the knowledge database and docs for this error but I
can not find anything.

Many thanks
Aniko
