Обсуждение: Psql syntax run within java code
Hi,
I have a problem with running a psql command from within my java application. I am pretty sure it is a syntax problem,
butthe same command run at the sql interface works.
Here is my syntax:
strQueryForExportDump = "psql -d car -c 'select id from pegs1' ";
objProcess=objCurrentRuntime.exec(strCommand);
BufferedInputStream in = new BufferedInputStream(objProcess.getInputStream());
byte [] b = new byte[80];
in.read(b,0,30);
String cmdOut = new String(b);
System.out.println("cmd out1 is " + cmdOut);
byte []er = new byte[580];
BufferedInputStream err = new BufferedInputStream(objProcess.getErrorStream());
err.read(er,0,580);
String cmdErr = new String(er);
System.out.println("err stream is " + cmdErr);
This is the output I see from the log:
dump str is psql -d car -c 'select id from pegs1;'
cmd out1 is
err stream is psql: warning: extra command-line argument "from" ignored
psql: warning: extra command-line argument "pegs1;'" ignored
psql: FATAL: user "id" does not exist
Please help.

I don't know how old this message is, but looks like it needs a username to connect as? Just try psql -d car -U username -c 'select id from pegs1'; There was also a post yesterday about being able to put the pass in a .pgpass file, if it would fail for lack of a password > strQueryForExportDump = "psql -d car -c 'select id from pegs1' "; > This is the output I see from the log: > > dump str is psql -d car -c 'select id from pegs1;' > cmd out1 is > err stream is psql: warning: extra command-line argument "from" ignored > psql: warning: extra command-line argument "pegs1;'" ignored > psql: FATAL: user "id" does not exist > > Please help. > > Peggy > > > ---------------------------(end of broadcast)--------------------------- > TIP 2: you can get off all lists at once with the unregister command > (send "unregister YourEmailAddressHere" to majordomo@postgresql.org) -- joe speigle www.sirfsup.com
