Hi,
How to redirect the output of an sql command to a file?
Thanks in advance
within psql you can use \o <filename>, from the shell you can use this:
[EMAIL PROTECTED]:~$ echo "select now()" | psql test > now.txt
[EMAIL PROTECTED]:~$ cat now.txt
now

This is similar to Andreas' solution, and which we use in our shell scripts:
[EMAIL PROTECTED] ~]$ psql mydb -c "SELECT cola, colb, description FROM
myfile;" > myOutFile.txt
If the sql string contains multiple commands, they will be executed
within a single transaction, unless you use BEGIN/COMMIT within it to
split it up into multiple transactions.
