Thread: Especial delimiters caracter

running the following script

select ('cabal\\' || user_name) into temporary user_access from
tbl_user_access where access_profile_id = 4;
copy user_access to '/temp/users.txt' delimiters '|';

The result of the output file is...
domain\\users
but the field in the temp table is...
domain\users

I need the same result like temp table. How could i do it??

$ cat fakedump.txt
C:\\Windows\\system32\\drivers|this\ttabbed\ttext\n
$ perl -p -e 's/\\\\/\\/g;' fakedump.txt
C:\Windows\system32\drivers|this\ttabbed\ttext\n

As you can see, this only handles \\ not \t=tab.
You could also do this in sed:
$ sed -e 's/\\\\/\\/g' fakedump.txt

Not really - it's designed that way so you can COPY TO a file on one machine 
and then COPY FROM on another.

$ cat fakedump.txt
C:\\Windows\\system32\\drivers|this\ttabbed\ttext\n
$ perl -p -e 's/\\\\/\\/g;' fakedump.txt
C:\Windows\system32\drivers|this\ttabbed\ttext\n

As you can see, this only handles \\ not \t=tab.

$ sed -e 's/\\\\/\\/g' fakedump.txt

No, you cannot. Because copy is also intended to work vice versa 
i.e. copy from file to table and therefore the doubled backslash 
is mandatory.
