I used this following command to set a variable in psql:
\set data_dir '/source_code/lookup/data'
And then I tried to used that variable inside a \copy command like this:
\COPY mytable_lookup FROM :data_dir/mytable_lookup.txt delimiter '|'
I was expecting that ':data_dir' will be replaced by the value that was defined
earlier, but got this error
message:
:data_dir/mytable_lookup.txt: Invalid argument
I have a feeling it is considering the whole 'data_dir/mytable_lookup.txt' as a
variable name.
Is there anything in psql that is equivalent to shell script's ${var_name} to
denote the beginning and
end of a variable name?
Thanks.
