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. Syed This email is intended only for the individual or entity to which it is addressed.
