subscribe-nomail

Hallo, erverybody !

I am working with Postgresql 7.2 on cygwin !

I have this problem inside from Database with functions and inside from
JDBC....

A Example :

create or replace function copy_data (varchar,varchar) returns varchar
as '
declare
aurl ALIAS FOR $1;
adelim ALIAS FOR $2;
begin

-- nice its work very fine with static param ...
copy transimport from ''/home/usrer/imports/trans.txt'';

-- where default \t is fieldseparator don't work with params wy ?
copy transimport from aurl;

--very very cosmic not for use in copy
--aurl := ''''''/home/user/imports/trans.txt'''''';
--raise notice ''killer: %'',aurl;

return ''ok-master'';

end;
' language 'plpgsql';
