Hi everybody,
I have a problem with getting a table's name from a
variable.
example:
create function check_date(int4) returns date as '
declare
my_date date ;
my_tablename text ;
begin
select tname into my_tablename from tw where id = $1 ;
select max(idate) into my_date from my_tablename where id = $1 ;
return(my_date);
end;
' language 'plpgsql';
in the second select-query 'my_tablename' should give the (result-)
tablename
from the first query. How can this be done with postgres?
a friend has shown me the following with oracle:
select .... from &var ;
is this possible with postgres too?
greetings+thanks,
Thomas
