Обсуждение: rowcount function in postgres???

Hi,
 
   I am using 8.1.0 postgres and trying to write a plpgsql block.  In that I am inserting a row.  I want to check to see if the row has been inserted or not.
 
  In oracle we can say like this
 
   begin
     insert into table_a values (1);
     if sql%rowcount > 0
     then
       dbms.output.put_line('rows inserted');
     else
       dbms.output.put_line('rows not inserted');
    end if;
end;
 
Is there something equal to sql%rowcount in postgres?   Please help.
 
Regards
skarthi

Maybe:

http://www.postgresql.org/docs/8.2/static/plpgsql-statements.html#PLPGSQL-STATEMENTS-SQL-ONEROW

you could simply write

insert into table_a values (1);
 if found then
       dbms.output.put_line('rows inserted');
 else
       dbms.output.put_line('rows not inserted');
  end if;


If you really need the number of records inserted (found will be true if at
least one record as affected), you can get that with

GET DIAGNOSTICS num_rows = ROW_COUNT;
and then do the if on the variable num_rows.

Hope that helps
