Answer / nilesh

hi all,

This will also work fine, try it

select top 1 * from (select top 2 * from table_name)as set
order by set.col_name desc

here table_name is the name of the table from which
you want to retrive the record.
And col_name is the column name by which you are sorting
the records

If it found wrong plz correct it....
and show it on this site

Hi All, I am new to both this blog and technology. I was able to see a response for one of the questions on triggers as below. I would like to know why are we using " if rtrim(to_char(sysdate,'day'))=rtrim('sunday') then" instead, can't we use " if sysdate = 'sunday' then". I can understand the use of "rtrim", but dont know y v r using to_char. I have seen this in many cases but did not get a convincible explaination. Please help me with this and do excuse if this question sounds silly. Thanks in advance...... create or replace trigger trg_sun before insert on <table name> begin if rtrim(to_char(sysdate,'day'))=rtrim('sunday') then raise_application_error(-20345,'no transaction in sunday'); end if; end trg_sun;
