When we are doing the frequent updates to the columns which
we built the index on the column then the index on that
column is non meaning ful because the index should rebuilt
every time the updation were happen.
we should create index on the columns which we use
frequently in the WHERE clause.
If we dont close the cursor also we do not get any error
the procedure will be executed succesfully but if we close
the cursor the private SQL work area allocated to the
cursor will be relased.
What is the main difference between a UNION statement and a
UNION ALL statement?
1. A UNION statement eliminates duplicate rows; a UNION
ALL statement includes duplicate rows.
2. A UNION statement can be used to combine any number of
queries; a UNION ALL statement can be used to combine a
maximum of two queries.
3. A UNION statement can only combine queries that have
parallel fields in the SELECT list; a UNION ALL statement
can combine queries with differing SELECT list structures.
4. A UNION statement cannot be used with aggregate
functions; a UNION ALL statement can be used with aggregate
functions.
5. There is no difference between the two statements; they
are interchangeable.
I have a small PL/SQL Block
assume in this way
begin
select * from emp where empno=100;
exception
when others then
<Some Messages>
when no_data_found then
<Some Messages>
when too_many_rows then
<Some Messages>
end;
The question which he asked was whether this block will get
executed normally or it will throw error ?
If errored out then what is the reason for the error ?
Could anybody please help me ?
