Parallel Hint

SELECT /*+ PARALLEL(a) */ COUNT(*) FROM ABCD a ;

Parallel Hint makes operation faster. It does so by providing more threads to the current SQL statement. Not advisable to run in Production Environment during Peak Hours.

When We are Joyful

WHEN WE ARE JOYFUL

 

When we are joyful, we don't look for perfection. If you are looking for perfection then you are not at the source of joy. Joy is the realization that there is no vacation from wisdom. The world appears imperfect on the surface but underneath, all is perfect. Perfection hides; imperfection shows off.

 

The wise will not stay on the surface but will probe into the depth. Things are not blurred; your vision is blurred. Infinite actions prevail in the wholeness of consciousness. And yet the consciousness remains perfect, untouched. As Satsangees, realize this now and be at Home.

Smart Choice for Cursor Processing

It's nice article desribing when to use
CURSOR FOR Loops
Avoid using it
SELECT INTO
Use when query can return atmost one row. Also put SELECT statements in seperate PROCEDURES/FUNCTION. Which can be optimized/cached in Oracle 11g.
CURSOR BULK COLLECT VARRAY [Fixed number of rows or less]
Use when SELECT query will return multiple rows but you know upper limit. If upper limit is very high say 10000, you may want to go for next approach. As it will consume lots of memory.
CURSOR BULK COLLECT NESTED ARRAY with LIMITS
Use when SELECT query will fetch multiple rows and you don't know the upper limit or you know the upper limit but it is very high.
