Sustainable Development

Science, education, youth
Are magical words to fulfil,
Advance, prosperity and welfare
Nothing grows from wishful thinking
Even plants grow from seeds.
Success, progress are a temper of the will
A vigour of the emotions.
There is in every being’s heart
The passion of excellence
But it’s covered with the snows
Of laziness and pessimism
Education needs to be watered
With hard work and perseverance,
But so long as you don’t keep watering
It will fade and wither like a waterless flower
Whether you are illiterate or ignorant
There is in every one’s life
The light of hope,
The love of learning,
The challenge of events,
Don’t miss your future because tomorrow
The truth will be dawned on you.

If he couldn't help him, he was going to die, and thus the tribe will die out. The leader sat by his fire, but he didn't feel warm.

It will soon be too late '' The leader began his journey that night. He walked through the snow and the dark forest all night. In the morning, he was cold and hungry. '' How can I find the medicine plants which will ...

NOCOPY Parameter Hint in PL/SQL

Before we get to understanding the NOCOPY parameter hint in PL/SQL, it would help to first look at PL/SQL parameter modes and the ways in which they pass values in and out of a subprogram. PL/SQL subprograms have three parameter modes: IN parameter mode is used to send values into the subprogram from the calling program. An IN parameter can only be read, its value cannot be modified inside the subprogram. OUT parameter mode is used to return values from the subprogram to the calling program. IN OUT parameter mode is a hybrid of IN and OUT. It is used to send values into the subprogram, and its value can be modified within the subprogram. On exit, the subprogram returns the updated value of the IN OUT parameter to the calling program. Continue reading at Source : NOCOPY Parameter Hint in PL/SQL
