Once upon a nightmare query, while I pondered, weak and weary,

Over many a quaint and curious part of code,

While I nodded, nearly napping, suddenly there came a hacking,

Someone gently hacking, hacking at my network node.

"'Tis some colleague", I muttered, "knocking at my network node -

Only this," I did decode.

Ah, DISTINCT I remember, was the key word in that code,

And each separate statement in that fact, was the purpose of that hack,

Eagerly I wished the morrow; vainly I had sought to follow,

Another book I need to borrow - borrow for another data mining crack,

For the rare and faintly used, as a developer not amused,

And fear I couldn't keep on track.

And then there came the hacking, hacking louder than before,

"Sir", said I, "Or Madam, use the correct password I implore"

But the fact is that I was napping, and so gently they came a hacking,

That in my slumber, I was even dumber,

That scarce was sure it true - I opened wide the door,

And in stepped the hacker, where he remaineth evermore.

But before I could stutter, with heart a little flutter,

In there stepped the hacker, like Bill Gates in height and stature,

"No!" said I, "That will erase my database!"

Too late the command was entered, and my resignation would be tendered,

And the hacker, the little slacker,

Remaineth evermore.
