“SQL ERROR: Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression”
My general principle is that a Trigger should be written to operate on a set of records, no matter what the primary use case is. A corollary is that, in the case where the Trigger must be restricted to a single record, that it should validate that it only has one record, or raise a meaningful error when there are more. And do not forget there can be no records!

This month of poetry is ending more with a whimper than a bang, but The Road Not Taken by Robert Frost still seems like a fitting poem on which to end. This exercise is clearly not on my beaten path, but I have enjoyed it and gotten some good feedback.
Putting these together made me think about other aspects of oral tradition. Punch lines of jokes and movie quotes are often part of a team's culture at work. Many of the better organizations have shared stories, of adversity, success, or special behaviors. One of my employers had a number of corporate stories that helped focus my efforts.
Think about the poems that influence your life. Ones that make you happy, help you to weather tough times, or remind you of special people.
If you applauded today's title, then I must quote Karnak, "May a weird holyman recite dirty limmericks to your sister."

Today's poem is the famous Trees by Joyce Kilmer. This poem possibly understates the grandeur and beauty of trees -- particularly the larger and older ones. This poem has always struck me as something that should be sung like a minstral tune.
As a kid I climbed my fair share of trees. In the last few years, I've heard of Recreational tree climbing and thought I'd like to give it a try. It has not seemed to caught on in Texas, but I might get a chance when visiting Georgia.

We could not have a National Poetry Month without including The Raven by Edgar Allan Poe. It is one of his most famous works and often studied in schools for its imagery and alliteration. Even young kids can enjoy a little scare from this poem.
During my 90's poetry kick this is one I committed to memory, for a number of reasons. I even goaded my cube-mate (we stared at each other all day) to learn it with me. We often started our day with a recitation and discussed unfamiliar words or the meaning of a stanza. The line "Respite, respite and nepenthe" has come in handy in a crossword puzzle or two.
I had forgotten that we studied this in school, until I remembered my teacher's antics. After reading a very dramatic and ominous "Nevermore" he said, "Actually, it was probably more like 'Nevermore, nevermore'" adopting a Polly Parrot voice.

Today's poem is another selection from "A Children's Garden of Verses", Where Go the Boats by Robert Louis Stevenson. This poem makes me think of my favorite "Curious George" book where he folds newspapers into boats. I read the book and folded a paper for each of my daughter's classes as "mother reader".
Here is a fun link with Bullwinkle reciting the poem, with just a few problems.

Today's poem was also shared with me, by a colleague, back in 1998. It is a piece of ancient Chinese poetry called Drinking Alone with the Moon by Li Bai. She learned it as part of applying to school in mainland China. It provided a differentiator besides grades and test scores.
The third and fourth lines --
Till, raising my cup, I asked the bright moon
To bring me my shadow and make us three.
