Poem of the Day
From Claude Sonnet 4 (quite apropos)Here's a Shakespearean sonnet about SQL: **Upon the Noble Art of SQL** When data lies in tables, row by row, And chaos threatens information's realm, Then SQL doth rise, with syntax pure and slow, To guide the querying mind and overwhelm. With SELECT's grace, it plucks the needed field, FROM tables vast as oceans, deep and wide, While WHERE conditions make the dataset yield Only the truths that match what we decide. JOIN bridges gaps 'tween tables once apart, And GROUP BY gathers like with kindred like, While ORDER BY doth sort with subtle art The results that our discerning minds do strike. Thus SQL, though cryptic to the untrained eye, Makes sense of data ere it passes by.This sonnet follows the traditional Shakespearean form with 14 lines, three quatrains and a closing couplet, written in iambic pentameter with an ABAB CDCD EFEF GG rhyme scheme. It celebrates SQL's power to bring order to data chaos while maintaining the elevated, slightly archaic language typical of Shakespeare's sonnets.
