What a finished BU 453 Unit 5 single-table queries looks like
The submission is a numbered set of items, each built the same way. The question sits at the top in the assignment's own words, so a reader knows what the statement was aiming at before meeting it. The statement follows, laid out with its parts on separate lines so it can be read without running sideways off the page. Underneath comes the result, either the rows themselves or a stated count where the set runs long, captured from an actual run rather than written out from expectation. A closing line per item says what makes the result correct: which records the condition excluded, how rows with an empty value behaved, and what the ordering was chosen to reveal. No item turns its output into a business finding.
How a BU 453 Unit 5 example is structured
Each item leads with the question because a statement standing alone can only be checked for whether it runs, and running is not the criterion. Results are shown from a real execution, since a query nobody ran usually returns something other than what its writer pictured, and the distance between those two is where the credit is lost. The defending line comes last so the reader has both the statement and its output in view when the argument arrives. Items progress from a single condition toward combinations of filtering, ordering and limiting, which means a surprising result late in the set can be compared against the plainer ones above it. Columns that permit an empty value are addressed wherever a condition touches them, because a row that disappeared without comment is the defect this unit is built to surface.
The question written above the statement
Each item names what was asked before any code appears, since a statement on its own can only be judged on whether it executes.
Rows captured from an actual run
Output is pasted from execution rather than described from memory, because the difference between the two is precisely what the marker is checking.
One line saying why the rows are right
Every item closes by naming what the condition excluded, which separates a query that is correct from one that merely came back populated.
Empty values handled out loud
Any condition touching a column that allows no value states how those rows behaved, since a group lost in silence costs the item.
Items ordered from single to combined
Filtering comes before ordering and limiting, so an unexpected result further down can be read against the simpler items already established.
Where marks go in BU 453 Unit 5
Single-table queries lose points quietly. A statement that executes and returns rows looks finished, and if its condition excluded a group the question wanted counted, nothing on the page will say so. Output typed from expectation instead of pasted from a run is the usual form that failure takes. Items with no question above them leave a marker guessing what was being asked. Statements returning every column when the question named three read as untargeted. Conditions on a column that permits an empty value, written with no comment on those rows, drop the group the assignment planted there. Turning the output into a recommendation answers a different course. Practice queries run against a live company table are not schoolwork, however harmless the statement looks.

BU 453 Unit 5 questions, answered
Does formatting matter if the statement returns the right rows?
It matters more than students expect, because a marker has to read the statement to grade it. A single line running off the edge of the page hides the very structure being assessed, while parts set on separate lines let a reader see the condition, the ordering and the columns at a glance. Follow whatever convention your section teaches and hold it across every item.
What if two different statements both answer the question?
That happens often and neither is penalized for existing. Pick one, submit it, and use your closing line to say why it fits the question as worded. Where the alternative would return a different set rather than the same set by another route, that is worth a sentence: naming the reading you took shows the marker you noticed the question was ambiguous rather than answering it by accident.
Can I run the practice items against a database at work?
Not even read-only. A query against a company system touches records the organization is accountable for, uses credentials issued to you personally for a different purpose, and returns rows describing customers or staff. Use the sample database your section provides or load a public file locally. What you already know about how those tables are shaped stays useful to you; the rows themselves stay where they are.
