Six filters on one ledger-detail table, each reported with rows returned, dollars returned and what the result supports, make up this query writing problem from AC442 Unit 5. Searches like "ac 442 unit 5 assignment example", "ac442 unit 5 sample" and "ac442 unit 5 example" land here.
What a finished AC442 Unit 5 query writing problem looks like
Five pages, roughly three quarters of a page per problem. Every problem opens with the controller's question as asked, then the finished SELECT, a result line and a short interpretation. The first isolates manual entries by source code and returns 1,214 lines. The second narrows those to weekend posting dates and returns 38. The third looks for manual lines of 5,000 dollars or more that land on an exact thousand, testing the remainder after dividing by 1,000, and returns 22 lines worth 214,000. The fourth hunts blank descriptions twice: equality with an empty string finds 44, while a version adding IS NULL and trimming spaces finds 61, and the gap of 17 is explained. The fifth returns 96 lines posted more than ten days after their period ended, and the sixth tests who posted to revenue accounts.
How a AC442 Unit 5 example is structured
Problems move from broad to narrow, so each later filter reads as a refinement of an earlier one and the row counts shrink in a way a reader can follow. The question precedes the code because a grader compares the two to decide whether the filter does what was asked. Result lines always carry both a count and a dollar sum, since in accounting a hundred small lines and one large line are different findings. Interpretation is held to one or two sentences and stays disciplined about scope: a weekend posting is unusual, not improper, and the text says so. The blank-description problem sits fourth on purpose, where the difference between an empty string and a null becomes the lesson of the set, shown as two results side by side rather than argued in prose. Assumptions about the table's columns are listed once, at the top.
The controller's question first
Each problem is framed in the words a controller would use, so the grader can hold the finished filter against the request it answers.
Count and dollars on every result
Rows returned and their sum appear together, because thirty-eight lines worth a few hundred dollars and thirty-eight worth six figures are different findings.
Empty is not null
Two versions of the blank-description test return 44 and 61 lines, and the 17 nulls the first version misses are named as the difference.
Unusual, not improper
Every interpretation stops at what the rows show, describing flagged lines as worth examining and leaving any judgment to supporting documents.
Columns assumed at the top
Source code, posting date, period, account, amount, description and posting user are defined once, with the type each is assumed to carry.
Where marks go in AC442 Unit 5
Filters that return the wrong population without anyone noticing are what graders hunt for in this unit, which is why a result with no row count gets marked down even when the query happens to be right. The empty-string trap is the classic case: a description test using equality alone misses every null and understates the finding. Date filters on posting dates that ignore time stamps can drop the last day of a period. Conclusions treating a flagged line as fraud overreach, and rubrics in an accounting course deduct for claims the rows cannot carry. Queries pasted as screenshots of a tool rather than as finished text are hard to check and lose clarity marks. Missing dollar totals weaken journal entry tests in particular, since materiality is judged in currency rather than in counts.

AC442 Unit 5 questions, answered
Why pair every row count with a dollar total?
Because accounting judgments turn on amounts. Thirty-eight weekend postings could total a few hundred dollars or several hundred thousand, and the finding changes completely between the two. Reporting both lets a reader weigh the result without rerunning anything, and AC442 rubrics typically expect the count at minimum, so adding the sum costs nothing and strengthens the answer.
Does a flagged entry mean something went wrong?
No, and the sample says so after each result. A manual entry posted on a Saturday may be a controller finishing the close, and a round-thousand amount may be an accrual estimate. The query identifies lines worth examining; supporting documents decide whether any of them is a problem, which is work beyond a single-table filter.
Which SQL dialect does the sample use?
Standard SQL where possible, with any product-specific function noted. The weekend test, for instance, needs a day-of-week function whose name differs between database products, so the sample shows the version for the product your section uses and names the equivalent. Send your section's platform and the queries are written to run on it directly.
