Ghost in the SQL Data School Fire Case Solution: Step-by-Step SQL Walkthrough
Solve the Ghost in the SQL Data school fire case with this step-by-step SQL guide: find the 14-minute early caller using time filters, joins, and witness data.
The school fire case is the headline mystery in Ghost in the SQL Data, and it's the one that hooks most players: a call reported a school fire 14 minutes before the first witness saw flames. If you're stuck, this Ghost in the SQL Data school fire case solution breaks the investigation into clear, repeatable SQL steps. Finding that early caller matters because it's the moment the game teaches you that timestamps and joins — not gut instinct — crack a case. Below is a full walkthrough of the Ghost in the SQL Data school fire case solution, built around the query logic the game actually asks you to use.
How the School Fire Case Works
Ghost in the SQL Data frames every case as a data investigation. In this scenario, you're exploring a year of Paris emergency call records, and the puzzle hinges on a single anomaly: someone reported a school fire well before any witness confirmed it. That gap of roughly 14 minutes is your anchor.
Community reports and the official store description both point to the same core idea — the early call is the clue, and SQL is the tool you use to isolate it. The game doesn't hand you the answer; it hands you a database and a question.
Here's what makes this case a great teaching moment:
- Time filtering teaches you to narrow results with
WHEREclauses on timestamps. - Joins connect call records to witness statements or location data.
- Sorting (
ORDER BY) surfaces the earliest call at the scene. - Aggregation helps you compare call volume around the incident window.
One important note from player experience: the in-game SQL engine is intentionally basic. Community members have flagged that functions like DATEPART, DATEDIFF, and EXTRACT aren't available, so you'll lean on simpler string and comparison tricks instead. Keep that in mind as you build your queries.
What You're Actually Looking For
Your target is a call record that meets three conditions:
| Condition | What It Means in SQL Terms |
|---|---|
| Same location as the fire | Filter on the school's address or location ID |
| Timestamp before witnesses | WHERE timestamp < first witness time |
| Plausible reporter | Join to caller or incident tables |
Once you isolate records matching all three, the earliest one is your suspect call. That's the backbone of any Ghost in the SQL Data school fire case solution.
Building the School Fire Case Solution Query
Let's walk through the logic step by step. Exact table and column names vary by build, so treat the queries below as templates — swap in the real field names your database inspector shows you.
Step 1: Find the Fire Incident Record
Start by locating the school fire in the incident or call table. You're looking for a row that mentions a school and a fire.
SELECT *
FROM calls
WHERE description LIKE '%school%'
AND description LIKE '%fire%';
The LIKE operator with wildcards is your friend here, especially since advanced date functions may be unavailable. Community players have noted that SUBSTRING works when other string functions don't, so keep it in your toolkit.
Step 2: Pull the Witness Timeline
Next, find when the first witness actually saw the fire. That timestamp is your cutoff.
SELECT witness_time, location
FROM witnesses
WHERE location = 'School Address'
ORDER BY witness_time ASC;
Sorting ascending gives you the earliest witness observation at the top. Jot that timestamp down — it's the reference point for the whole case.
Step 3: Find Calls Before the Witness
Now the payoff. Query the call table for records at the school location that occurred before the first witness timestamp.
SELECT call_id, caller_name, call_time, description
FROM calls
WHERE location = 'School Address'
AND call_time < 'Witness Timestamp'
ORDER BY call_time ASC;
The top result is your 14-minute-early caller. This is the heart of the Ghost in the SQL Data school fire case solution — the query that turns a hunch into evidence.
Step 4: Identify the Caller
With the call ID in hand, join to the caller or person table to get a name and any linked details.
SELECT c.call_id, p.name, p.role, c.call_time
FROM calls c
JOIN people p ON c.caller_id = p.person_id
WHERE c.call_id = 'Your Call ID';
A quick tip from player experience: the game applies JOIN before WHERE implicitly, which trips up some newcomers. If your results look off, double-check how your join conditions interact with your filters.
Common Mistakes in the School Fire Case
Even a solid Ghost in the SQL Data school fire case solution can go sideways if you hit these snags. Here are the pitfalls community players run into most.
| Mistake | Why It Happens | Fix |
|---|---|---|
| Using unsupported date functions | DATEDIFF/EXTRACT unavailable | Compare timestamps directly or use SUBSTRING |
| Forgetting time zone context | Paris local time vs. stored time | Confirm how times are stored |
| Filtering only by description | Misses location-based calls | Add a location filter |
| Ignoring join order | Implicit JOIN before WHERE | Reorder logic or test incrementally |
| Assuming the first row is the answer | Unsorted results | Always ORDER BY call_time ASC |
The join-order issue is worth repeating. One reviewer specifically called out "the implicit ordering of JOIN before WHERE" as a stumbling block. If a query returns nothing when you expect rows, that's often the culprit.
A Debugging Checklist
When your query returns zero rows or too many, run through this:
- Does the location string match exactly (spelling, accents)?
- Is your timestamp comparison using the right format?
- Are you filtering on the correct table?
- Did you sort before reading the top result?
Reading the Results Like a Detective
The SQL gets you to the answer, but the case also asks you to interpret it. Once you've found the early caller, the game wants you to explain the anomaly — why did this person call before anyone else saw the fire?
This is where Ghost in the SQL Data blends data skills with light deduction. Look for supporting details in your joined results:
- Caller role — a staff member, a passerby, or someone tied to the school?
- Call timing — is it isolated or part of a cluster of calls?
- Description wording — does the report sound firsthand or secondhand?
Community discussion around other cases (like the Paris bank robbery and the hospital stalker) shows that players sometimes find the narrative logic ambiguous. If the school fire case feels unclear, focus on the data trail: the earliest matching call is the intended answer, even if the story leaves some threads loose.
Comparing Cases for Context
It helps to see how the school fire case fits alongside the game's other investigations.
| Case | Core SQL Skill | Data Focus |
|---|---|---|
| School Fire | Time filtering + joins | Call timestamps |
| Hospital Stalker | String matching (SUBSTRING) | Suspect records |
| Paris Bank Robbery | Pattern sorting | Security scores |
Noticing these patterns makes you faster at every case — and it's exactly the kind of transferable skill the game is designed to build.
Tips to Solve It Faster
If you want to move through the school fire case efficiently, these habits pay off. They're drawn from player experience and general SQL best practice.
- Inspect tables first. Before writing queries, look at column names and sample rows.
- Build queries incrementally. Add one filter at a time and check results.
- Use
LIMITorTOPto preview rows without scrolling through hundreds. - Comment your logic. Even short notes help you retrace steps.
- Re-read the case prompt. The 14-minute detail is your compass.

Why This Case Teaches Real SQL
The school fire case isn't just a puzzle — it's a compact lesson in the skills that matter most for querying real data. Filtering by time, joining related tables, and sorting results are the daily bread of data work. The game's stripped-down SQL engine, while limiting for veterans, keeps beginners focused on logic rather than syntax trivia.
Reviews reflect this split. Some experienced players found the SQL too basic and finished cases quickly, while newcomers praised the step-by-step guidance and error help. If you're new to SQL, the school fire case is one of the best places to practice because the goal is concrete: find the early caller.
Community reports also note the game is short and easy for SQL veterans — one reviewer said reaching solutions "only takes a few WHERE clauses." That's good news if you're stuck: the answer is usually simpler than you think. Trust the straightforward query.
