```

**Important:** the files in `posts/` and `pages/` contain HTML. Always paste them in Blogger's **HTML view**, never in the normal (compose) view.

---

## 2. Preview the site on your computer

Open `preview/index.html` in any browser (double-click it). Every page, link, filter, copy button and download button works. The yellow bar at the top reminds you it is a preview: search and Blogger features only work after publishing.

The preview is **not** the Blogger theme — Blogger only uses `theme/gtu-rdbms-hub-theme.xml`. Both use the same CSS, JavaScript and markup, so they look the same.

---

## 3. Publish on Blogger — step by step

You need a Google account and about 45–60 minutes. Do the steps in this order.

### Step 1 — Create the blog
1. Go to **blogger.com** and sign in.
2. Click **New blog** (or **Create your blog**).
3. Title: `GTU MCA RDBMS Hub`.
4. Address: choose something like `gtu-mca-rdbms-hub.blogspot.com` (pick any free name).
5. Display name: your name or "GTU MCA RDBMS Hub". Click **Finish**.

### Step 2 — Basic settings (left menu → **Settings**)
| Setting | Value |
|---|---|
| Basic → Description | `GTU MCA Semester 1 RDBMS (MC01094031) practical solutions in Oracle SQL and PL/SQL, notes and viva questions.` |
| Basic → Favicon | upload `theme/favicon-64.png` |
| HTTPS → HTTPS redirect | **On** |
| Comments → Comment location | **Hide** (this theme does not show comments; see §8) |
| Site feed → Allow blog feed | **Full** or **Until Jump Break** (needed so the practical links can find each post — do **not** choose *None*) |
| Crawlers and indexing → Enable search description | **On**, then write the same description as above |
| Formatting → Time zone | (GMT+05:30) India Standard Time |

### Step 3 — Install the theme
1. Left menu → **Theme**.
2. Click the small **▼ arrow** next to **Customize** → **Backup** → **Download** (keeps a copy of the old theme, just in case).
3. Click the **▼ arrow** again → **Restore** → **Upload** → choose `theme/gtu-rdbms-hub-theme.xml`.
4. If Blogger asks to remove widgets that are not in the new theme, click **Remove widgets**.
5. Click the **▼ arrow** → **Mobile settings** → choose **Desktop** → **Save**. (The theme is fully responsive; this makes phones get it too.)

### Step 4 — Create the 10 pages
For **each** row of the table, do:
1. Left menu → **Pages** → **+ New page**.
2. Type the **title exactly as shown** (it decides the page URL).
3. Click the toolbar's first drop-down (**Compose view**) and switch to **HTML view**.
4. Open the file from `pages/` in Notepad (or any text editor), **Select all → Copy**, then paste into Blogger.
5. Click **Publish** → **Confirm**.

| Title to type (first publish) | File | URL Blogger creates |
|---|---|---|
| Practicals | `pages/practicals.html` | `/p/practicals.html` |
| SQL Commands | `pages/sql-commands.html` | `/p/sql-commands.html` |
| PLSQL Programs | `pages/plsql-programs.html` | `/p/plsql-programs.html` |
| RDBMS Notes | `pages/rdbms-notes.html` | `/p/rdbms-notes.html` |
| Viva Questions | `pages/viva-questions.html` | `/p/viva-questions.html` |
| Downloads | `pages/downloads.html` | `/p/downloads.html` |
| About | `pages/about.html` | `/p/about.html` |
| Disclaimer | `pages/disclaimer.html` | `/p/disclaimer.html` |
| Privacy Policy | `pages/privacy-policy.html` | `/p/privacy-policy.html` |
| Contact | `pages/contact.html` | `/p/contact.html` |

- After publishing **PLSQL Programs** you can edit it and change the title to **PL/SQL Programs** — the URL does not change.
- **Contact page:** before publishing, replace `[your-email-address-here]` with your real address (or delete that line and add Blogger's Contact Form gadget, §6).
- After each page is live, open it (Pages → *View*) and check that the address bar matches the third column. If Blogger created a different URL, see §7.

### Step 5 — Create the 10 practical posts
Open `docs/blogger-setup-sheet.md` — it lists the exact title, labels, permalink and search description for each post. For **Set 1, then Set 2, … up to Set 10**:
1. Left menu → **Posts** → **+ New post**.
2. Paste the **Post title** from the setup sheet.
3. Switch to **HTML view** and paste the whole content of `posts/set-0N.html`.
4. In the right-hand **Post settings** panel:
   - **Labels:** type the labels exactly, separated by commas, e.g. `Set-01, Practicals, Basic SQL`. The `Set-01` … `Set-10` labels are essential — all practical links, the sidebar and previous/next navigation use them.
   - **Permalink → Custom permalink:** e.g. `gtu-mca-rdbms-set-1-solution`.
   - **Search description:** paste from the sheet.
5. Click **Publish**.

Publishing Set 1 first and Set 10 last makes the homepage *Latest tutorials* list show the newest sets first.

### Step 6 — Check the live site
Open your blog address and check:
- [ ] The homepage shows the hero, the six quick cards, the 10 set cards and *Latest tutorials*.
- [ ] Every top-menu item opens the right page.
- [ ] Clicking a set card opens that practical (the link is upgraded automatically to the post's real address; before that it shows the post through its label).
- [ ] On a practical: **Copy** buttons copy only their own block; **Download .sql** saves a file; *Previous/Next practical* work.
- [ ] On the Practicals page the topic filters and the search box narrow the cards.
- [ ] On a phone: the ☰ menu opens and closes, code scrolls sideways, nothing is cut off.

### Step 7 — Search engines (optional but recommended)
1. Blogger already creates `https://YOUR-BLOG.blogspot.com/sitemap.xml` and a correct `robots.txt` automatically. Leave **Custom robots.txt** and **Custom robots header tags** **off** unless you know you need them.
2. Go to **search.google.com/search-console**, add your blog address as a property (Blogger blogs verify automatically when you use the same Google account), then **Sitemaps → Add** `sitemap.xml`.
3. The theme already outputs canonical URLs and Open Graph tags (through Blogger's `all-head-content`), a meta description from each post's *Search description*, and `noindex` for search-result pages.

---

## 4. How labels are used

| Label | Purpose |
|---|---|
| `Set-01` … `Set-10` | Identifies each practical. Links use `/search/label/Set-0N`, and the theme's script replaces that with the post's real URL by reading the blog feed. Use **exactly one** post per Set label. |
| `Practicals` | Shows the *Home › Practicals › post* breadcrumb and highlights PRACTICALS in the menu. |
| `Basic SQL`, `Constraints`, `Joins`, `Subqueries`, `Aggregate Functions`, `Views and Sequences`, `PLSQL`, `Procedures`, `Functions`, `Cursors`, `Triggers` | Topic labels. Clicking one on a post shows every post on that topic. |

---

## 5. Updating navigation links

The top menu, footer, sidebar and homepage cards are part of the theme. To change a link:
1. **Theme → ▼ → Edit HTML**.
2. Press **Ctrl+F** (inside the code editor) and search for the old URL, e.g. `/p/practicals.html`.
3. Change it (there may be several occurrences — header, footer, homepage, sidebar) and click **Save** (💾 icon).

Links **inside** posts and pages are in those posts/pages; edit them in HTML view.

---

## 6. Adding gadgets (optional)

**Layout** shows a *Sidebar gadgets* area under the built-in sidebar. Click **Add a Gadget** there to add, for example, **Contact Form**, **Popular Posts** or **Labels**. Blogger renders them with its default markup.

---

## 7. If Blogger created a different page URL

Blogger makes the page URL from the title used the first time you publish. If, for example, *PLSQL Programs* became `/p/plsql-programs_10.html` (this happens when a page with that URL existed before and was deleted):
- Easiest: delete the page, **empty it from the trash too**, and create it again with the exact title; or
- Replace the URL in the theme (§5) and in any post/page that links to it.

---

## 8. Comments

The theme deliberately shows no comment section, which keeps the pages fast and avoids spam moderation. If you want comments, keep Settings → Comments → *Comment location: Embedded* and add Blogger's default comment includable to the Blog widget (Theme → Edit HTML). This is optional and not needed for the site to work.

---

## 9. Adding a future practical (e.g. Set 11) or changing content

**Without the generator (simple):**
1. Copy any `posts/set-XX.html`, edit the text and code in a text editor, and publish it as a new post with labels `Set-11, Practicals, …`.
2. Add a card for it: Theme → Edit HTML → search for `Set-10` → duplicate the `<article class="set-card">…</article>` block of Set 10 in the homepage section and change `Set-10`/`10` to `Set-11`/`11`. Do the same for the sidebar `<li>` and in `pages/practicals.html`.

**With the generator (recommended for bigger changes):** everything is produced from `tools/content/*.py`.
```bash
pip install sqlglot duckdb          # needed to compute expected outputs
python3 tools/build.py              # rebuilds posts/, pages/, downloads/, theme/, preview/, docs/
```
- Edit a practical in `tools/content/setNN.py` (each question is a `Q(...)` with text, code, explanation).
- Change theme layout in `tools/theme.py`, styles in `tools/assets/site.css`, behaviour in `tools/assets/site.js`.
- A new set: create `tools/content/set11.py` following the same structure and change `range(1, 11)` in `tools/build.py` to `range(1, 12)`.
- Re-publish only what changed: re-upload the theme and re-paste the edited posts/pages.

Expected outputs of SELECT statements are **computed** by running the Oracle SQL (translated with `sqlglot`) on DuckDB against the same sample data, so they always match the data shown in the article.

## 10. Fixing common Blogger XML errors

| Error message when uploading/saving the theme | Cause and fix |
|---|---|
| *The entity name must immediately follow the '&' in the entity reference* | A raw `&` in the HTML part of the theme. Write `&amp;` (or put scripts inside `//<![CDATA[ … //]]>`). |
| *The element type "br" must be terminated by the matching end-tag* | XML needs self-closed tags: `<br/>`, `<img …/>`, `<input …/>`, `<meta …/>`. |
| *Open quote is expected for attribute* | Every attribute value needs quotes: `class='x'`. |
| *The content of elements must consist of well-formed character data or markup* | A `<` inside text or a script outside CDATA. Use `&lt;` or wrap the script in CDATA. |
| *More than one widget was found with id: …* | Two widgets share an id. Give each a unique id (`HTML1`, `HTML2`, …). |
| *Invalid variable declaration in page skin* | A `$` or `<Variable>` inside `<b:skin>`. Keep plain CSS only. |
| *We were unable to save your template … widget … not found* | You removed a widget that Layout still lists. Re-upload the full theme file. |
| Theme uploads but the page is blank | Check Settings → *Mobile settings → Desktop*, then clear the browser cache. |

The theme file was validated with an XML parser before delivery. If you edit it, keep a backup first (Theme → Backup).

## 11. Troubleshooting

- **A set card opens a "Posts labelled Set-0N" list instead of the article** — either the post is not published yet, its label is misspelt (`Set-1` instead of `Set-01`), or the blog feed is set to *None*. The list still shows the article, so nothing is broken.
- **Download button missing** — the browser has JavaScript disabled, or the post was pasted in compose view (re-paste in HTML view).
- **Copy button says "Press Ctrl+C"** — the browser blocked the clipboard; the code is selected for you.
- **Code shows as one long line** — the content was pasted in compose view. Delete it and paste again in HTML view.

## 12. About the content

- All question wording and numbering is copied from the official GTU syllabus PDF (MC01094031, w.e.f. 2024-25), including its spelling. Where the PDF splits one instruction across two numbers (Set 2 items 2–3 and 4–5, Set 5 items 12–13) or repeats a question (Set 5 items 2 and 10), the numbering is kept and the article explains it.
- Set 1 uses the PDF's own department records. The other sets' rows are sample data built around the PDF's examples (Surat, Sejal, Chirag, Piyush, Ajaykumar, ORACLE FUNDAMENTALS, …), because the PDF gives no data for them.
- All solutions target **Oracle 10g or above** and avoid newer-only features (no `FETCH FIRST`, identity columns or `LISTAGG`); places where newer versions differ are noted in the articles.
- Code has been syntax-reviewed and the SQL statements were parse-checked; it has **not** been executed on an Oracle server by the author. Expected outputs are computed from the sample data — please run the scripts in your lab.
