Convert SQL to MediaWiki

Why Convert SQL to MediaWiki?

Converting SQL files to MediaWiki format enables you to publish database documentation directly on Wikipedia, corporate wikis, and any MediaWiki-powered knowledge base. While SQL scripts are designed for database engines, MediaWiki markup creates rich, interactive pages with sortable tables, section headings, and automatic table of contents — making complex database schemas accessible to a wider audience including project managers, analysts, and technical writers.

MediaWiki's table syntax is exceptionally well-suited for documenting database schemas. Each table definition becomes a formatted wikitable with sortable columns showing field names, data types, constraints, and descriptions. The "wikitable" CSS class provides consistent styling across all MediaWiki installations, ensuring your database documentation looks professional whether it's on an internal company wiki or a public knowledge base.

SQL queries converted to MediaWiki format are displayed using the <syntaxhighlight> tag with SQL language support, providing color-coded syntax highlighting that makes complex queries easier to understand. Comments from the SQL source are converted into wiki text that provides context and explanations for each query or schema element.

For organizations using MediaWiki as their documentation platform, SQL-to-MediaWiki conversion eliminates the tedious process of manually reformatting database schemas into wiki markup. Teams can maintain their SQL scripts as the source of truth and regenerate wiki documentation whenever the database evolves, keeping documentation accurate and up to date without manual effort.

Key Benefits of Converting SQL to MediaWiki:

• Wiki-Ready Output: Generates standard wikitable markup recognized by all MediaWiki installations
• Sortable Tables: Schema documentation tables include sortable column headers
• Syntax Highlighting: SQL queries rendered with color-coded highlighting via syntaxhighlight tags
• Automatic TOC: Section headings generate a navigable table of contents
• Collaborative Editing: Wiki format allows team members to enhance documentation
• Category Support: Output can be categorized within your wiki's taxonomy
• Template Integration: Compatible with existing MediaWiki templates and infoboxes

Practical Examples

Example 1: Schema Documentation for Wiki

Input SQL file (schema.sql):

-- Employee management tables
CREATE TABLE departments (
    dept_id INT PRIMARY KEY,
    dept_name VARCHAR(100) NOT NULL,
    manager_id INT,
    budget DECIMAL(12,2)
);

CREATE TABLE employees (
    emp_id INT PRIMARY KEY,
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    dept_id INT REFERENCES departments(dept_id),
    hire_date DATE NOT NULL
);

Output MediaWiki file (schema.wiki):

= Employee Management Database =

== Departments Table ==
{| class="wikitable sortable"
|-
! Column !! Type !! Constraints
|-
| dept_id || INT || PRIMARY KEY
|-
| dept_name || VARCHAR(100) || NOT NULL
|-
| manager_id || INT ||
|-
| budget || DECIMAL(12,2) ||
|}

== Employees Table ==
{| class="wikitable sortable"
|-
! Column !! Type !! Constraints
|-
| emp_id || INT || PRIMARY KEY
|-
| first_name || VARCHAR(50) || NOT NULL
|-
| last_name || VARCHAR(50) || NOT NULL
|-
| dept_id || INT || FK → departments(dept_id)
|-
| hire_date || DATE || NOT NULL
|}

Example 2: Query Documentation

Input SQL file (analytics.sql):

-- Top 10 departments by headcount
SELECT d.dept_name,
       COUNT(e.emp_id) AS headcount,
       AVG(e.salary) AS avg_salary
FROM departments d
JOIN employees e ON d.dept_id = e.dept_id
GROUP BY d.dept_name
ORDER BY headcount DESC
LIMIT 10;

Output MediaWiki file (analytics.wiki):

== Top 10 Departments by Headcount ==


SELECT d.dept_name,
       COUNT(e.emp_id) AS headcount,
       AVG(e.salary) AS avg_salary
FROM departments d
JOIN employees e ON d.dept_id = e.dept_id
GROUP BY d.dept_name
ORDER BY headcount DESC
LIMIT 10;


'''Tables used:''' departments, employees

'''Output columns:'''
* Department name
* Employee headcount
* Average salary

Example 3: Data Seed Reference

Input SQL file (seed.sql):

-- Default system roles
INSERT INTO roles (role_id, role_name, description) VALUES
(1, 'admin', 'Full system administrator'),
(2, 'editor', 'Content editor with publish rights'),
(3, 'viewer', 'Read-only access to content'),
(4, 'moderator', 'Community moderation privileges');

Output MediaWiki file (seed.wiki):

== Default System Roles ==

{| class="wikitable"
|-
! Role ID !! Role Name !! Description
|-
| 1 || admin || Full system administrator
|-
| 2 || editor || Content editor with publish rights
|-
| 3 || viewer || Read-only access to content
|-
| 4 || moderator || Community moderation privileges
|}

''4 records defined for the '''roles''' table.''

Frequently Asked Questions (FAQ)

Q: What is MediaWiki markup?

A: MediaWiki markup is the text formatting language used by Wikipedia, Fandom, and thousands of other wikis running MediaWiki software. It uses special syntax for headings (== Heading ==), bold ('''bold'''), tables ({| ... |}), links ([[Link]]), and templates. When you edit a Wikipedia article in source mode, you're writing MediaWiki markup. It renders as formatted HTML when the wiki page is viewed.

Q: How are SQL table schemas formatted in MediaWiki?

A: CREATE TABLE statements are converted to MediaWiki wikitable format with column headers for field name, data type, and constraints. The table uses the "wikitable sortable" class for consistent styling and interactive sorting. Each column definition becomes a row in the wiki table, with constraints like PRIMARY KEY, NOT NULL, and FOREIGN KEY references clearly documented.

Q: Can I paste the output directly into Wikipedia?

A: Yes, the generated MediaWiki markup can be pasted directly into the source editor of any MediaWiki-powered wiki, including Wikipedia. The output uses standard wikitable classes and syntax that render correctly on all MediaWiki installations. For Wikipedia specifically, ensure the content meets Wikipedia's notability and sourcing guidelines before publishing.

Q: Does the converter handle SQL syntax highlighting?

A: Yes! SQL queries are wrapped in MediaWiki's <syntaxhighlight lang="sql"> tags, which provide color-coded syntax highlighting when rendered on wikis with the SyntaxHighlight extension (standard on Wikipedia and most MediaWiki installations). This makes complex SQL queries much more readable in the wiki output.

Q: Which SQL dialects are supported?

A: The converter supports standard ANSI SQL and all major dialect extensions including MySQL/MariaDB, PostgreSQL, SQLite, Microsoft SQL Server, and Oracle. Vendor-specific features like AUTO_INCREMENT, SERIAL, IDENTITY, and custom data types are all recognized and properly documented in the MediaWiki output.

Q: How are special characters handled in the conversion?

A: MediaWiki markup uses pipe characters (|) and curly braces as special syntax. The converter properly handles these characters in SQL content, escaping or encoding them where necessary to prevent conflicts with wiki table syntax. SQL strings containing pipe characters, template-like syntax, or other special wiki characters are handled correctly.

Q: Can I convert SQL files with multiple databases?

A: Yes, SQL files containing CREATE DATABASE statements and schemas for multiple databases are organized into separate wiki sections. Each database gets its own top-level heading, with tables and queries organized underneath. The automatic table of contents generated by MediaWiki makes it easy to navigate between database sections.

Q: Is the output compatible with Fandom and other MediaWiki sites?

A: Yes! The generated markup uses standard MediaWiki syntax that works on all MediaWiki-powered platforms including Fandom (formerly Wikia), Miraheze, WikiMedia projects, and any self-hosted MediaWiki installation. The wikitable CSS class and syntax highlighting tags are universally supported across the MediaWiki ecosystem.
