name: sql description: Run SQL queries against the WordPress development database. Use when querying database tables, inspecting Simple History events, checking WordPress data, or debugging database issues.
Run SQL Queries
You are tasked with running SQL queries against the WordPress development database.
Prerequisites
- Database credentials are stored in
CLAUDE.local.mdunder "Database Access" - Docker compose services must be running
- Commands must be run from the docker-compose project directory
Command Pattern
docker compose exec mariadb mysql -u<USER> -p<PASSWORD> <DATABASE> -e "YOUR_SQL_HERE"
Refer to CLAUDE.local.md for the actual credentials and connection details.
Examples
Show all tables
docker compose exec mariadb mysql -u<USER> -p<PASSWORD> <DATABASE> -e "SHOW TABLES;"
Query Simple History events
docker compose exec mariadb mysql -u<USER> -p<PASSWORD> <DATABASE> -e "SELECT * FROM wp_simple_history ORDER BY id DESC LIMIT 10;"
Describe a table structure
docker compose exec mariadb mysql -u<USER> -p<PASSWORD> <DATABASE> -e "DESCRIBE wp_simple_history;"
Count records
docker compose exec mariadb mysql -u<USER> -p<PASSWORD> <DATABASE> -e "SELECT COUNT(*) FROM wp_posts;"
Table Prefixes
The database contains multiple WordPress installations with different prefixes:
| Prefix | Installation |
|--------|--------------|
| wp_ | Main install (wordpress_mariadb) |
| wp_nightly_ | Nightly build |
| wp_6_0_ to wp_6_6_ | Version-specific installs |
| wp_multisite_ | Multisite install |
| wp_php74_ | PHP 7.4 install |
| wp_subfolder_ | Subfolder install |
Simple History Tables
The main Simple History tables (using wp_ prefix):
wp_simple_history- Main events tablewp_simple_history_contexts- Event context/metadata
Instructions
- Read credentials from
CLAUDE.local.md - Ask the user what SQL query they want to run (if not specified)
- Run the query using the command pattern above
- Display the results
- Offer to run follow-up queries if needed
Notes
- For complex queries, consider using
\Gat the end for vertical output - Be careful with UPDATE/DELETE queries - always confirm with user first
