description	Use this skill when you need to execute SQL against the MoviePilot database. This skill guides you through connecting to the database and executing SQL statements. The database type (SQLite or PostgreSQL) and connection details are provided in the system prompt <system_info>. Applicable scenarios include: 1) The user asks about data statistics, counts, or aggregations that existing tools don't cover; 2) The user wants to inspect, modify, or fix raw database records; 3) The user asks to clean up data, update records, or perform database maintenance; 4) The user asks questions like "how many downloads", "show me site stats", "delete old records", etc.

Database Query (数据库查询)

This skill guides you through executing SQL against the MoviePilot database. Both read and write operations are supported.

Prerequisites

You need the following tools:

• execute_command - Execute shell commands to run database queries

Getting Database Connection Info

The system prompt <system_info> section already contains all the database connection details you need:

• 数据库类型 — sqlite or postgresql
• 数据库 — Full connection info:
  • For SQLite: the database file path, e.g. SQLite (/config/db/moviepilot.db)
  • For PostgreSQL: the connection string, e.g. PostgreSQL (user:password@host:port/database)

Do NOT run any detection commands. Extract the database type and connection details directly from <system_info>.

Executing Queries

SQLite Mode

Extract the database file path from <system_info> (the path inside the parentheses after SQLite).

Use execute_command to run queries:

sqlite3 -header -column <DB_PATH> "YOUR SQL QUERY HERE;"

For JSON-formatted output (easier to parse):

sqlite3 -json <DB_PATH> "YOUR SQL QUERY HERE;"

List all tables:

sqlite3 -header -column <DB_PATH> "SELECT name FROM sqlite_master WHERE type='table' ORDER BY name;"

View table schema:

sqlite3 <DB_PATH> ".schema tablename"

PostgreSQL Mode

Extract the connection parameters from <system_info> (parse user:password@host:port/database from the parentheses after PostgreSQL).

Use execute_command to run queries via psql:

PGPASSWORD=<password> psql -h <host> -p <port> -U <user> -d <database> -c "YOUR SQL QUERY HERE;"

List all tables:

PGPASSWORD=<password> psql -h <host> -p <port> -U <user> -d <database> -c "SELECT tablename FROM pg_tables WHERE schemaname='public' ORDER BY tablename;"

View table schema:

PGPASSWORD=<password> psql -h <host> -p <port> -U <user> -d <database> -c "\d tablename"

Interpret Results

After executing the query, analyze the results and present them in a clear, user-friendly format. Use aggregation, sorting, and filtering as needed.

Database Schema Reference

siteicon (站点图标)

Key columns: id, name, domain, url, base64

Common Query Examples

Count total downloads

SELECT COUNT(*) AS total FROM downloadhistory;

Recent download history

SELECT title, year, type, torrent_site, date FROM downloadhistory ORDER BY id DESC LIMIT 10;

Failed transfers

SELECT id, title, src, errmsg, date FROM transferhistory WHERE status = 0 ORDER BY id DESC LIMIT 10;

Active subscriptions

SELECT name, year, type, season, state, lack_episode FROM subscribe WHERE state = 'R';

Site upload/download statistics

SELECT name, domain, upload, download, ratio, bonus, seeding, user_level FROM siteuserdata ORDER BY upload DESC;

Media library statistics

SELECT server, library, COUNT(*) AS count FROM mediaserveritem GROUP BY server, library;

Site access success rate

SELECT domain, success, fail, ROUND(success * 100.0 / (success + fail), 1) AS success_rate FROM sitestatistic WHERE success + fail > 0 ORDER BY success_rate DESC;

Plugin data inspection

SELECT plugin_id, key FROM plugindata ORDER BY plugin_id, key;

Delete old download history (write operation)

DELETE FROM downloadhistory WHERE date < '2024-01-01';

Update subscription state (write operation)

UPDATE subscribe SET state = 'S' WHERE id = 123;

Clean up failed transfer records (write operation)

DELETE FROM transferhistory WHERE status = 0 AND date < '2024-06-01';

Safety Rules

1. Confirm before writing — For any INSERT, UPDATE, DELETE, DROP, ALTER, or TRUNCATE operation, always describe what the statement will do and ask the user to confirm before executing. For SELECT queries, execute directly without confirmation
2. Back up before destructive operations — Before executing DELETE, DROP, or TRUNCATE on important tables, suggest the user back up the data first (e.g., export with .dump for SQLite or pg_dump for PostgreSQL)
3. Use WHERE clauses — Never run UPDATE or DELETE without a WHERE clause unless the user explicitly intends to affect all rows
4. Use LIMIT for queries — When querying large tables with SELECT, add LIMIT to prevent excessive output
5. Sensitive data — The site table contains cookie, apikey, and token fields. NEVER display these values to the user. Exclude them from SELECT or replace with '***'
6. Password data — The user table contains hashed_password and otp_secret fields. NEVER display these values
7. Output limits — If the query results are very long, summarize or truncate them

SQL Dialect Differences

When writing queries, be aware of differences between SQLite and PostgreSQL:

Feature	SQLite	PostgreSQL
Boolean values	0 / 1	false / true
String concat	||	|| or CONCAT()
Current time	datetime('now')	NOW()
LIMIT syntax	LIMIT n	LIMIT n
JSON access	json_extract(col, '$.key')	col->>'key'
Case sensitivity	Case-insensitive by default	Case-sensitive
LIKE	Case-insensitive	Use ILIKE for case-insensitive

Troubleshooting

• sqlite3 not found: The sqlite3 CLI should be pre-installed in the MoviePilot Docker container. If missing, you can try using Python: python3 -c "import sqlite3; ..."
• psql not found: For PostgreSQL, if psql is not available, use Python: python3 -c "import psycopg2; ..."
• Permission denied: Database queries require admin privileges
• Table not found: Use the "list all tables" query first to verify table names
