📦 Installation

Global Installation (Recommended)

npm install -g mysql_nlp

Local Installation

npm install mysql_nlp
npx mysql_nlp --help

🛠️ Configuration

Initialize Configuration

mysql_er configure

Follow prompts to create your .env file:

DB_HOST=localhost
DB_USER=root
DB_PASSWORD=secret
DB_NAME=mydb

Initialize Connection

mysql_nlp init

🚀 Basic Usage

Simple Query

mysql_nlp query "Show all users"

/* Generated SQL */
SELECT * FROM users

Conditional Query

mysql_nlp query "Find emails from users where age > 25"

/* Generated SQL */
SELECT email FROM users WHERE age > 25

🔥 Advanced Usage

Transactions

mysql_nlp query "Start transaction: Update balance for user 5 by +100, then log transaction"

Complex Joins

mysql_nlp query "Show users with their orders from last week"

Time-Based Queries

mysql_nlp query "Count logins created in last 3 hours"

🛡️ Security Features

Input Sanitization

// Rejects queries containing:
; DROP TABLE -- DELETE FROM

Prepared Statements
```
SELECT * FROM users WHERE id = ?
```

Schema Validation

mysql_nlp query "Add new employee with salary 50000"

/* Validates against schemas.ts before executing */
INSERT INTO employees (salary) VALUES (50000)

📚 Supported Query Patterns

Pattern Type	Example Query	Generated SQL
Basic SELECT	"Show all products"	`SELECT * FROM products`
Conditional WHERE	"Find active users"	`SELECT * FROM users WHERE active=1`
JOIN Operations	"Get orders with customer details"	`SELECT * FROM orders JOIN customers...`
Aggregation	"Calculate average sales"	`SELECT AVG(sales) FROM transactions`
Time Filtering	"Recent signups last 24 hours"	`SELECT * FROM users WHERE created_at >=...`
Pagination	"Show page 3 of results (10 per page)"	`SELECT ... LIMIT 20, 10`

🧩 Extending Patterns

Add custom patterns in patterns.ts:

{
  regex: /^archive (old|inactive) (?<table>\w+)$/i,
  sqlTemplate: `UPDATE ${table} SET status = 'archived' 
               WHERE last_activity < DATE_SUB(NOW(), INTERVAL 1 YEAR)`,
  priority: 7,
  validation: async (sql) => { /* custom logic */ }
}
