-- Initial Database Setup for Quote & Invoice System
-- Run this first to create the basic tables

-- Create customers table
CREATE TABLE IF NOT EXISTS customers (
    id SERIAL PRIMARY KEY,
    name VARCHAR(255) NOT NULL,
    street VARCHAR(255) NOT NULL,
    city VARCHAR(100) NOT NULL,
    state VARCHAR(2) NOT NULL,
    zip_code VARCHAR(10) NOT NULL,
    account_number VARCHAR(50),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- Create quotes table
CREATE TABLE IF NOT EXISTS quotes (
    id SERIAL PRIMARY KEY,
    quote_number VARCHAR(50) UNIQUE NOT NULL,
    customer_id INTEGER REFERENCES customers(id),
    quote_date DATE NOT NULL,
    tax_exempt BOOLEAN DEFAULT FALSE,
    tax_rate DECIMAL(5,2) DEFAULT 8.25,
    subtotal DECIMAL(10,2) DEFAULT 0,
    tax_amount DECIMAL(10,2) DEFAULT 0,
    total DECIMAL(10,2) DEFAULT 0,
    has_tbd BOOLEAN DEFAULT FALSE,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- Create quote_items table
CREATE TABLE IF NOT EXISTS quote_items (
    id SERIAL PRIMARY KEY,
    quote_id INTEGER REFERENCES quotes(id) ON DELETE CASCADE,
    quantity VARCHAR(20) NOT NULL,
    description TEXT NOT NULL,
    rate VARCHAR(50) NOT NULL,
    amount VARCHAR(50) NOT NULL,
    item_order INTEGER NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- Create indexes for better performance
CREATE INDEX IF NOT EXISTS idx_quotes_quote_number ON quotes(quote_number);
CREATE INDEX IF NOT EXISTS idx_quotes_customer_id ON quotes(customer_id);
CREATE INDEX IF NOT EXISTS idx_quote_items_quote_id ON quote_items(quote_id);

-- Insert sample customer
INSERT INTO customers (name, street, city, state, zip_code, account_number) 
VALUES ('Braselton Development', '5337 Yorktown Blvd. Suite 10-D', 'Corpus Christi', 'TX', '78414', '3617790060')
ON CONFLICT DO NOTHING;
