# Troubleshooting Guide

## Error: "Unknown column 't.amount' in 'SELECT'"

### Kemungkinan Penyebab:
1. **OPcache belum di-clear** - PHP masih menggunakan file lama
2. **Struktur database berbeda** - Kolom `amount` mungkin tidak ada atau nama berbeda
3. **File belum ter-update** - Meskipun sudah `git pull`, file mungkin belum benar-benar ter-update

---

## Solusi di Production

### Step 1: Clear OPcache
```bash
# Di production server
cd /www/wwwroot/api.btekno.cloud/api

# Clear OPcache via PHP CLI
php -r "opcache_reset();"

# Atau restart PHP-FPM
systemctl restart php-fpm
# atau
/www/server/php/83/bin/php-fpm restart
```

### Step 2: Verify File Sudah Ter-update
```bash
# Cek apakah file sudah benar-benar ter-update
grep -n "COALESCE(t.amount, 0)" src/Modules/Retribusi/Summary/DailySummaryService.php

# Harus muncul di line 46 dan 61
# Line 46: COALESCE(t.amount, 0) as tariff_amount
# Line 61: COALESCE(t.amount, 0)
```

### Step 3: Verify Struktur Database
```bash
# Login ke MySQL
mysql -u sql_retribusi -p sql_retribusi

# Cek struktur tabel tariffs
DESCRIBE tariffs;

# Harus ada kolom:
# - location_code
# - gate_code  
# - category
# - amount  <-- INI HARUS ADA!
```

### Step 4: Test Query Manual
```bash
# Di MySQL client
mysql -u sql_retribusi -p sql_retribusi < bin/verify_query.sql

# Atau jalankan query ini manual:
```

```sql
SELECT 
    DATE(e.event_time) as summary_date,
    e.location_code,
    e.gate_code,
    e.category,
    COUNT(*) as total_count,
    COALESCE(t.amount, 0) as tariff_amount
FROM entry_events e
INNER JOIN locations l ON e.location_code = l.code AND l.is_active = 1
INNER JOIN gates g ON e.location_code = g.location_code 
    AND e.gate_code = g.gate_code 
    AND g.is_active = 1
LEFT JOIN tariffs t ON e.location_code = t.location_code
    AND e.gate_code = t.gate_code
    AND e.category = t.category
WHERE DATE(e.event_time) = CURDATE()
GROUP BY 
    DATE(e.event_time),
    e.location_code,
    e.gate_code,
    e.category,
    COALESCE(t.amount, 0)
LIMIT 5;
```

### Step 5: Test Script Lagi
```bash
cd /www/wwwroot/api.btekno.cloud/api
php bin/daily_summary.php 2025-12-16
```

## Cek Database Lokal

### Step 1: Setup .env (jika belum)
```bash
# Copy .env.example ke .env
cp .env.example .env

# Edit .env, isi dengan database lokal:
DB_HOST=localhost
DB_NAME=sql_retribusi
DB_USER=sql_retribusi
DB_PASS=your_password_here
```

### Step 2: Jalankan Script Check Database
```bash
php bin/check_database.php
```

### Step 3: Verify Query di Lokal
```bash
# Via MySQL client
mysql -u sql_retribusi -p sql_retribusi < bin/verify_query.sql
```

### Step 4: Test Daily Summary di Lokal
```bash
php bin/daily_summary.php 2025-12-16
```

## Apply Migrations

### Migration yang Tersedia:
1. `001_create_audit_logs.sql` - Tabel audit_logs
2. `002_create_hourly_summary.sql` - Tabel hourly_summary
3. `003_create_realtime_events.sql` - Tabel realtime_events

### Cara Apply (Lokal):
```bash
# Via MySQL command line
mysql -u sql_retribusi -p sql_retribusi < migrations/001_create_audit_logs.sql
mysql -u sql_retribusi -p sql_retribusi < migrations/002_create_hourly_summary.sql
mysql -u sql_retribusi -p sql_retribusi < migrations/003_create_realtime_events.sql
```

### Cara Apply (Production):
```bash
# Di production server
cd /www/wwwroot/api.btekno.cloud/api

# Backup dulu!
mysqldump -u sql_retribusi -p sql_retribusi > backup_$(date +%Y%m%d_%H%M%S).sql

# Apply migration
mysql -u sql_retribusi -p sql_retribusi < migrations/001_create_audit_logs.sql
mysql -u sql_retribusi -p sql_retribusi < migrations/002_create_hourly_summary.sql
mysql -u sql_retribusi -p sql_retribusi < migrations/003_create_realtime_events.sql
```

## Jika Masih Error

### Cek Log Error Detail:
```bash
# Di production
cd /www/wwwroot/api.btekno.cloud/api
php bin/daily_summary.php 2025-12-16 2>&1 | tee error.log
```

### Cek Apakah Tabel Tariffs Ada:
```sql
-- Di MySQL
SHOW TABLES LIKE 'tariffs';
SELECT COUNT(*) FROM tariffs;
```

### Cek Apakah Ada Data di Entry Events:
```sql
-- Di MySQL
SELECT COUNT(*) FROM entry_events WHERE DATE(event_time) = CURDATE();
```

## Quick Fix (Jika OPcache Issue)

```bash
# Di production, restart PHP-FPM
systemctl restart php-fpm

# Atau via aaPanel
# PHP → PHP-FPM → Restart

# Lalu test lagi
cd /www/wwwroot/api.btekno.cloud/api
php bin/daily_summary.php 2025-12-16
```
