##  What SQLShell Does

**SQLShell is a desktop SQL interface specifically designed for analyzing data files.** It's not a database client - instead, it lets you load CSV, Parquet, Excel, and other data files and query them with SQL using DuckDB's fast analytical engine.

### 🔥 Key Features

<table>
<tr>
<td width="33%">

**⚡ Fast File Analysis**
Load data files and search through millions of rows quickly. Built on DuckDB for analytical performance.

</td>
<td width="33%">

**🎯 Smart Execution**
`F5` runs all queries, `F9` runs current statement. Simple keyboard shortcuts for iterative analysis.

### 📁 **File-Based Data Analysis**

**Important**: SQLShell works with data files, not live databases. It's designed for:

- **📊 Data Files** - CSV, Parquet, Excel, TSV, JSON files
- **🗃️ Local Analysis** - Load files from your computer for SQL analysis  
- **⚡ Fast Queries** - DuckDB engine optimized for analytical workloads
- **🔍 Data Exploration** - Search and filter capabilities across your datasets

**Not supported**: Live database connections (MySQL, PostgreSQL, etc.). Use dedicated database clients for those.

### 💫 What Makes SQLShell Useful

- **🏎️ DuckDB Powered** - Fast analytical queries on data files
- **📊 Multiple File Formats** - CSV, Parquet, Excel, Delta, TSV, JSON support
- **🎨 Clean Interface** - Simple SQL editor with result display
- **🔍 Search Functionality** - Find data across result sets quickly
- **🚀 Zero Database Setup** - No server installation or configuration needed

## 🔍 Search and Filter Features

### ⚡ **Result Search with Ctrl+F**

Once you have query results, use `Ctrl+F` to search across all columns:

- **Cross-column search** - Finds terms across all visible columns
- **Case-insensitive** - Flexible text matching
- **Instant feedback** - Filter results as you type
- **Numeric support** - Search numbers and dates

### 💪 **Practical Use Cases**

| Use Case | Search Term | What It Finds |
|----------|-------------|---------------|
| **Error Analysis** | `"error"` | Error messages in log files |
| **Data Quality** | `"null"` | Missing data indicators |
| **ID Tracking** | `"CUST_12345"` | Specific customer records |
| **Pattern Matching** | `"*.com"` | Email domains |

**Workflow**: Load file → Query data → `Ctrl+F` → Search → `ESC` to clear

-- After encoding
SELECT 
    category_Electronics,
    category_Books,
    category_Clothing
FROM products_encoded;
```

### 📊 **Column Analysis**
Right-click columns for quick statistical analysis and correlation insights.

SELECT 
    category,
    AVG(price) as avg_price,
    COUNT(*) as count
FROM sales_data 
GROUP BY category
ORDER BY avg_price DESC;
```

### Multi-File Analysis
```sql
-- Join data from multiple loaded files
SELECT 
    c.customer_name,
    SUM(o.order_total) as total_spent
FROM customers c
JOIN orders o ON c.customer_id = o.customer_id
GROUP BY c.customer_name
ORDER BY total_spent DESC
LIMIT 10;
```
