Power BI for Data Analytics

Today, let's understand the next important Power BI topic:
*📊 Power BI: Native Query Explained*
🔍 *What is a Native Query?*
A native query is a manually written SQL statement used to pull data directly from the data source.
It gives *full control* over what data gets imported.
🧠 *Why Use Native Queries?*
✔️ Optimized performance
✔️ Complex SQL logic
✔️ Filter large data at source
✔️ Transformations happen in the DB, not Power BI
⚙️ *How to Use It in Power BI:*
1️⃣ Home > *Get Data* > Choose your source
2️⃣ Click *Advanced Options*
3️⃣ Paste your SQL query in the *SQL Statement* box
4️⃣ Click OK
🛑 *Things to Remember:*
⚠️ May *break query folding*
⚠️ No filter preview or incremental refresh
⚠️ Avoid hardcoding values
📌 *Example:*
```sql
SELECT customer_id, name, total_orders
FROM customers
WHERE total_orders > 10
```
✅ Only customers with more than 10 orders will be loaded – efficient & fast.
✅ *Pros:*
+ Full control
+ Supports joins & subqueries
+ Boosts performance on large datasets
❌ *Cons:*
– May block optimizations
– Harder to maintain
– Less flexible than GUI
