Fabric Tenant and Workspace Management

Scenario: You have a Fabric tenant that contains a workspace.

User Capabilities: User1 can connect to DW1 via the Azure SQL Analytics endpoint.
XMLA Read-Write Access: To ensure read-write access to DS1 via the XMLA endpoint, you must first modify the C1 settings.
Fabric Admin Portal Recommendations:
- From the Tenant settings, set Allow XMLA to Enabled.
- From the Capacity settings, set XMLA to Read Write.
- From the Tenant settings, ensure the relevant feature is set

Fundamental SQL Retrieval Examples

Basic Selection and Filtering

List full details of all hotels
```
SELECT * FROM Hotel;
```

List full details of all hotels in London

SELECT * FROM Hotel WHERE city = 'London';

List names and addresses of all guests in London
Alphabetically ordered by name. Strictly speaking, using LIKE '%London%' might also find rows with an address like: ’10 London Avenue, New York’.
```
SELECT guestName, guestAddress FROM Guest 
WHERE address LIKE '%London%'
ORDER BY guestName;
```
List double or family

Four-Stroke Engine Operation

The four-stroke engine operates through four distinct stages:

Intake: Air enters the cylinder, mixing with atomized fuel.
Compression: The air and fuel mixture is compressed by the upward movement of the piston.
Power (Combustion): The burning fuel forces the piston downward with great force, producing useful work.
Exhaust: The upward movement of the piston cleans the cylinder by expelling spent gases.

Two-Stroke Engine Mechanics

Two-stroke engines are piston engines where
