How to list the products under each category in sql? side by side

I'm a bit of a beginner in sql and I need your help.
I'm sorry that I don't know if the question is correct.
now the code gives this;
+---------+----------+-------------+------------+
| id | CompanyId| DealId | price |
+---------+----------+-------------+------------+
| 1 | 1 | 1 | 100 |
| 2 | 1 | 2 | 50 |
| 3 | 1 | 3 | 25 |
| 4 | 2 | 1 | 1000 |
| 5 | 2 | 2 | 2000 |
| 6 | 2 | 3 | 2500 |
+---------+----------+-------------+------------+
but this is what i want;
+---------+----------+-------------+------------+------------+--+
| id | companyId| DealName1 | DealName2 | DealName3 | |
+---------+----------+-------------+------------+------------+--+
| 1 | 1 | 100 | 50 | 25 | |
| 2 | 2 | 1000 | 2000 | 2500 | |
| 3 | 3 | value | value | value | |
| 4 | 4 | value | value | value | |
+---------+----------+-------------+------------+------------+--+

select CompanyId
,[1] as DealName1
,[2] as DealName2
,[3] as DealName3
from (select CompanyId, DealId, price from t) t
pivot (sum(price) for DealId in([1],[2],[3])) p
CompanyId

Running Totals of Commuter in Bus per stop at specified time using TSQL

I have a problem i needed to solve using sql server 2008. Below are the tables:
CommuterTrip_Details Table:
CREATE TABLE [dbo].[CommuterTrip_Details](
[TripID] [int] NOT NULL,
[TripStartStation] [varchar](20) NULL,
[TripStartTime] [time](7) NULL,
[TripEndStation] [varchar](20) NULL,
[TripEndTime] [time](7) NULL)
BusTrip_Times Table:
CREATE TABLE [dbo].[BusTrip_Times](
[BusID] [int] NOT NULL,
[StationID] [varchar](50) NULL,
[DepartTripTime] [time](7) NULL)
Below is the content of CommuterTrip_Details Table:
+------+----------------+------------------+---------------+------------------+
|TripID|TripStartStation| TripStartTime | TripEndStation| TripEndTime |
+------+----------------+------------------+---------------+------------------+
| 1 | Station_01 | 07:00:00.0000000 | Station_03 | 07:15:00.0000000 |
| 2 | Station_01 | 07:01:00.0000000 | Station_05 | 07:17:00.0000000 |
| 4 | Station_02 | 07:12:00.0000000 | Station_08 | 07:23:00.0000000 |
| 5 | Station_02 | 07:15:00.0000000 | Station_10 | 07:30:00.0000000 |
| 7 | Station_03 | 07:20:00.0000000 | Station_10 | 07:48:00.0000000 |
| 8 | Station_04 | 07:22:00.0000000 | Station_06 | 07:51:00.0000000 |
| 9 | Station_05 | 07:31:00.0000000 | Station_09 | 07:53:00.0000000 |
| 10 | Station_06 | 07:35:00.0000000 | Station_10 | 08:02:00.0000000 |
+------+----------------+------------------+---------------+------------------+
Below is the content of BusTrip_Times Table:
+-------+------------+------------------+
| BusID | StationID | DepartTripTime |
+-------+------------+------------------+
| 1 | Station_01 | 07:00:00.0000000 |
| 2 | Station_01 | 07:05:00.0000000 |
| 3 | Station_01 | 07:10:00.0000000 |
| 8 | Station_02 | 07:15:00.0000000 |
| 14 | Station_03 | 07:25:00.0000000 |
| 17 | Station_04 | 07:25:00.0000000 |
| 18 | Station_05 | 07:30:00.0000000 |
| 19 | Station_05 | 07:35:00.0000000 |
| 21 | Station_06 | 07:40:00.0000000 |
+-------+------------+------------------+
Desired Result:
enter image description here
Explanation:
BusID = 1, boarded 1 commuter in Station_01 then commuter alighted in Station_03. Same is true with BusID = 2.
BusID = 8, boarded 2 commuters in station_02, up till station_08, where 1 commuter alighted, and 1 remained till station_10
Rest of the bus has the same concept.
To count the boarded commuters, TripStartStation = StationID and TripStartTime <= DepartTripTime.
The TripStartTime must get the closest DepartTripTime. I manage to get this using ROW_NUMBER() OVER PARTITION.

Notify in .NET application if SQL data has changed

I have got two tables. Table A contains the main data in every change state, Table B has the detail data.
Table A
| ID | Name |
| 1 | House |
| 2 | Tree |
| 3 | Car |
Table B
| ID | FK | DateTime | Color | Type |
| 1 | 1 | 2017-26-01T13:00:00 | Red | Bungalow |
| 2 | 2 | 2017-26-01T13:05:00 | Brown | Oak |
| 3 | 1 | 2017-26-01T13:10:00 | Green | Bungalow |
| 4 | 3 | 2017-26-01T13:15:00 | Yellow | Smart |
| 5 | 1 | 2017-26-01T13:20:00 | White | Bungalow |
| 6 | 3 | 2017-26-01T13:25:00 | Black | Smart |
Result to watch
| ID | Name | DateTime | Color | Type |
| 1 | House | 2017-26-01T13:20:00 | White | Bungalow |
| 2 | Tree | 2017-26-01T13:05:00 | Brown | Oak |
| 3 | Car | 2017-26-01T13:25:00 | Black | Smart |
The current state of an entity in Table A is described by the record with the youngest timestamp in Table B.
Now, I want to be nofitied, if an entity gets a new state (new record in Table B) or a new entity is created (new records in Table A and B), i.e. it could look like.
New result to watch
| ID | Name | DateTime | Color | Type |
| 1 | House | 2017-26-01T13:20:00 | White | Bungalow |
| 2 | Tree | 2017-26-01T13:05:00 | Brown | Oak |
| 3 | Car | 2017-26-01T19:25:00 | Silver | Smart |
| 4 | Dog | 2017-26-01T20:25:00 | White / Black | Poodle |
With SqlDependency it is not possible to be notified for a statement which contains GROUP BY with MAX aggregate, window functions or TOP clause. So I have no idea how I can get the last detail data for an entity.
Is there any possibility to create a statement for this requirement or are there any other ways to be notified after changes for this result?

You can create and use SQL Triggers usin CLR

MySQL Subquery Display in UPPERCASE

[DONE] for those who need this.. I will edit this and put the answer below..
How to make LName and FName all CAPS using subquery?
I already make all LName and FName CAPS but not in subquery using this code

OUTPUT:
+-----------+-----------+
| Lastname | Firstname |
+-----------+-----------+
| MONTANO | GERALD |
| ALEJANDRO | LEONARD |
| MONTEZ | GARY |
| GUILLERMO | JACKIE |
| SANCHEZ | VERNA |
| GABORNI | MICHELLE |
+-----------+-----------+
Table Trainers
+-----------+-----------+----------+-------+
| TrainerNo | LName | FName | Rate |
+-----------+-----------+----------+-------+
| 00804871 | Montano | Gerald | 200 |
| 00807461 | Alejandro | Leonard | 175 |
| 00807462 | Montez | Gary | 150 |
| 00823253 | Guillermo | Jackie | 200 |

+-----------+-----------+----------+-------+
ANSWER:
Select UPPER(Lname) AS "Lastname", UPPER(FName) AS "Firstname" from Trainers Where Rate <= (Select Max(Rate) from Trainers);

IF you want to return the first name concatenated with the second name in upper case in a sub-query. Then you can do this.
Select * from Table Name, (Select UPPER(LName) + UPPER(FName) FROM Trainers) as Name

merge single table column with different types

Table Columns
or_cv_no
here is where 'cv_no' and 'or_no' stored
type
different types are 'CV' and 'OR'
amount
here is where 'cv_amt' and 'or_amt' stored
date
data that is being fetched has same date
my query is this
SELECT IIF(type = 'CV', or_cv_no) AS cv_no, IIF(type = 'CV', amount) AS cv_amt, IIF(type = 'OR', or_cv_no) AS or_no, IIF(type = 'OR', amount) AS or_amt FROM transacAmt
and the output is
how can i output it to look like this sample:
| cv_no | cv_amt | or_no | or_amt |
|---------------------------------|
| 1234 | 1,500 | 4321 | 1,200 |
|-------+--------+-------+--------|
| 7777 | 1,700 | 2222 | 1,760 |
|-------+--------+-------+--------|
| 1111 | 1,900 | 3333 | 1,530 |
|-------+--------+-------+--------|
| | | 5355 | 1,420 |
|-------+--------+-------+--------|
| | | 1355 | 4,566 |
EDIT: The output must be like this: marked 'x' must be removed.. or be filled by data
