How to Transpose Columns in Each Group to a Single Row
Tags: sql, development, spl
Published: 2024-07-02 06:40:27

We have a database table STAKEHOLDER as follows:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/f6gk1xq1bx8j14gg7p7u.png)
We are trying to group the table by CLASS and convert all columns to a same row. Below is the desired result set:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/p5cklvnltp1xo5dl4zoj.png)
SQL code written in Oracle:

```
WITH CTE AS(
SELECT
            UP.CLASS,
            UP.NS || UP.RN AS NSR,
            UP.VAL
FROM
            (
            SELECT
                        ROW_NUMBER ()
         OVER (
           PARTITION BY S.CLASS
            ORDER BY
                        S.CLASS) RN,
                        S.*
            FROM
                        STAKEHOLDER S
            ORDER BY
                        CLASS,
                        SID) SS
UNPIVOT (VAL FOR NS IN (NAME, SID)) UP
)
SELECT
            *
FROM
            CTE
PIVOT(MAX(VAL) FOR NSR IN ('NAME1' AS NAME1,
            'SID1' AS SID1,
            'NAME2' AS NAME2,
            'SID2' AS SID2,
            'NAME3' AS NAME3,
            'SID3' AS SID3))
```
This is not difficult if we handle it with our natural way of thinking. After grouping the table by CLASS, we convert NAME and SID columns into rows and create names commanding values to be converted to columns. Format of names is the original column name + number of subgroups, like NAME1, SID1, NAME2, SID2，… for group 1 and NAME1, SID1, … for group2. Then we concatenate groups and transpose row to columns. The problem is SQL does not support dynamic row-to-column/column-to-row transposition. When the number of columns is small and columns are fixed, the language can mange to do the transpositions. As the number of columns increases, the scenario becomes more and more awkward. Enumerating all columns to be converted is complicated and SQL code becomes bloated. If columns are dynamic, SQL needs to turn to complex and roundabout ways to handle them.

Yet, it is really easy to code the transposition task with the open-source esProc SPL:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4d7w44c28snzcd2nbplk.png)
SPL is the specialized data computing engine that is based on ordered-sets. It offers the all-round abilities for performing set-oriented operations, supports stepwise coding, and provides intuitive solutions. Instead of enumerating columns, SPL can automatically scale up, making it convenient to deal with various transposition tasks.

Платформа .NET (произносится как «dot net») — это бесплатная управляемая компьютерная программная платформа с открытым исходным кодом для операционных систем Windows, Linux и macOS. Проект в основном разрабатывается сотрудниками Microsoft посредством .NET Foundation и распространяется под лицензией MIT.

В конце 1990-х годов Microsoft начала разработку среды выполнения управляемого кода и языка программирования C# как часть платформы .NET, которая включает в себя .NET Framework. В 2014 году был представлен .NET Core - кроссплатформенная версия .NET Framework с открытым исходным кодом. Последующие версии включают .NET Core 1.0, 2.0, 3.0, и выпуски .NET 5.0, 6.0, 7.0 и 8.0 в последующие годы.

Alpine Linux , который в первую очередь поддерживает и использует musl libc, поддерживается начиная с .NET Core 2.1.

Windows Arm64 изначально поддерживается, начиная с .NET 5. Ранее .NET на ARM означал приложения, скомпилированные для архитектуры x86 и работающие через уровень эмуляции ARM.

Leetcode Day 1: Two Sum Explained
Tags: leetcode, python, coding, codenewbie
Published: 2024-07-02 05:34:12

The problem is as follow:

Given an array of integers `nums` and an integer `target`, _return indices of the two numbers such that they add up to `target`_.

You may assume that each input would have **_exactly_ one solution**, and you may not use the _same_ element twice.

You can return the answer in any order.


Example 1:

```
Input: nums = [2,7,11,15], target = 9
Output: [0,1]
```
Explanation: Because nums[0] + nums[1] == 9, we return [0, 1].

Example 2:

```
Input: nums = [3,2,4], target = 6
Output: [1,2]
```
Example 3:

```
Input: nums = [3,3], target = 6
Output: [0,1]
```



Here is how I solved it:

- We want to create a dictionary named `index_map` to store the integers in `nums` and their corresponding indices.

```
index_map = {}
```

- Then, we will use enumerate to get both index `i` and value `num` of each element in `nums`.
For each integer, let's calculate the complement, which is the difference between the `target` and the current element `num`.
```
for i, num in enumerate(nums):
    n = target - num
```
- Now check the dictionary: if n is in the dictionary, it means we have found the two integers that add up to the `target` Return the `n` index and the current index as a list.
```
if n in index_map: 
    return [index_map[n], i]
```
- Else, if `n` is not in the dictionary, add the current element `num` and index to the dictionary.
```
index_map[num] = i
```

Here is the completed solution:

```
class Solution:
    def twoSum(self, nums: List[int], target: int) -> List[int]:
        index_map = {}
        for i, num in enumerate(nums):
            n = target - num
            if n in index_map: 
                return [index_map[n], i]
            index_map[num] = i
```
🚀 Mastering Loop Control in C Programming: Leveraging break and continue 🌟
Published: 2024-07-02 05:34:02

Hey Dev Community! Are you ready to enhance your C programming skills and optimize your code? Today, let's delve into the powerful world of loop control with break and continue statements.

**Understanding break and continue**
In C programming, break and continue are essential tools for managing loops effectively:

- 
**break:** This statement allows you to exit a loop prematurely based on a specified condition. It's perfect for terminating loops early when certain criteria are met, ensuring efficient program execution.

- 
**continue:** Unlike break, continue skips the current iteration of the loop and proceeds directly to the next iteration. This helps in bypassing specific iterations without exiting the loop entirely, enabling selective processing of loop iterations.

**Practical Applications**
Here’s how you can apply a break and continue in your code:

- 
**Input Validation:** Use a break to stop processing input when an invalid value is encountered, preventing further unnecessary iterations.

- 
**Error Handling:** Employ continue to skip over error-prone iterations while continuing to process valid data within the loop, enhancing program robustness and stability.

**Benefits of Using Break and Continue**
Mastering these loop control statements offers several advantages:

- 
**Enhanced Code Efficiency:**
 Exit loops early or skip unnecessary iterations to optimize program performance.

- 
**Improved Code Readability:** Clearly define loop termination conditions and iteration skips, making code logic more transparent and maintainable.

**Conclusion**
Incorporating break and continue statements into your C programming toolkit empowers you to write cleaner, more efficient code. Whether you’re validating input, implementing search algorithms, or handling error conditions, these tools enhance your ability to control loop behavior effectively.

Ready to elevate your programming skills? Dive into my detailed blog post on mastering loop control with break and continue: https://mokshelearning.blogspot.com/2024/07/programn%20to%20show%20the%20usage%20of%20break%20and%20continue.html

**Air Canada Name Change Policy**
You can correct or change your name with Air Canada up to 12 hours before departure. However, the sooner you request, the better your chances of securing the best result. To make changes, you must share your booking credentials and a supportive document depicting the correct characters of your name. The airline charges a fee if you are requesting a name change outside of the risk-free period.

**Hawaiian Airlines Name Change Policy**
Hawaiian Airlines is known for offering one of the safest flight journeys to its passengers. It also provides one of the most flexible policies for making name changes in your scheduled itinerary.  According to the **[Hawaiian Airlines Name Change Policy](https://www.flightyo.com/blog/hawaiian-airlines-name-change-policy/)**, you are allowed to change your full name with legal documents or any government-approved documents.
