How to sort the row of record and update dynamically in SQL?

seems to work fine Clarification on SQL query syntax : we have an Employee table which has two columns Emp Id and EmpName and its values looks like this:
WITH cteRowNums AS (
    SELECT EmpId,
           EmpName,
           ROW_NUMBER() OVER(ORDER BY EmpId) AS RowNum
        FROM Employee
)
UPDATE cteRowNums
    SET EmpName = CASE WHEN RowNum % 3 = 1 THEN 'Joe'
                       WHEN RowNum % 3 = 2 THEN 'John'
                       WHEN RowNum % 3 = 0 THEN 'Sam'
                  END;

How to dynamically Update/Edit/Delete existing record within a list


Tag : ruby-on-rails , By : lifchicker

will help you I would suggest using a gem like Best in Place to allow for in-place editing on certain fields in the list.
If you don't want in-place editing then utilize a modal view that contains the edit form.

Need T-SQL update statement to dynamically assign a record number


Tag : sql-server , By : General Mills

I hope this helps you . First, you want to assign a value for RecNum for all PK using ROW_NUMBER. After that, you want to update the remaining rows with the appropriate RecNum
SQL Fiddle
WITH CtePKs AS(
    SELECT *,
        RN = ROW_NUMBER() OVER(ORDER BY ID)
    FROM z2
    WHERE RIGHT(Name, 3) = '_pk'
)
UPDATE CtePKs SET RecNum = RN 

UPDATE z
    SET RecNum = x.RecNum
FROM z2 z
OUTER APPLY(
    SELECT TOP 1 Id, RecNum
    FROM z2
    WHERE
        ID < z.ID 
        AND RecNum IS NOT NULL
    ORDER BY ID DESC
)x
WHERE z.RecNum IS NULL
| ID |      Name |           Value | RecNum |
|----|-----------|-----------------|--------|
|  1 |    ad1_pk |               1 |      1 |
|  2 | ad1_addr1 | 123 Easy Street |      1 |
|  3 |    ad1_pk |               2 |      2 |
|  4 | ad1_addr1 |         99 US31 |      2 |
|  5 |  ad1_atfk |               6 |      2 |
|  6 |    ad1_pk |               3 |      3 |

I hope this helps . I want to update a profile and when I update the record, the old data that I didnot change is also updated. , You can try the following
$name = $request->input('name', $user->name);
<?php
namespace App\Http\Middleware;
class ConvertEmptyStringsToNull extends TransformsRequest
{
    /**
     * Transform the given value.
     *
     * @param  string  $key
     * @param  mixed  $value
     * @return mixed
     */
    protected function transform($key, $value)
    {
        return is_string($value) && $value === '' ? null : $value;
    }
}
protected $middleware = [
\Illuminate\Foundation\Http\Middlewar\CheckForMaintenanceMode::class,
\App\Http\Middleware\TransformsRequest::class,
\App\Http\Middleware\TrimStrings::class,
\App\Http\Middleware\ConvertEmptyStringsToNull::class,
];

Tag : haskell , By : Steve

To fix the issue you can do Solution was created in this way:
List of fields has a function which updates corresponding field in record :
fields =
  [ ("NAME", (\d x -> d{name=x}))
  , ("ADDRESS", (\d x -> d{addr=x}))
  , ... and for other fields
  ]
 initByStrings strs = foldl (\ d (x, y) -> y d(findIn x strs)}) emptyMyData fields
