Adding a Row Number in Query

Add a row number to result set of a SQL query

The typical pattern would be as follows, but you need to actually define how the ordering should be applied (since a table is, by definition, an unordered bag of rows). One way to do that if you don't care about a specific order otherwise is to use the leading key(s) of a covering index, the leading key(s) of the clustered index, or the columns in any group by / order by clauses. In this case I'll assume A is the single-column clustering key for t:

SELECT t.A, t.B, t.C, number = ROW_NUMBER() OVER (ORDER BY t.A)
  FROM dbo.tableZ AS t
  ORDER BY t.A;

If you truly don't care about order, you can generate arbitrary/nondeterministic row numbering using:

ROW_NUMBER() OVER (ORDER BY @@SPID)

-- or for serial plans

ROW_NUMBER() OVER (ORDER BY @@TRANCOUNT)

Little tricks I picked up from Paul White in this article (see "Paul's Solution").

Not sure what the variables in your question are supposed to represent (they don't match).

Adding Row Number on SQL SELECT

If you are using a programming language, you can keep your SQL simple:

"SELECT username, id, Days FROM Users ORDER BY Days DESC";

Then process the row number using the programming language:

if ($result->num_rows > 0) {
$rowNumber=0;
echo "<table><tr><th>ID</th><th>Name</th><th>Days</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
    $rowNumber++;
    echo "<tr><td>" . $rowNumber "</td><td>" . $row["username"]. "</td><td>" . $row["Days"]. "</td></tr>";
}
echo "</table>";
} else {
echo "0 results";
}

How to add row number to an MySQL display using ROW_NUMBER()

Window functions evaluate after GROUP BY aggregation has happened, so it doesn't make much sense to use a partition on the name, since each record at that point would be guaranteed to have a distinct name. Most likely, you want something like this:

SELECT
    name, 
    ROW_NUMBER() OVER (ORDER BY AVG(work_days), COUNT(*) DESC) AS row_num,
    AVG(work_days) AS workday_average, 
    COUNT(*) AS count
FROM work
GROUP BY
    name
HAVING
   workday_average > 2
ORDER BY
    workday_average,
    count DESC;

But this of course assumes that you are using MySQL 8+. If not, then ROW_NUMBER won't be available.

Add a row number to a microsoft access query

One way to do it is with a correlated subquery:

SELECT s.pluquo,
              (SELECT COUNT(*) 
               FROM (SELECT DISTINCT pluquo FROM SYNC002_ACCESS) AS t
               WHERE t.pluquo <= s.pluquo
              ) AS row_number
FROM (
  SELECT DISTINCT pluquo
  FROM SYNC002_ACCESS
) AS s

Or with a self join:

SELECT s1.pluquo, COUNT(*) AS row_number
FROM (SELECT DISTINCT pluquo  FROM SYNC002_ACCESS) AS s1
INNER JOIN (SELECT DISTINCT pluquo  FROM SYNC002_ACCESS) AS s2
ON s2.pluquo  <= s1.pluquo 
GROUP BY s1.pluquo

Add row number to this T-SQL query

Add: ROW_NUMBER() OVER (ORDER BY NumCars)

EDIT:

WITH    t1 AS 
( SELECT DISTINCT
            VehicleSpecs.SubmittedById ,
            COUNT(VehicleSpecs.SubmittedById) AS NumCars ,
            aspnet_Users.UserName
   FROM     VehicleSpecs
            INNER JOIN aspnet_Users ON VehicleSpecs.SubmittedById = aspnet_Users.UserId
   WHERE    ( LEN(VehicleSpecs.SubmittedById) > 0 )
   GROUP BY VehicleSpecs.SubmittedById ,
            aspnet_Users.UserName
)
SELECT  ROW_NUMBER() OVER ( ORDER BY NumCars ), *
FROM    t1
ORDER BY NumCars
