How to extract a column from this generated table?

wish help you to fix your issue I have this generated table and I want to parse it with Mojo::DOM and extract the columns 'Username' and 'No. comments' in 2 different arrays. I can't figure out how to do that. Can you help me? Or maybe some guidance to some documentation. a lot guys! , You can do this with Mojo::DOM by iterating over the cells.
code :
use Mojo::DOM;

my (@usernames, @comment_count);
my $dom = Mojo::DOM->new->parse(do { local $/ = undef; <DATA>});
$dom->find('table.table tr')->each(sub {
    my $cells = $_->find('td');

    push @usernames, $cells->[0]->all_text; # because there's an <a> inside
    push @comment_count, $cells->[-1]->text;
});

__DATA__
...
[
    [0] "user8",
    [1] "user9",
    [2] "user11",
    [3] "user1",
    [4] "user2",
    [5] "user3",
    [6] "user4",
    [7] "user5"
]
[
    [0] 0,
    [1] 0,
    [2] 0,
    [3] 23,
    [4] 2,
    [5] 3,
    [6] 4,
    [7] 5
]

fixed the issue. Will look into that further I have the following MySQL-code: , I would write it instead as:
code :
sum(value in ('1', '2', '3', '4', '5', '6', '7', '8', '9', '10') )
sum(value > '0')

What is the T-SQL syntax to extract a specific word from a column of Table A based on the value of a column in Table B?

fixed the issue. Will look into that further If the order of these words is always the same (no DEL CPL or CPL REV DEL) this should be easy:
code :
DECLARE @Details TABLE(Detail VARCHAR(100));
INSERT INTO @Details VALUES
 ('STD RN')
,('CPL DEL REV')
,('DLX RN')
,('FAS REV')
,('CJS SUP REV')
,('COS RN');


DECLARE @Categories TABLE(Category VARCHAR(100));
INSERT INTO @Categories VALUES
 ('STD')
,('CPL DEL')
,('DLX')
,('FAS')
,('CJS SUP')
,('COS');

SELECT d.Detail
      ,c.Category
FROM @Details AS d
INNER JOIN @Categories AS c ON d.Detail LIKE c.Category + '%'
Detail  Category
STD RN  STD
CPL DEL REV CPL DEL
DLX RN  DLX
FAS REV FAS
CJS SUP REV CJS SUP
COS RN  COS

code :
ALTER TABLE `messages`
MODIFY `aggregate_version` INT UNSIGNED NOT NULL;

around this issue What would be the SQL (standard, or any major variant) to produce a table like the following? , You are looking for a cumulative sum:
code :
select rownum, sum(rownum) over (order by rownum)
from all_objects
where rownum <= 10;

I wish this helpful for you I am trying to create vba code to generate kml data from access data , got the solution... here's my final code...
code :
'define input box for target table
Dim Message, Title, Default, MyValue
Message = "Enter table/query name"  ' Set prompt.
Title = "kmlwriter"    ' Set title.
Default = "tablequeryname"    ' Set default.
MyValue = inputbox(Message, Title, Default)
'/inputbox

'define writing object for export
Dim fso As Object
Set fso = CreateObject("Scripting.FileSystemObject")

'define recordset for target table fetch and looping
Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM [" & MyValue & "]")

'define counter and output
Dim Fileout As Object
Dim i As Integer

'set output directory, replace 'peta' with something for sub directory of your currentdatabase
Set Fileout = fso.CreateTextFile(CurrentProject.Path & "\peta\" & MyValue & ".kml", True, True)

'standard header for kml
Fileout.write "<?xml version=""1.0"" encoding=""UTF-8""?><kml><Document><!-- Begin Style Definitions -->"


If Not (rs.EOF And rs.BOF) Then
    rs.MoveFirst 'Unnecessary in this case, but still a good habit

    Do Until rs.EOF = True

        'output name and coordinates, I place those 3 in order, latitude, longitude, point name
        Fileout.write vbNewLine & "<Placemark>"
        Fileout.write "<Point><altitudeMode>clampToGround</altitudeMode><extrude>0</extrude>"
        'rs(0) = latitude, rs(1) = longitude
        Fileout.write "<coordinates>" & rs(1) & "," & rs(0) & ",0" & "</coordinates></Point>"
        'rs(2) = point name
        Fileout.write vbNewLine & "<name>" & rs(2) & "</name><description><![CDATA["

        'output description for points
        For i = 3 To rs.Fields.Count - 1
             Fileout.write "<br><b>" & rs(i).Name & "</b> =" & rs(i)
        Next i
        Fileout.write "]]></description></Placemark>"

        'Move to the next record. Don't ever forget to do this.
        rs.MoveNext
    Loop
Else
    MsgBox "There are no records in the recordset."
End If

'standard kml footer
Fileout.write vbNewLine & "</Document></kml>"

Fileout.Close

'open save directory in mazimized windows
Shell "C:\WINDOWS\explorer.exe """ & CurrentProject.Path & "\peta", vbMaximizedFocus
