I am creating a comment with reply box. With this table 'comments', how do I write a query to have it list the parent comment first(id), follow by the replies(replyTo) if any below its parent comment.
In this example, I want to list the rows in this order.
87 - comment
86 - comment
88 - reply to 86
I tried using this query, but it is listing the reply first than its parent comment.
88
86
87
$q_comments = mysql_query("SELECT * FROM ".$database['prefix']."comments
WHERE postid = '$b_post'
ORDER BY COALESCE (replyTo,id) DESC
") or die(mysql_error());
id postid reply name email
86 67 0 don xxx
87 67 0 larry xxx
88 67 86 duc xxx
Ok. I figure it out why it wasn't working. When using 'COALESCE', the column(replyTo) needed to be set to NULL and not '0'.

I'm trying to query my customlogs table (Eg: CustomData_CL) by giving the time range. The result of this query will be the filtered time ranged data. I want to find out the data size of the resulted output.
Query which I have used to fetch the time ranged o/p:
CustomData_CL
| where TimeGenerated between (datetime(2022ā09ā14 04:00:00) .. datetime(2020ā09ā14 05:00:00))
But it is giving the following error:
Can anyone please suggest on the same ?

Update, per OP request:
Please note that in addition to the use of a wrong character that caused the syntax error, your 2nd datetime year was wrong.
// Generation of mock table. Not part of the solution
let CustomData_CL = datatable(TimeGenerated:datetime)[datetime(2022-09-14 04:30:00)];
// Solution starts here
CustomData_CL

I'm preparing the material for a KQL course, and I thought about creating a challenge, based on your question.
Check out what happened when I posted your code into Kusto Web Explorer... š
How cool is that?!
I am working on a shell script that will execute mongoexport and upload it to a S3 bucket.
The goal is to extract date as a readable JSON format on data that is 45 days old.The script will run everyday as a crontab.
So basically the purpose is to archive data older than 45 days
Normal queries work intended but when I try to use variables it results an error.
The code regular format is as the following:
firstdate="$(date -v-46d +%Y-%m-%d)"
afterdate="$(date -v-45d +%Y-%m-%d)"
backup_name=gamebook
colname=test1
mongoexport --uri mongodb+srv://<user>:<pass>#gamebookserver.tvdmx.mongodb.net/$dbname
--collection $colname --query '{"gameDate": {"$gte": {"$date": "2020-09-04T00:00:00:000Z"}, "$lte": {"$date": "2020-09-05T00:00:00.000Z"}}}' --out $backup_name;
The previous code works but I want to make it more dynamic in the dates so I tried the code as shown below:
firstdate="$(date -v-46d +%Y-%m-%d)"
afterdate="$(date -v-45d +%Y-%m-%d)"
backup_name=gamebook
colname=test1
mongoexport --uri mongodb+srv://<user>:<pass>#gamebookserver.tvdmx.mongodb.net/$dbname
--collection $colname --query '{"gameDate": {"$gte": {"$date": "$firstdateT00:00:00:000Z"}, "$lte": {"$date": "$afterdateT00:00:00.000Z"}}}' --out $backup_name;
This results in the error:
2020-10-20T15:36:13.881+0700 query '[123 34 103 97 109 101 68 97 116 101 34 58 32 123 34 36 103 116 101 34 58 32 123 34 36 100 97 116 101 34 58 32 36 102 105 114 115 116 100 97 116 101 84 48 48 58 48 48 58 48 48 58 48 48 48 90 125 44 32 34 36 108 116 101 34 58 32 123 34 36 100 97 116 101 34 58 32 34 36 97 102 116 101 114 100 97 116 101 84 48 48 58 48 48 58 48 48 46 48 48 48 90 34 125 125 125]' is not valid JSON: invalid character '$' looking for beginning of value

I've read in the documentation and it says:
You must enclose the query document in single quotes ('{ ... }') to ensure that it does not interact with your shell environment.
So my overall question is that is there a way to use values in the shell environment and parse them into the query section?
Or is there a better way that might get me the same result?
I'm still new to mongodb in general so any advise would be great.
You can always put together a string by combining interpolating and non-interpolating parts:
For instance,
--query '{"gameDate": {"$gte": {"'"$date"'": "'"$firstdate"'T00:00:00:000Z"}, "$lte": {"$date": "$afterdateT00:00:00.000Z"}}}'
would interpolate the first occurance of date and the shell variable firstdate, but would passs the rest literally to mongoexport (I've picked two variables for demonstration, because I don't understand from your question, which ones you want to expand and which one you don't want to). Basically, a
'$AAAA'"$BBBB"'$CCCCC'
is in effect a single string, but the $BBBB part would undergo parameter expansion. Hence, if
BBBB=foo
you would get the literal string $AAAAfoo$CCCCC out of this.
Since this become tedious to work, an alternative approach is to enclose everything into double-quotes, which means all parameters are expanded, and manually escape those parts which you don't want to expand. You could write the last example also as
"\$AAAA$BBBB\$CCCCC"
I have a DAX formula for my Powerpivot I cannot get to solve and was hoping for help.
I have two pivot tables connected already
Showing a cohort of actions taken within Month 1,ā¦.X on the sign up month
Total Sign Ups on monthly basis
I have tried to attached the sheet here but somehow I cant so I have add a screenshot of the sheet.1
What I have so far is:
=DIVIDE(
SUM(Range[conversion to KYC completed]),
SUM('Range 1'[Sum of signups]))
But this does not give me what I want as I think Iām missing the monthly grouping somehow.
Question 1:
What I want is to get the share of actions completed within 1,...,X months out of the total sign up that given month (e.g. Jan) (so the data from Table 2)
Question 2:
In best case I would also like to show total sign ups in the beginning of the cohort to make the cohort easier to understand, so having the monthly total sign up (which the cohort is calculated based on). But now I cannot get just the totals month by month. Is there anyways just to add in a monthly total column in the pivot without applying these number as a value across all columns?
Something like this is the ultimate outcome for me 2

Thanks for the sample data Franzi. Still not too clear what you're asking for, but perhaps this will help a little.
Signed Up to Signed In Ratio =
VAR SignUpMonth = SELECTEDVALUE(Table1[Signup month], BLANK())
RETURN
DIVIDE(CALCULATE(SUM([conversion to KYC completed])),
CALCULATE(SUM(Table1[ signups]),
FILTER(ALL(Table1), Table1[Signup month] = SignUpMonth)))
So. Let's break it down.
If I understand correct, you want to see the cross section of number of signins for a given month ( x axis ) signup combo ( y axis ) and divide that number by the total signups ( y axis ) per signup month.
number of signins for a given month ( x axis ) signup combo ( y axis ):
CALCULATE(SUM([conversion to KYC completed]))
TOTAL signups ( y axis ) per signup month
CALCULATE(SUM(Table1[ signups]),
FILTER(ALL(Table1), Table1[Signup month] = SignUpMonth))
So I have a .txt file that looks like this:

I have created a grades.awk script that contains the following code:
{
FS=" "
names=$1
vi1=$2
vi2=$3
vi3=$4
rv=$5
#printf("%s ",names);
split(names,nameArray," ");
printf("%s\t",nameArray[1]); //prints the whole array of names for some reason, instead of just the name at position 1 in array ("john")
}
So my question is, how do I split this correctly? Am I doing something wrong?
How do you read line by line, word by word correctly. I need to add each column into its own array. I've been searching for the answer for quite some time now and can't fix my problem.
here is a template to calculate average grades per student
$ awk '{sum=0; for(i=2;i<=NF;i++) sum+=$i;
printf "%s\t%5.2f\n", $1, sum/(NF-1)}' file
mona 77.25
john 83.75
andreja 89.50
jasper 73.75
george 71.50
ellis 90.00
printf("%s\t",nameArray[1])
is doing exactly what you want it to do but you aren't printing any newline between invocations so it's getting called once per input line and outputting one word at a time but since you aren't outputting any newlines between words you just get 1 line of output. Change it to:
printf("%s\n",nameArray[1])
There are a few other issues with your code of course (e.g. you're setting FS in the wrong place and unnecessarily, names only every contains 1 word so splitting it into an array doesn't make sense, etc.) but I think that's what you were asking about specifically.
If that's not all you want then edit your question to clarify what you're trying to do and add concise, testable sample input and expected output.

Against each week,
I have number of orders requested in the first table
I have number of orders delivered in the second table.
I want a pivot chart which shows the same
If you are using Excel 2010 or newer you could use PowerQuery, a free add-in provided by Microsoft, to unpivot and combine your two datasets. I believe in Excel 2016 PowerQuery is already included as Get & Transform.
Create a new query with PowerQuery and open the Advanced Editor. Remove any text already appearing in the editor and use the below code to get an unpivoted and combined table.
let
Requested = Table.AddColumn(Table.UnpivotOtherColumns(Excel.CurrentWorkbook(){[Name="Requested"]}[Content], {"Week"}, "Country", "Value"), "Type", each "Requested"),
Delivered = Table.AddColumn(Table.UnpivotOtherColumns(Excel.CurrentWorkbook(){[Name="Delivered"]}[Content], {"Week"}, "Country", "Value"), "Type", each "Delivered"),
Combined = Table.Combine({Requested, Delivered})
in
Combined
The first two lines after let are getting the data from your tables (assuming your two datasets are in tables named Requested and Delivered), using Table.UnpivotOtherColumns to unpivot them and then adding a column Type to indicate if the line is for a request or a delivery.
Table.Combine simply appends one table to the other (putting all the lines from the deliveries below the requests).
Close the Advanced Editor and click Close & Load in the query editor to add the query results to an Excel sheet. Using the resulting table you can easily create a pivot table that shows the combined data.
Since the query is still connected to the source tables, anytime your data changes / gets updated you can refresh the query (similar to a pivot table) to get the new data.
