I have the following asc table:
+---------------------------------------------+
| Report |
+----------+----------+-------------+---------+
| Store | Total |
+----------+----------+-------------+---------+
| A | 2723 |
| B | 7277 |
+----------+----------+-------------+---------+
I need to update the total while threre are updates running on my database.
How can I do that?
I already have the method that gets updated total.
But how can I persist the total on the terminal screen?
You can achieve this using the following gems
https://github.com/ruby/curses
https://github.com/tj/terminal-table
Example :
require 'terminal-table'
require "curses"
Curses.init_screen
Curses.crmode
Curses.noecho
Curses.stdscr.keypad = true
begin
x = 0
y = 0
loop do
table = Terminal::Table.new do |t|
t << ['Random 1', Random.rand(1...10)]
t.add_row ['Random 1', Random.rand(10...100)]
end
Curses.setpos(x, y)
output = table.render.to_s
Curses.addstr(output)
Curses.refresh
sleep 1
end
ensure
close_screen
end

Is there a way to reshape the data in pig?
The data looks like this -
id | p1 | count
1 | "Accessory" | 3
1 | "clothing" | 2
2 | "Books" | 1
I want to reshape the data so that the output would look like this--
id | Accessory | clothing | Books
1 | 3 | 2 | 0
2 | 0 | 0 | 1
Can anyone please suggest some way around?
If its a fixed set of product line the below code might help, otherwise you can go for a custom UDF which helps in achieving the objective.
Input : a.csv
1|Accessory|3
1|Clothing|2
2|Books|1
Pig Snippet :
test = LOAD 'a.csv' USING PigStorage('|') AS (product_id:long,product_name:chararray,rec_cnt:long);
req_stats = FOREACH (GROUP test BY product_id) {
accessory = FILTER test BY product_name=='Accessory';
clothing = FILTER test BY product_name=='Clothing';
books = FILTER test BY product_name=='Books';
GENERATE group AS product_id, (IsEmpty(accessory) ? '0' : BagToString(accessory.rec_cnt)) AS a_cnt, (IsEmpty(clothing) ? '0' : BagToString(clothing.rec_cnt)) AS c_cnt, (IsEmpty(books) ? '0' : BagToString(books.rec_cnt)) AS b_cnt;
};
DUMP req_stats;
Output :DUMP req_stats;
(1,3,2,0)
(2,0,0,1)
I have a Table Witch look like the below table
TableVeiw<Transaction>
---------------------------------------------------------------------
| id | Transaction date | Name | type | Debit Amount | Credit Amount|
|---------------------------------------------------------------------|
| 1 | 21/02/2016 |Invoice|Credit | | 12000 |
|---------------------------------------------------------------------|
| 2 | 21/02/2016 |Payment|Debit | 20000 | |
|---------------------------------------------------------------------|
| Total Debit | Total Credit |
-----------------------------
The data in Debit amount and Credit amount come from one property of Transaction Object the code snnipet of how to populate those columns is below:
tcCreditAmmout.setCellValueFactory(cellData -> {
Transaction transaction = cellData.getValue() ;
BigDecimal value = null;
if(transaction.getKindOfTransaction() == KindOfTransaction.CREDIT){
value = transaction.getAmountOfTransaction();
}
return new ReadOnlyObjectWrapper<BigDecimal>(value);
});
tcDebitAmmout.setCellValueFactory(cellData -> {
Transaction transaction = cellData.getValue() ;
BigDecimal value = null;
if(transaction.getKindOfTransaction() == KindOfTransaction.DEBIT){
value = transaction.getAmountOfTransaction();
}
return new ReadOnlyObjectWrapper<BigDecimal>(value);
});
I need to calculate the total of :Total Debit(See the above table) and Total Credit (See the above table) every time the TableView item changes via Javafx Bindings, but i have no idea how to acheive this.
Note: Total Debit and Total Credit are Labels ,
Assuming you have
TableView<Transaction> table = ... ;
Label totalDebit = ... ;
Label totalCredit = ... ;
then you just need:
totalDebit.textProperty().bind(Bindings.createObjectBinding(() ->
table.getItems().stream()
.filter(transaction -> transaction.getKindOfTransaction() == KindOfTransaction.DEBIT)
.map(Transaction::getAmountOfTransaction)
.reduce(BigDecimal.ZERO, BigDecimal::add),
table.getItems())
.asString("%.3f"));
and of course
totalCredit.textProperty().bind(Bindings.createObjectBinding(() ->
table.getItems().stream()
.filter(transaction -> transaction.getKindOfTransaction() == KindOfTransaction.CREDIT)
.map(Transaction::getAmountOfTransaction)
.reduce(BigDecimal.ZERO, BigDecimal::add),
table.getItems())
.asString("%.3f"));
If getAmountOfTransaction might change while the transaction is part of the table, then your table's items list must be constructed with an extractor.
I have a model Counter which returns the following records:
name.....flowers.....counter
vino.....rose.........1
vino.....lily.........1
gaya.....rose.........1
rosi.....lily.........1
vino.....lily.........1
rosi.....rose.........1
rosi.....rose.........1
I want to display in the table like:
name | Rose | Lily |
---------------------
Vino | 1 | 2 |
---------------------
Gaya | 1 | 0 |
---------------------
Rosi | 2 | 1 |
I want to display the count of flowers for each distinct name. I have tried the following and wondering how can I do it elegantly?
def counter_results
#counter_results= {}
Counter.each do |name|
rose = Counter.where(flower: 'rose').count
lily= Counter.where(flower: 'lily').count
#counter_results['name'] = name
#counter_results['rose_count'] = rose
#counter_results['lily_count'] = lily
end
return #counter_results
end
which I don't get the hash values.
This will give you slightly different output, but I think it is probably closer to what you want than what you showed.
You can use the query:
Counter.group([:name, :flowers]).sum(:counter)
To get a result set that looks like:
{ ["vino", "rose"] => 1, ["vino", "lily"] => 2, ["gaya", "rose"] => 1, ["gaya", "lily"] => 0, ... }
And you can do something like this to generate your hash:
def counter_results
#counter_results = {}
Counter.group([:name, :flowers]).sum(:counter).each do |k, v|
#counter_results[k.join("_")] = v
end
#counter_results
end
The resulting hash would look like this:
{
"vino_rose" => 1,
"vino_lily" => 2,
"gaya_rose" => 1,
"gaya_lily" => 0,
...
}
Somebody else may have a better way to do it, but seems like that should get you pretty close.
I'm not sure what the appropriate title for this question so if someone could help me with that also, it would be nice.

I have a CSV file that looks something like
ID | Num
a | 1
a | 2
a | 3
b | 4
b | 5
c | 6
c | 7
I need the result to be:
ID | Num
a | 1,2,3,4
b | 4,5
c | 6,7
Currently, my solution is:
ary = CSV.open('some_file')
final = Array.new
id = ary[1][0] # ary[0] is "id"
numJoin = ary[1][1]
(1..ary.length).each do |i|
if id == ary[i+1][0]
numJoin = numJoin + "," + ary[i+1][1]
else
final << [id,numJoin]
id = ary[i+1][0]
numJoin = ary[i+1]]1]
end
end
It works, but I would like to have the opportunity to learn other ways to solve this, as I think there should be simpler ways to do this..
Thanks in advance.
You can use group_by, which groups by the return value of the block passed to it, in this case, it's the ID.
ary = ary.group_by { |v| v[0] }
P.S That file ain't looking like a CSV.
If i have a table in a WebFocus Raport design
+--------+---------+--------+---------+
| left_1 | right_1 | left_2 | right_2 |
+--------+---------+--------+---------+
| v11 | p11 | v21 | v21 |
+--------+---------+--------+---------+
| v12 | p12 | v22 | v22 |
....
How to do a such table with syllabus column titles:
+-------+-------+-------+-------+
| One | Two |
+-------+-------+-------+-------+
| left | right | left | right |
+-------+-------+-------+-------+
| v11 | p11 | v21 | v21 |
+-------+-------+-------+-------+
| v12 | p12 | v22 | v22 |
....
Thank you
Sorry for the delay of the answer :)
To rename columns, with the AS command. Example:
TABLE FILE SYSTABLE
PRINT NAME
COMPUTE LEFT1/A3 = 'v11'; AS 'left';
COMPUTE RIGHT1/A3 = 'p11'; AS 'right';
COMPUTE LEFT2/A3 = 'v21'; AS 'left';
COMPUTE RIGHT2/A3 = 'p21'; AS 'right';
IF RECORDLIMIT EQ 10
END
To put the heading columns, you can work with the ACROSS command but it will be more tricky that if u use simply SUBHEAD. With the same example:
TABLE FILE SYSTABLE
PRINT NAME NOPRINT
COMPUTE LEFT1/A3 = 'v11'; AS 'left';
COMPUTE RIGHT1/A3 = 'p11'; AS 'right';
COMPUTE LEFT2/A3 = 'v21'; AS 'left';
COMPUTE RIGHT2/A3 = 'p21'; AS 'right';
IF RECORDLIMIT EQ 10
ON TABLE SUBHEAD
"<+0>One<+0> Two"
ON TABLE PCHOLD FORMAT HTML
ON TABLE SET HTMLCSS ON
ON TABLE SET STYLE *
UNITS=IN, PAGESIZE='Letter',
LEFTMARGIN=0.500000, RIGHTMARGIN=0.500000,
TOPMARGIN=0.500000, BOTTOMMARGIN=0.500000,
SQUEEZE=ON, GRID=OFF, ORIENTATION=LANDSCAPE, $
TYPE=REPORT,FONT='ARIAL',SIZE=9,$
TYPE=TABHEADING,HEADALIGN=BODY,$
TYPE=TABHEADING, LINE=1, ITEM=1, COLSPAN=2, SQUEEZE=ON,$
TYPE=TABHEADING, LINE=1, ITEM=2, COLSPAN=2, SQUEEZE=ON,$
ENDSTYLE
END
Hope it helps!
I'm not entirely sure if you load the headers as a field or if that is the field name
But this might help you
Define fields
TITL1/A3 = 'One';
TITL2/A3 = 'Two';
BLANK/A1 = '';
Edit the Left and Right title fields to remove the _1 or _2
Print the fields BY BLANK NOPRINT
Add
ON BLANK SUBHEAD
"
You can also add more rows to the subhead if you need more titles
You can easily do it by embedding HTML/CSS scripts in report(.fex) file.
just add the HTML/css code at the end of the file.
For eg.
-HTMLFORM BEGIN // to start styling your generated report table with HTML/CSS
TABLE tr
td:first-child // applies on 1st row ONLY.It can be td or th.
{
colspan = "2"; //to merge 2 columns
}
-HTMLFORM END //end HTML.
So the first row must have two cells having title "ONE" and "TWO"(in your case), and both cells must have property of colspan = "2"
Also you can refer:
Colspan propery from here
manipulating first row of table from here
Second option is to write the whole code in a file and save it in .htm/.html format and just insert the file in to WEBFOCUS(.fex) file.For eg.
-HTMLFORM BEGIN
-INCLUDE HTML_FILE.HTML
-HTMLFORM END
Hope it helps.Thanks.
