dt1 transaction_1 dt2 transaction_2 dt3 transaction_3....dt80 tra_80
may01 22 jun01 56 Aug09 73
sep02 49 feb12 53 dec23 80
Now the Should be like below
dt transaction type
may01 22 transaction_1
sep02 49 transaction_1
jun01 56 transaction_2
feb12 53 transaction_2
Aug09 73 transaction_3
dec23 80 transaction_3
.... .. ......
.... .. ......
.... .. transaction_80
Plz anyone provide Query in MYSQL.
thanks,
Use this function CONCAT(string1, string2)
example:
SELECT CONCAT(dt, transaction) FROM table_name

I am trying to create a program that reads in a table of temperatures from a csv file and would like to access a a collection of temperatures based on the year and day.
the first column stands for the year the tempratures have been recorded.
the second column stands for a specific day during each month .
the rest of the column represent the temperatures each month.
For example, 2021 - 23 - 119 = 23rd June 2021 has a temperature of 119
Year Day Months from January to December
2018 18 | 45 54 -11 170 99 166 173 177 175 93 74 69
2021 23 | 13 87 75 85 85 119 190 172 156 104 39 53
2020 23 | 63 86 62 128 131 187 163 162 138 104 60 70
So far I have managed to load the data from a CSV File with clojure.data.csv. this returns a sequence of vectors into the program
(defn Load_csv_file [filepath]
(try
(with-open [reader (io/reader filepath)]
(.skip reader 1)
( let [data (csv/read-csv reader)]
(println data) )
)
(catch Exception ex (println (str "LOL Exception: " (.toString ex))))
))
I am currently trying to figure out how to implement this but my reasoning was to create three keys in a map which will take in the year, day and vector of temperatures, to then filter for a specific value.
Any advice on how i can implement this functionality.
Thanks!
i would go with something like this:
(require '[clojure.java.io :refer [reader]]
'[clojure.string :refer [split blank?]]
'[clojure.edn :as edn])
(with-open [r (reader "data.txt")]
(doall (for [ln (rest (line-seq r))
:when (not (blank? ln))
:let [[y d & ms] (mapv edn/read-string (split ln #"\s+\|?\s+"))]]
{:year y :day d :months (vec ms)})))
;;({:year 2018,
;; :day 18,
;; :months [45 54 -11 170 99 166 173 177 175 93 74 69]}
;; {:year 2021,
;; :day 23,
;; :months [13 87 75 85 85 119 190 172 156 104 39 53]}
;; {:year 2020,
;; :day 23,
;; :months [63 86 62 128 131 187 163 162 138 104 60 70]})
by the way, i'm not sure csv format allows different separators (as you have in your example.. anyway this one would work for that)
I would create a map of data that looked something like this
{2020 {23 {:months [63 86 62 128 131 187 163 162 138 104 60 70]}}}
This way you can get the data out in a fairly easy way
(get-in data [2020 23 :months]
So something like this
(->> (Load_csv_file "file.csv")
(reduce (fn [acc [year day & months]] (assoc-in acc [year day] months)) {}))
This will result in the data structure I mentioned now you just need to figure out the location of the data you want
So I have the following code:
let sql = `INSERT INTO users(email, name, surname, stellarAccount, stellarSeed) VALUES(?, ?, ?, ?, ?)`;
let new_user = [
mysql.escape(args.email),
mysql.escape(args.name),
mysql.escape(args.surname),
mysql.escape(keypair.publicKey()),
mysql.escape(utils.encrypt(Buffer.from(keypair.secret(), "utf-8"))),
];
console.log(await utils.encrypt(Buffer.from(keypair.secret(), "utf-8")));
con.query(sql, new_user, (err, results, fields) => {
if (err) {
return console.error(err.message);
}
console.log(results);
});
The problem is that instead of the encrypted value in mysql I have only blank space. I tried to console log the following:
utils.encrypt(Buffer.from(keypair.secret(), "utf-8"))
and it looked something like this:
<Buffer 01 02 02 00 78 45 8c 88 86 55 00 4f 23 8e 1f 80 a8 1d 3d c4 b0 6a 4c de 3e 60 db 43 51 8d 12 26 56 f3 70 1a 7b 01 89 65 c5 ea 7b 91 ff 71 f6 46 a6 e7 ... 162 more bytes>
In mysql the table charset is utf8mb4 and utf8mb4_0900_ai and the column that is blank is BLOB, also I wanted to set Not Null the column at it's giving me an error, I can't set BLOB to be not null ?
How can I insert the encrypted value in mysql db correcly ?
It is not for a password, I need this value afterwards, but I was thinking that encrypting it in the db would be much better than inserting it there as a plain text.
You can convert your buffer to utf-8 string and then you can save it.
buf1.toString('utf8');

i'm trying to import a txt-File to octave which contains a matrix of data.
The matrix looks like this:
49 ..1. ...1.......... ..... 49
47 ..12 ...1...... ... ..... 47
45 ..12....1...... 2....1... 45
43 ....2....1...... 2...1.... 43
41 .1..2.. .........2. .1..... 41

This is actually map/coordinate system (y-axis=azimuth, x-axis=latitude), which i have to plot. (blank=no data, .=no effects, 1=weak effects, 2=strong eff.)
The result should look like this
Because i failed to import this txt-File, i changed it into this.
49;1;1;1;1;1;1;1;2;2;3;2;1;2;2;2;3;2;2;2;2;2;2;2;2;2;2;1;2;2;2;2;2;1;1;1;1;1;1;1;49
47;1;1;1;1;1;1;1;2;2;3;4;1;2;2;2;3;2;2;2;2;2;2;1;2;2;2;1;2;2;2;2;2;1;1;1;1;1;1;1;47
45;1;1;1;1;1;1;1;2;2;3;4;2;2;2;2;3;2;2;2;2;2;2;1;4;2;2;2;2;3;2;2;2;1;1;1;1;1;1;1;45
43;1;1;1;1;1;1;2;2;2;2;4;2;2;2;2;3;2;2;2;2;2;2;1;4;2;2;2;3;2;2;2;2;1;1;1;1;1;1;1;43
39;1;1;1;1;1;1;2;3;2;3;4;2;4;2;2;2;2;3;2;2;2;2;2;4;2;1;2;3;2;2;2;2;2;1;1;1;1;1;1;39
37;1;1;1;1;1;1;2;3;2;2;4;2;4;4;2;2;2;3;2;2;2;2;2;4;2;1;2;3;2;2;2;2;2;1;1;1;1;1;1;37
and so on.
This is working with my code.
RawMap = dlmread('C:\Desktop\2576.map', ';', 0:80, 0:24)
Map = flipud(RawMap)
pcolor(Map(:,2:end-1))
To this automatically i don't want to the change the code. So i need to get the original file imported.
Any suggestions?
Thanks
Here is one approach to parse the file meaningfully:
S = fileread('testo.txt');
S = strsplit (S, "\n");
S = strvcat( S );
S = double(S);
S = S(:, 4:end-4);
S( S == double(" ") ) = 0;
S( S == double(".") ) = 1;
S( S == double("1") ) = 2;
S( S == double("2") ) = 3;
pcolor(S); axis ij;
In Om Next, when having data such as:
{:table {:name "Disk Performance Table"
:data [:statistics :performance]}
:chart {:name "Combined Graph"
:data [:statistics :performance]}
:statistics {:performance {:cpu-usage [45 15 32 11 66 44]
:disk-activity [11 34 66 12 99 100]
:network-activity [55 87 20 1 22 82]}}}
you can query it with:
[{:chart [{:data [:cpu-usage]}]}]
to get the chart, join the data and dig down cpu-usage from the performance record:
{:chart {:data {:cpu-usage [45 15 32 11 66 44]}}}
How do I get the whole performance record instead?
Another potential query is this:
[{:chart [:data]}]
but it doesn't resolve the join:
{:chart {:data [:statistics :performance]}}
There are no components as this is only about the data and the query. This is from the exercise number 2 and queries here: https://awkay.github.io/om-tutorial/#!/om_tutorial.D_Queries which uses om/db->tree to run the queries.
This is how you do it:
[{:chart [{:data [*]}]}]
which gives you:
{:chart {:data {:cpu-usage [45 15 32 11 66 44]
:disk-activity [11 34 66 12 99 100]
:network-activity [55 87 20 1 22 82]}}}
Without seeing the actual components with queries and idents, I can't be sure.
However, you should be able to query for [{:chart [:data]}]. See om/db->tree. Assuming that you have structured your components with the right queries and idents, om/db->tree converts your flat app state into a tree so that your read functions see the following data when called:
{:table {:name "Disk Performance Table"
:data {:cpu-usage [45 15 32 11 66 44]
:disk-activity [11 34 66 12 99 100]
:network-activity [55 87 20 1 22 82]}}
:chart {:name "Combined Graph"
:data {:cpu-usage [45 15 32 11 66 44]
:disk-activity [11 34 66 12 99 100]
:network-activity [55 87 20 1 22 82]}}}
If that query doesn't work, [{:chart [{:data [:cpu-usage :disk-activity :network-activity]}]}] should certainly do the trick.
I'm trying to wrap my head around the Go language and I've hit my first stumbling block with this simple example:
package main
import (
"encoding/json"
"fmt"
)
type MyStructure struct {
Integer int `json:"integer"`
Label string `json:"label"`
}
func main() {
ms := &MyStructure{9001, "over9000"}
msjson, _ := json.Marshal(ms)
fmt.Println(msjson) // expect: {"integer": 9001, "label": "over9000"}
}
My output is as follows: [123 34 105 110 116 101 103 101 114 34 58 57 48 48 49 44 34 108 97 98 101 108 34 58 34 111 118 101 114 57 48 48 48 34 125]
I'm clearly missing something obvious; could someone please point me in the right direction?
It produces a byte slice (ref : http://golang.org/pkg/encoding/json/#Marshal), use string(msjson) to get the string.
Also never ignore errors, it bites you back whenever you least expect it.
fmt.Println(string(msjson))
// or
fmt.Printf("%s\n", msjson) //shamelessly taken from #dustin's comment
