php - Select one value of one colum of an array obtained with pdo -

-

i have following code :

$foo = $bdd->prepare($qry); $foo->execute(); $result = $foo->fetchall();

in $qry, have select join between tables beatles b et status s (on columns status_id), such result following :

code :

b.id    b.firstname    b.lastname    b.status_id   s.status_id     s.status  0       john           lennon        0             0               mort 1       paul           mccartney     1             1               vivant 2       ringo          starr         1             1               vivant 3       george         harrison      0             0               mort

(the first line columns' names in tables, isn't inside result of query)

i want select in php s.status of ringo starr, instance. how can ?

thanks

if want retrieve value of status ringo starr, need values of other fields within page, (assuming array has come indexed id), access $result[2]['status']. otherwise, change select statement select values of id , status.

as side note, in select statement you'll need give aliases potentially b.status_id , s.status_id; when join, column names taken , table names ignored in terms of returned - b.status_id b_status_id, s.status_id s_status_id make sure got correct values both of these. may have done of course - looked though might have not, judging column names gave.

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
