in postgresql database, have multiple reference data tables. example: - gender(id:serial, name:varchar) - sexuality(id:serial, name:varchar) - location(id:serial,name:varchar) to retrieve of information in of tables doing 3 separate select statements. example: - "select name gender; - "select name sexuality; - "select name location; how can make 1 call returns 1 row this: referencedata(allgenders:varchar[], allsexualities:varchar[], alllocations:varchar[]) i able able client side --> var genders = results.row[0].allgenders; gender in genders { print(gender); } you can use array_agg aggragate function combine values multiple rows single array, e.g. select array_agg(name) gender will return genders single array. if want information 3 tables @ once, can that: select (select array_agg(name) gender), (select array_agg(name) sexuality), (select array_agg(name) location);

i have following code append incremental number beggining of each filename. how can make start 01 instead of 1. $files = get-childitem "c:\test" $i = 1 foreach ($file in $files) { $newname = "$i" + $file rename-item $($file.fullname) $newname $i++ } several ways this, use -f (format) operator. here's how i'd write in pipeline: get-childitem "c:\test" | foreach-object -begin { $i=1 } { rename-item $_ -newname ("{0:d2}{1}" -f ($i++, $_.name)) } p.s. forget it's possible eliminate foreach-object using delay-bind scriptblock. comes in particularly handy rename-item: $i = 1 get-childitem "c:\test" | rename-item -newname {"{0:d2}{1}" -f ($i++, $_.name)}

i'm trying code input, moved center top when user start typing text. how can change justifycontent: 'center' justifycontent: 'flex-start' animation? or maybe there way? my code: <view style={styles.container}> <searchinput onchangetext={this.handleinputchange} /> </view> and styles: const styles = { container: { flex: 1, alignitems: 'stretch', justifycontent: 'center', flexdirection: 'column' } }; you should able achieve free using layoutanimation . this do, things left out: handlefocus = () => { layoutanimation.easeineaseout(); this.setstate({ issearching: true, }); }; render() { const style = { justifycontent: this.state.issearching ? 'flex-start' : 'center', }; return ( <textinput onfocus={this.handlefocus} style={style} /> ); } if doesn't work, doubt, have use animated .

i working on existing implementation of dijkstra , 1 of deliverable test whether implementation efficient solution issue @ hand or recommend alternate algorithm. question is... how should baseline existing dijkstra algorithm compare alternate? narrow scope, client using dijkstra dynamically chose best tariffs plan b2b consumers. make sense? dijkstra algorithm find shortest path in graph. test , see how effective that, need compare other algorithms. bellman–ford algorithm, a* search algorithm , etc. important notes other performance, there other important issues dijkstra doesn't work negative values. why bellman-ford has been used instead in many problems. also, dijkstra has different implementations. dijkstra's algorithm list o(v 2) while dijkstra's algorithm modified binary heap o((e + v) log v) , dijkstra's algorithm fibonacci heap o(e + v log v). bellman–ford algorithm o(ve). conclusion if need see 1 better work, first see parameters matte...

i trying assign address of 1 of structure, named node, 1 named tmp, has same type--node. however, address of tmp less 8 address of node. why that? thanks! #include <stdio.h> #include <stdlib.h> typedef struct _node { int data; struct _node *next; }node; int main() { node *node = (node*)malloc(sizeof(node)); node *tmp; tmp = node; printf("%d\n",&node); printf("%d\n",&tmp); } i guessing expected output same both lines. for happen, have print values of pointers, not addresses of pointers. after tmp = node; the value of tmp same value of node addresses of 2 variables going different. i suspect meant use: printf("%p\n", node); // use %p pointers, not %d printf("%p\n", tmp);

this question has answer here: simulating group_concat mysql function in microsoft sql server 2005? 9 answers for example, if have data-set below id item 1 2 b 3 c 1 b 1 c 2 then need sql query gives output below: id item 1 a, b, c 2 b, 3 c that how group based on id , display values pertaining column attributes in sql. replace table names table name , use below query: select src.id, src.items [items] ( select distinct t2.id, ( stuff((select t1.item + ',' [text()] [yourtable-name] t1 t1.id = t2.id order t1.id xml path ('')),1,1,'') ) [items] [yourtablename] t2 ) [src]

suppose, want seperate logic code ui code myapp.qml , myappform.ui.qml. ui.qml not support javascript logic, example,mouse events. suppose, following problem. //myappform.ui.qml import qtquick 2.4 item { rectangle { id: rectangle1 color: "#a0ebfb" anchors.fill: parent mousearea { id: mouse1 anchors.fill: parent } } } the above ui code. need separate logic code as, //myapp.qml import qtquick 2.4 myappform { mouse1{ onclicked: { rectangle1.color = 'red' } } } obviously, above not work. asking how similar. thanks. you can extend mouse area using alias property. here modified code. //myappform.ui.qml item { property alias rectmousearea: mouse1 rectangle { id: rectangle1 color: "#a0ebfb" anchors.fill: parent mousearea { id: mouse1 anchors.fill: parent } } } //myapp.qml import qtqu...

i have standart record deduplication task: have alot records text ( or other ) fields , of them corresponding same entity. merging of such records goal of task. there used , simple statistical approachs kind of tasks " probabilistic record linkage ". of them more precise , more complicated exploit same ideas https://github.com/datamade/dedupe : try weight somehow each field measure of similarity , linear composition of weighted differences measure of whole record similarity. but tasks have alot of unknown fields, amount of similar fields rather large : record1 : propa = ; propb = unknown ; propc = unknown ; .... record2 : propa = ; propb = b ; propc = unknown ; .... record3 : propa = unkown ; propb = b ; propc = d ; .... record4 : propa = a2 ; propb = unknown ; propc = unknown ; .... record5 : propa = a2 ; propb = b2 ; propc = unknown ; .... record6 : propa = x2 ; propb = b2 ; propc = d2 ; .... in case record1 can linked record3 via record2 more record4 record...
