sql server - Select statement with a where clause and add 'comment' in another column -

-

i need add ‘comment’ in additional column select statement clause.

current code

first statement

select * [table] [dep]        = 'm'      ,                              ([join m]   <> [join b] or                                [resign m]  <> [resign date beneficiary])  go

second statement

select * [table] [join b]   < [resign b]  ,                             ([join m]  > [join b]    or                              [resign m] < [resign b]) go

this 2 different select statements, combine both outputs 1 table.

wrong code - (example explain)

first statement

select * [table] [dep]        = 'm'      ,                              ([join m]   <> [join b] or                                [resign m]  <> [resign date beneficiary])  set [comment] = 'main' go

second statement

select * [table] [join b]   < [resign b]  ,                             ([join m]  > [join b]    or                              [resign m] < [resign b]) set [comment] = 'date' go

the requirement add additional column output , add 'comment' in field, combine both outputs in 1 table.

output

first statement output

 [number] |[dep]  |[join m]  |[join b]  |[resign m ]|[resign b]  10003    |m      |20160101  |20160201  |20160301   |20160301  10004    |m      |20160101  |20160201  |20160301   |20160401

second statement output

 [number] |[dep]  |[join m]  |[join b]  |[resign m ]|[resign b]  10000    |m      |20160201  |20160201  |20160131   |20160430  10002    |m      |20160501  |20160430  |20160430   |20160430

required output

 [number] |[dep] |[join m]  |[join b]  |[resign m ]|[resign b]|[comment]  10000    |m     |20160201  |20160201  |20160131   |20160430  |'date'  10002    |m     |20160501  |20160430  |20160430   |20160430  |'date'  10003    |m     |20160101  |20160201  |20160301   |20160301  |'main'  10003    |m     |20160101  |20160201  |20160301   |20160401  |'main'

use union all combine multiple (compatible) result sets, , can add expressions in select clause

select [number],[dep],[join m],[join b],[resign m ],[resign b],'main' comment [table] [dep]        = 'm'      ,                              ([join m]   <> [join b] or                                [resign m]  <> [resign date beneficiary])  union  select [number],[dep],[join m],[join b],[resign m ],[resign b],'date' comment [table] [join b]   < [resign b]  ,                             ([join m]  > [join b]    or                              [resign m] < [resign b])

alternatively, if these rows represent entire contents of table , want classify rows either main or date, use case expression:

select [number],[dep],[join m],[join b],[resign m ],[resign b],   case when [dep]        = 'm'      ,              ([join m]   <> [join b] or                [resign m]  <> [resign date beneficiary])   'main'   else 'date' end comment [table]

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
