sql server - Allow multiselect on a CSV column in SSRS -

-

i trying make parameter multiselect on csv column in report, not sure how or if it's possible. example dataset returned:

|  id  |  name  |      types      | |  1   |  test  |  type a, type b |

the current dataset using in where clause parameter:

where types '%' + @types + '%'

this works fine single select, of course doesn't work multiselect. how can make parameter allow multiple values , still search csv column? wish where types in '%' + @types + '%' work, end where types in ('%type a%, %type b%'). or there better way can display column appears csv if sql not doing it? still want display values , see if selected type in list, if parameter set type b should still show type a, type b id = 1. know csvs disliked in sql, seems frequent thing that's asked make csv columns , allow multiselect on it.

there 2 posibilities (1) filter have single value 'type a' (2) filter have multiple values 'type a, type b' here giving solution both 1 , 2. here have used #table make understand easy

dummy data be:

if object_id('tempdb.dbo.#temp') not null begin     drop table #temp; end  if object_id('tempdb.dbo.#temp') null begin     create table #temp     (          id         int identity(1,1) primary key         ,name       varchar(100)         ,types      varchar(2000)     ) end  insert #temp(name,types) values ('test','type a, type b'), ('test1','type a, type c'), ('test2','type b'), ('test3','type c, type a'), ('test4','type c');  declare  @typefilter        varchar(2000)

posibility 1:

select   @typefilter = 'type c'  select  *    #temp t (nolock)   (',' + t.types + ',') ('%,' + @typefilter + ',%')

posibility 2:

select   @typefilter = 'type c, type b'  select  distinct         t.*    #temp t (nolock)         join dbo.udf_getsplitvalues(@typefilter,',') p on (',' + t.types + ',') ('%,' + p.stitems + ',%')

here posibility 2, have used table-value function returns csv values table , applied join primary table.

hope helpful.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
