java - Not getting specific data from detail table -


here named query fetch specific track specific user metadata. 

"select t track t left join fetch t.metadata tm t.id= :id , tm.userid = :userid"

in track entity having metadata list @onetomany relationship join table inbetween name = tracks_metadata_join.

//trackmetadata    @onetomany(cascade = cascadetype.all, fetch = fetchtype.lazy, targetentity=trackmetadata.class, orphanremoval = true)    @jointable(name = "tracks_metadata_join", joincolumns = { @joincolumn(name = "track_id",    referencedcolumnname = "id", table = "tracks") }, inversejoincolumns = @joincolumn(    name = "track_metadata_id", referencedcolumnname = "id", table = "tracks_metadata"))    @jsonproperty    private list<trackmetadata> metadata = new arraylist<>();

the result of above query track it's metadata, want track particular metadata. user specific. thanks!

when read track , initialize metadata collection, hibernate populate entire collection. that's how hibernate works.

if want specific metadata elements loaded, make association bidirectional , load desired metadata only:

select tm trackmetadata tm tm.track.id = :id , tm.userid = :userid

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
