php - MySQL select where constant is in array in table -


this question has answer here:

hello stackoverflow community,

i have question regarding best method (in terms of resources/speed/etc.) find defined valued in imploded string stored in cell in database.

ie: (all elements in table either int or string)

id | age | name | groups ========================= 0  | 28  | bob  | 1,2,3,4 1  | 33  | sara | 1,4

given requested group 2, best select users , iterate through groups manually see if matches 2. (which doesn't sound resourceful @ all)

or there way constant in array query via mysql

select * tableusers 2 in groups

which select user id 0.

^ won't work there similar alternative?

its easy. can this:

select * tableusers find_in_set(2,groups);

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
