mysql only compares first numerical part of string to int column in where -

this more "why" or "any pointers documentations" question. today realised comparison in clause takes first numerical part of string if compared int column. (my own conclusion) for example: select * companies c id = '817m5' will still return companies id = 817. it make sense i'm failing find documented anywhere see if conclusion correct , if there additional things know exact behaviour. where , int type, comparison documentation? where? how called? thanks! this comparison: where id = '817m5' and id integer. so, mysql has compare integer string. well, can't directly. either has convert string number or number string. mysql converts string number, converting leading numeric characters. so, '817m5' becomes 817 . here exact quote: to cast string numeric value in numeric context, not have other use string value though number: mysql> select 1+'1'; -> 2

arrays - How to rotate a binary vector to minimum in Python -

if have arbitrary binary vector (numpy array) in python, e.g. import numpy np vector = np.zeros((8,1)) vector[2,1] = 1 vector[3,1] = 1 this give me binary array 00001100. have 00000000 or 00010100 etc. how make such script when give binary vector input, script gives minimum right-rotated binary numpy array output? few examples: 00010000 --> 00000001 10100000 --> 00000101 11000001 --> 00000111 00000000 --> 00000000 11111111 --> 11111111 10101010 --> 01010101 11110000 --> 00001111 00111000 --> 00000111 10001111 --> 00011111 etc. suggestions / optimized python implementations in mind? =) thank assistance. need local binary pattern implementation =) the fastest way create table first , can use ndarray indexing result, here code: you need create table yourself, code here demo import numpy np np.random.seed(0) #create table def rotated(s): in range(len(s)): s2 = s[i:] + s[:i] if s2[-1] == "1": yi...

optimization - is there a "best way" to short circuit a mysql query -

i have situation i'm assembling query based on user provided criteria , want figure out efficient way this. if have table looks this: int id | varchar phone | varchar email | varchar rfid and user pass in array defines order (and items) they'd user *could this: ["id","email","phone"] or this: ["email"] or this: ["phone","rfid"] or other possible combination of 4 fields. based on receive need user in order in these fields arrived , if find match, don't want keep looking. in other words if input is ["email","rfid","phone"] and db , find user provided email, don't want keep looking see if rfid matches, want return said user. however, if don't find such email, want move on rfid. so, in various tests i've done (mostly playing case statement in where clause) results have been terrible. taking second return value, opposed taking <50ms when sim...
