php - Query with multiple values in a column -


i have table like:

id     name            children 1      roberto         michael,dia 2      maria           john,alex 3      mary            alexandre,diana

my problem is; want find has child named alex.

i can't use "where children = 'alex'" in sql because have more 1 names in same cells.

so use "where children '%alex%'" - looks smart in same time start alex :( alexandre or want dia result dia , diana :(

how can single alex in data type?

i hope can explain problem terrible english :d

the best solution normalize schema. should have separate table 1 row each child, instead of comma-delimited list. can join table find parent specific child. see @themite's answer example of this.

but if can't reason, can use find_in_set:

where find_in_set('alex', children)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
