BigQuery query from a nested field -


i have table nested field externalids.value

i want run query 2 entries match values in field. here query have, doesn't return data.

select keyfield, field2, example.field1, example.field2, externalids.type, externalids.value (flatten([dataset1.table1], externalids)) externalids.value = '157' , externalids.value = 'some test data' ;

if run query 1 clause (externalids.value = '157') , run query keyfield = "the value returned previous query", 2 lines. 1 showing externalids.value '157' , result 'some test data'.

i'm not interested in displaying both values in result. priority keyfield .value '157' , 'some test data'

maybe that:

select keyfield, field2, example.field1, example.field2, externalids.type, externalids.value [dataset1.table1] omit record if not(   some(externalids.value = '157') ,   some(externalids.value = 'some test data'))

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.
