sql - Add sequence number to query results -


i using access 2010 process student discipline information data.

for incidents there multiple offenders. in source data each offender has own row. need query return offender number (1, 2, 3) involved in incident.

the data in single table each row has unique key tying rest of database.

source table:

incidentid_uk    |    personid_uk    |   uniquekey  ------------------------------------- 3001             |    1234           |    1 3002             |    1235           |    2 3002             |    1236           |    3 3002             |    1237           |    4 3003             |    1238           |    5 3004             |    1239           |    6 3005             |    1234           |    7

desired result: 

incidentid_uk    |    personid_uk    |    sequence ------------------------------------- 3001             |    1234           |    1 3002             |    1235           |    1 3002             |    1236           |    2 3002             |    1237           |    3 3003             |    1238           |    1 3004             |    1239           |    1 3005             |    1234           |    1

in ms access, can information using correlated subquery:

select incidentid_uk, personid_uk,        (select count(*)         table t2         t2.incidentid_uk = t.incidentid_uk ,               t2.personid_uk <= t.personid_uk        ) sequence table t;

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.
