Index in Vertica creation -


i'm trying create index i've error:

sql error [2676] [0a000]: [vertica][vjdbc](2676) error: command create index not supported    [vertica][vjdbc](2676) error: command create index not supported [vertica][vjdbc](2676) error: command create index not supported

is possible create index in vertica (version 7)?

create index idx_name_table_lookup on name_table (field 1, field 2);

my suggestion learn more how vertica works. specifically, read concepts guide. sure read through many of sections in navigator on left side.

the short answer is, there no indexes in vertica. instead, there projections, copies of data sorted, segmented , encoded optimally execute queries.

you may not need create additional projections. not assume (especially new vertica) need create projections match indexes might have had in other dbms.

i create table, populate representative set of data, write queries plan use often... run database designer tool comes vertica in comprehensive mode (subsequently can incremental designs if add new query patterns or change how use table). tend few more steps here, if starting, keep simple.

so, things read on (all in concepts guide mentioned above), in no particular order:

  1. projections
  2. database designer
  3. column stores vs row stores
  4. logical vs physical schemas

and want read how load data, in concepts guide.

good luck!

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.
