Hi,
My code to append c_kinhdo2 to c_kinhdo :
ibis::part*tbl = new ibis::part("c:\\DB\\1mil\\2011_12_21_10_50_01",
static_cast<const char*>(0));
ibis::column *c_kinhdo = tbl->getColumn("kinhdo");
ibis::part*tbl2 = new ibis::part("c:\\DB\\1mil\\2011_12_21_14_03_36",
static_cast<const char*>(0));
ibis::column *c_kinhdo2 = tbl2->getColumn("kinhdo");
const char* dt = "c:\\DB\\1mil\\2011_12_21_10_50_01\\KinhDo";
const char* df = "c:\\DB\\1mil\\2011_12_21_14_03_36\\KinhDo";
const uint32_t nold = c_kinhdo->elementSize();
const uint32_t nnew = nold + c_kinhdo2->elementSize();
uint32_t nbuf = 1024;
char* buf = new char[1024];
/// Append new data in directory df to the end of existing data in dt.
c_kinhdo->append(dt, df, nold,nnew, nbuf, buf);
But it doesn't work. Please show me why or another way to append column.
Thanks for help.
Regards,
