Ok to make it work I had to replace

for (irow=0; irow<nrows; irow++)

BUNappend(tmp1, &v_long[irow], FALSE);

with

memcpy(Tloc(tmp1, BUNlast(tmp1)), v_long, nrows*sizeof(long long));

BATsetcount(tmp1, BATcount(tmp1) + nrows);

Hi there,

Is there a way to append an array of values to a BUN, instead one value at a time?

sql_table *tbl = mvc_bind_table(m, sch, "atable");
sql_column *col = mvc_bind_column(m, tbl, "acolumn");
BAT *tmp1 = COLnew(0, TYPE_lng, (BUN)nrows, TRANSIENT);
long long v_long[3] = {100000000009,100000000010,100000000011};

for (irow=0; irow<nrows; irow++)

BUNappend(tmp1, &v_long[irow], FALSE);

mvc_append_column(m->session->tr, col1, tmp1);
mvc_commit(m, 0, tr->name);

bat_destroy(tmp1);

Thanks,
Anton
