Hmm bad news.
If so, it may be better to use the sequence like the following for example.
char *query_ptr;
size_t bufsize_res;
int slen;
/* Initialize */
query_ptr = columns_query;
bufsize_res = sizeof(columns_query);
if (..)
{
if ((slen = snprintf(query_ptr, bufsize_res, .., )) <= 0)
{
.. error_handling ..
}
query_ptr += slen;
bufsize_res -= slen;
}
...
