Hi,
Should it be possible to do the following but with std::string instead of
int? (Example taken from here -
http://soci.sourceforge.net/doc/release/3.2/statements.html )
// Example 3.
void fill_ids(std::vector<std::string>& ids)
{
for (std::size_t i = 0; i < ids.size(); ++i)
ids[i] = std::to_string(i); // mimics source of a new ID
}
const int BATCH_SIZE = 25;
std::vector<std::string> ids(BATCH_SIZE);
statement st = (sql.prepare <<
"insert into numbers(value) values(:val)",
use(ids));
for (int i = 0; i != 4; ++i)
{
fill_ids(ids);
st.execute(true);
}
In the ODBC backend, it seems to not bind directly to the strings, and at
prepare time it copies the string data into a buffer, which isn't
refreshed. So repeated calls to "execute" inserts the same data again, Is
this a known issue? Or am I doing something wrong?
Thanks
Andy
