My example is taken directly from the test6
void test6()
{
{
session sql(backEnd, connectString);
table_creator_for_test6 tableCreator(sql);
for (int i = 0; i != 10; i++)
{
sql << "insert into soci_test(val) values(:val)", use(i);
}
statement st1 = (sql.prepare <<
"update soci_test set val = val + 1");
st1.execute(false);
assert(st1.get_affected_rows() == 10);
statement st2 = (sql.prepare <<
"delete from soci_test where val <= 5");
st2.execute(false);
assert(st2.get_affected_rows() == 5);
statement st3 = (sql.prepare <<
"update soci_test set val = val + 1");
st3.execute(true); // true or false shoudl make no difference,
both should lead to load_one()
assert(st3.get_affected_rows() == 5);
}
std::cout << "test 6 passed" << std::endl;
}
I'm not sure what update it may need.
