// Test case from Amnon David 11/1/2007
// I've noticed that table schemas in SQLite3 can sometimes have typeless
// columns. One (and only?) example is the sqlite_sequence that sqlite
// creates for autoincrement . Attempting to traverse this table caused
// SOCI to crash. I've made the following code change in statement.cpp to
// create a workaround:
void test4()
{
    {
        // we need to have an table that uses autoincrement to test this.
