C++/SQLite only outputting one row of data - c++

Question

I'm having an issue where only one of my 5 test rows will output in C++. My code is:
#include <cstdio>
#include <sqlite3.h>
#include <windows.h>
#include <wincrypt.h>
#include <string>
#include <vector>
#include <iostream>
using namespace std;
/*Definitions*/
sqlite3 *db;
void *arg;
char *err;
const char* stmt = "SELECT * from table";
/*End of Definitions*/
int exec(void *arg, int argc, char **argv, char **column) {
int i;
for(i = 0; i < argc; i++) {
cout << column[i] << ": " << argv[i] << endl;
}
cout << "------" << endl;
}
int main() {
int rc = sqlite3_open("test.sqlite", &db); /*Open db "test.sqlite"*/
if(!rc) {
while(true) {
sqlite3_exec(db, stmt, exec, arg, &err);
if(err) {
break;
}
}
}
/*Ending Stuffz (NOTHING BEYOND THIS POINT)*/
cin.get();
return 0;
}
I am not getting any errors; it is purely just outputting the first row. Any help is appreciated, thanks.

Answer 1

Just return 0 in the end of exec function
Explanation:
In function 'exec" when it return nothing, the database server acts like the function is terminated by somehow (like something corrupt the function and made an error) so it just stop sending data because the call back function terminated with an error.... so when we return 0 we say that the function "exec" is working normally so it keeps sending data ... and if you return any other integer it will deal with it like the function terminated by an error and stop sending data. I faced the same issue and I solved it by making the callback function (exec) return 0.
