SQLite C++ Wrapper 是一个 C++ 语言对 SQLite 的最小封装包。

示例代码1：

 

#include <string>

#include <iostream>

#include <stdexcept>

using namespace std;

 

#include "sqlite3x.hpp"

using namespace sqlite3x;

 

int main(void) {

try {

sqlite3_connection con("test.db");

 

int count = con.executeint(

"select count(*) "

"from sqlite_master "

"where name='t_test';");

 

if(count == 0) {

con.executenonquery(

"create table t_test(number,string);");

}

 

sqlite3_transaction trans(con);

{

sqlite3_command cmd(con,

"insert into t_test values(?,?);");

cmd.bind(2, "foobar", 6);

 

for(int i = 0; i < 10000; ++i) {

cmd.bind(1, i);

cmd.executenonquery();

}

}

 

// if trans goes out of scope (due to an exception or

// anything else) before calling commit(), it will

// automatically rollback()

trans.commit();

}

catch(exception &ex) {

cerr << "Exception Occured: " << ex.what() << endl;

}

 

return 0;

}
