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;
}
