在抛出"std：：__cxx11：：basic_string<char、std：：char_traits<char>、std：：分配器<char>>"的实例后调用终

Question

我尝试编写一个示例项目来使用sqlite。每次输入 ID 时，都会收到以下错误消息： 在抛出"std：：__cxx11：：basic_string， std：：分配器>"的实例后终止调用

谁能帮我？

Header Database.h

...
private:
void showMenu();
void addRecord();
void showRecord();
void openDB();
int nSelection;
sqlite3* db;
int rc;
std::string sql;
const unsigned char* uc_result_firstName;
const unsigned char* uc_result_lastName;
int nRowID;
std::string strFirstName;
std::string strLastName;
int nAge;

}; ...

cpp 文件数据库.cpp

...
void Database::showRecord(){
std::cout << "Select ID -> ";
int nID;
std::string strBuffer = "";
std::cin >> strBuffer;
nID = std::stoi(strBuffer.c_str());
sqlite3_stmt* stmt;
rc = sqlite3_prepare_v2(db, "SELECT FirstName, LastName, Age"
" FROM customerTable"
" WHERE id = ?", -1, &stmt, NULL);
if (rc != SQLITE_OK)
throw std::string(sqlite3_errmsg(db));
rc = sqlite3_bind_int(stmt, 1, nID);            // Using parameters ("?") is not
if (rc != SQLITE_OK) {                          // really necessary, but recommended
std::string errmsg(sqlite3_errmsg(db));     // (especially for strings) to avoid
sqlite3_finalize(stmt);                     // formatting problems and SQL
throw errmsg;                               // injection attacks.
}
rc = sqlite3_step(stmt);
if (rc != SQLITE_ROW && rc != SQLITE_DONE) {
std::string errmsg(sqlite3_errmsg(db));
sqlite3_finalize(stmt);
throw errmsg;
}
if (rc == SQLITE_DONE) {
sqlite3_finalize(stmt);
throw std::string("customer not found");
}
uc_result_firstName = sqlite3_column_text(stmt, 0);
uc_result_lastName = sqlite3_column_text(stmt, 1);
this->nRowID     = nID;
this->strFirstName = std::string(reinterpret_cast<char const*>(uc_result_firstName));
this->strLastName  = std::string(reinterpret_cast<char const*>(uc_result_lastName));
this->nAge         = sqlite3_column_int(stmt, 2);
sqlite3_finalize(stmt);
std::cout << "nLastname: " << strLastName << std::endl;

}

我认为您缺少编译标志

-std=c++11
