我试图创建在C++中使用sqlite3的lib ..我得到错误sqlite3_prepare_v2'
数据库如图logcat的没有在此范围声明。C++:用于插入创建使用SQLite数据库和更新
日志文件
..\src\Test.cpp: In function 'int main(int, const char**)':
..\src\Test.cpp:21:85: error: 'sqlite3_prepare_v2' was not declared in this scope
..\src\Test.cpp:30:13: error: variable 'sqlite3 in' has initializer but incomplete type
..\src\Test.cpp:30:30: error: invalid use of incomplete type 'sqlite3 {aka struct sqlite3}'
..\src\/sqlite3.h:73:16: error: forward declaration of 'sqlite3 {aka struct sqlite3}'
这里是我的代码
#include <iostream>
using namespace std;
#include "sqlite3.h"
int main (int argc, const char * argv[]) {
sqlite3 *db;
sqlite3_open("test.db", & db);
string createQuery = "CREATE TABLE IF NOT EXISTS items (busid INTEGER PRIMARY KEY, ipaddr TEXT, time TEXT NOT NULL DEFAULT (NOW()));";
sqlite3_stmt *createStmt;
cout << "Creating Table Statement" << endl;
sqlite3_prepare_v2(db, createQuery.c_str(), createQuery.size(), &createStmt, NULL);
cout << "Stepping Table Statement" << endl;
if (sqlite3_step(createStmt) != SQLITE_DONE) cout << "Didn't Create Table!" << endl;
string insertQuery = "INSERT INTO items (time, ipaddr) VALUES ('test', '192.168.1.1');"; // WORKS!
sqlite3_stmt *insertStmt;
cout << "Creating Insert Statement" << endl;
sqlite3_prepare(db, insertQuery.c_str(), insertQuery.size(), &insertStmt, NULL);
cout << "Stepping Insert Statement" << endl;
if (sqlite3_step(insertStmt) != SQLITE_DONE) cout << "Didn't Insert Item!" << endl;
cout << "Success!" << endl;
return 0;
}
请帮助我。谢谢.....
