sqlite在c++中的使用方法

1.需要下载的文件      http://pan.baidu.com/s/1c06NpzM

2.执行文件shell的编译

3.在c++中如何使用

#include <stdio.h>
#include <sqlite3.h>
 
static int _sql_callback(void *notused, int argc, char **argv, char **szColName)
{
    int i = ;
 
    printf("notused:0x%x, argc:%d\n", notused, argc);
    for (i = ; i < argc; i++)
    {
        printf("%s = %s\n", szColName[i], argv[i] ==  ? "NULL" : argv[i]);
    }
    printf("\n");
 
    return ;
}

int main(int argc, char** argv)
{
    const char *sSQL1 = "create table users(userid varchar(20) PRIMARY KEY, age int, birthday datetime);";
    const char *sSQL2 = "insert into users values('wang', 20, '1989-5-4');";
    const char *sSQL3 = "select * from users;";
 
    sqlite3 *db = ;
    char *pErrMsg = ;
    int ret = ;
 
    //连接数据库
    ret = sqlite3_open("./test.db", &db);
    if (ret != SQLITE_OK)
    {
        fprintf(stderr, "无法打开数据库：%s\n", sqlite3_errmsg(db));
        sqlite3_close(db);
        return ;
    }
    printf("数据库连接成功\n");
 
    //执行建表SQL
    ret = sqlite3_exec(db, sSQL1, _sql_callback, , &pErrMsg);
    if (ret != SQLITE_OK)
    {
        fprintf(stderr, "SQL create error: %s\n", pErrMsg);
        sqlite3_free(pErrMsg); //这个要的哦，要不然会内存泄露的哦！！！
        sqlite3_close(db);
        return ;
    }
    printf("数据库建表成功！！\n");
 
    //执行插入数据
    ret = sqlite3_exec(db, sSQL2, _sql_callback, , &pErrMsg);
    if (ret != SQLITE_OK)
    {
        fprintf(stderr, "SQL insert error: %s\n", pErrMsg);
        sqlite3_free(pErrMsg); //这个要的哦，要不然会内存泄露的哦！！！
        sqlite3_close(db);
        return ;
    }
    printf("数据库插入数据成功！\n");
 
    //执行查询操作
    ret = sqlite3_exec(db, sSQL3, _sql_callback, , &pErrMsg);
    if (ret != SQLITE_OK)
    {
        fprintf(stderr, "SQL error: %s\n", pErrMsg);
        sqlite3_free(pErrMsg);
        sqlite3_close(db);
        return ;
    }
    printf("数据库查询成功！！\n");
 
    //关闭数据库
    sqlite3_close(db);
    db = ;
 
    return ;
}
