首先，把编译SQLITE生成的DLL、LIB和sqlite3.h 放到项目的文件夹下，把项目=》属性=》链接器=》输入=》附加依赖项：输入SQLITE的lib文件名

一、创建MySQLite.cpp：

#include "stdafx.h"

#include "MySQLite.h"

bool MySQLite::sqlite_connect(char *filename)

{

    db=NULL;

    zErrMsg = 0;

    row = 0, column = 0;

    int rc;

    rc = sqlite3_open(filename, &db); //打开指定的数据库文件,如果不存在将创建一个同名的数据库文件

    if( rc )

    {

        strcpy(zErrMsg,sqlite3_errmsg(db));//保存错误信息

        sqlite3_close(db);

        return false;

    }

    return true;   

}



bool MySQLite::sqlite_exec(char *sql)

{

    int rc;

    rc=sqlite3_exec( db , sql , 0 , 0 , &zErrMsg );

    if(rc == SQLITE_OK)

        return true;

    return false;

}



void MySQLite::sqlite_search(char *search_sql)

{

    sqlite3_get_table( db,search_sql,&azResult,&row,&column,&zErrMsg);

}



bool MySQLite::sqlite_disconnect()

{

//释放掉 azResult 的内存空间

    sqlite3_free_table( azResult );

    if(sqlite3_close(db)==SQLITE_OK) //关闭数据库

        return true;

    return false;

}



二、创建MySQLite.h：

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include "sqlite3.h"

class MySQLite

{

private:

    sqlite3 *db;//数据库句柄

    char **azResult; //二维数组存放结果

    char *zErrMsg;//保存错误信息

    int row;

    int column;

public:

    bool sqlite_connect(char *filename);//连接数据库

    bool sqlite_exec(char *sql);//执行SQL命令

    void sqlite_search(char *search_sql);//查询

    bool sqlite_disconnect();//断开数据库连接



    int GetTableRow(){return row;}//查询后，取得表“列”数

    int GetTableColumn(){return column;}//查询后，取得表“栏”数

    char *GetErrorMsg(){return zErrMsg;}//取得当前错误提示

    char *GetTableData(int x,int y){return *(azResult+x+y*column);}//查询后，取得表内某个单元值

};



三、创建测试文件test.cpp：



#include "stdafx.h"

#include <iostream>

#include "MySQLite.h"

#define _DEBUG_

using namespace std;

int main( void )

{

    bool result;

    MySQLite *sqlite=new MySQLite();

    result=sqlite->sqlite_connect("hellogv.db");

    if(!result) cout<<sqlite->GetErrorMsg()<<endl;

   

    result=sqlite->sqlite_exec("CREATE TABLE SensorData(ID INTEGER PRIMARY KEY,SensorID INTEGER,SiteNum INTEGER,Time VARCHAR(500),SensorParameterREAL);");

    if(!result) cout<<sqlite->GetErrorMsg()<<endl;



    result=sqlite->sqlite_exec("INSERT INTO \"SensorData\" VALUES(NULL , 1 , 1 , '200605011206', 18.9 );");

    if(!result) cout<<sqlite->GetErrorMsg()<<endl;





    result=sqlite->sqlite_exec("INSERT INTO \"SensorData\" VALUES(NULL , 23 , 45 , '200605011306', 16.4 );");

    if(!result) cout<<sqlite->GetErrorMsg()<<endl;



    sqlite->sqlite_search("SELECT * from SensorData");

    cout<<sqlite->GetTableColumn()<<"   "<<sqlite->GetTableRow()<<endl;

    cout<<sqlite->GetTableData(0,0)<<endl;



    sqlite->sqlite_disconnect();



    return 0;

}
