 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; }
