1、安装

  进入SQLite Download Page页面，下载sqlite-dll-win-x86-*.zip、sqlite-amalgamation-*.zip、sqlite-tools-win-x64-*.zip三个包，这三个包里分别包含dll文件和def文件、头文件、exe工具。

  使用vs命令行工具生成.lib文件：进入dll和def文件所在的目录，执行lib /DEF:sqlite3.def /OUT:sqlite3.lib /MACHINE:x86后获得.lib文件，这样就可以通过dll文件、lib文件、头文件来开发SQLite了。

  exe工具可以进行SQLite操作，比如下面为创建数据库和表（输入.quit结束命令，SQL语句以分号结尾）：

2、代码示例

#include <iostream>
#include "sqlite3.h"//SQL语句查询结果回调，比如对于select来说，查询到的每一条数据都会执行callback方法一次
static int callback(void* data/*sqlite3_exec()的第四个参数*/, int argc/*结果的列个数*/, char** argv/*结果字段值*/, char** azColName/*结果列名*/) {for (int i = 0; i < argc; i++) {printf("%s = %s\n", azColName[i], argv[i] ? argv[i] : "NULL");}printf("\n");return 0;
}int main()
{sqlite3* pDB = nullptr;char* zErrMsg = nullptr;const char* sql = nullptr;const char* data = "Callback function called";//打开数据库，不存在则创建int nRes = sqlite3_open("D:\\sqlite\\test.db", &pDB);if (nRes) {fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(pDB));exit(0);}//创建表，已存在则创建失败sql = "create table company("\"id integer primary key autoincrement,"\"name text not null,"\"age integer not null);";nRes = sqlite3_exec(pDB, sql, 0, 0, &zErrMsg);if (nRes != SQLITE_OK) {fprintf(stderr, "SQL error: %s\n", zErrMsg);sqlite3_free(zErrMsg);}//插入数据sql = "insert into company (id,name,age) values(1, 'Paul', 32); " \"insert into company (id,name,age) values (2, 'Allen', 25); " \"insert into company (id,name,age) values (3, 'Teddy', 23);";nRes = sqlite3_exec(pDB, sql, 0, 0, &zErrMsg);if (nRes != SQLITE_OK) {fprintf(stderr, "SQL error: %s\n", zErrMsg);sqlite3_free(zErrMsg);}//查询数据sql = "select * from company";nRes = sqlite3_exec(pDB, sql, callback, (void*)data, &zErrMsg);if (nRes != SQLITE_OK) {fprintf(stderr, "SQL error: %s\n", zErrMsg);sqlite3_free(zErrMsg);}printf("==============================================\r\n");//修改数据sql = "update company set age = 25 where id=1; select * from company";nRes = sqlite3_exec(pDB, sql, callback, (void*)data, &zErrMsg);if (nRes != SQLITE_OK) {fprintf(stderr, "SQL error: %s\n", zErrMsg);sqlite3_free(zErrMsg);}printf("==============================================\r\n");//删除数据sql = "delete from company where id=3; select * from company";nRes = sqlite3_exec(pDB, sql, callback, (void*)data, &zErrMsg);if (nRes != SQLITE_OK) {fprintf(stderr, "SQL error: %s\n", zErrMsg);sqlite3_free(zErrMsg);}sqlite3_close(pDB);
