php数据库问题
php数据库,我一般都是直接在PhpMyAdmin中直接按到处数据,就直接复制那些内容到sql文件,不过导入的时候要自己先弄一个数据库,才可以导入那个sql文件,如果没有事先自己弄一个数据库,它会提示没有这个数据库,请问有什么办法导出数据库再重新导入的时候不用自己先创建数据库的呢?求请教,谢谢


------解决方案--------------------
在导出的 SQL 文件的开始处加上这两行
create if not extists database 库名;
use 库名;


其实 PhpMyAdmin 没有给 SQL 文件加上这两行是很人性化的
1、把表导入到哪个库,由导入者决定。可防止导错了地方
2、所有租用的空间都是不能自己设置库名的,大多也没有创建数据库的权限
------解决方案--------------------
编辑你的sql文件,在前面写入
create database xxxx;
use xxxx;
............

保存后再导入。
