perror 28
Error code 28: No space left on device

SQL语句执行错误:SELECT title,gid FROM blog_blog WHERE date Error writing file 'C:\WINDOWS\TEMP\MY9B6F.tmp' (Errcode: 28)

解决方法:

1.释放C:\WINDOWS\TEMP\空间

2.因为原表太大,所以查询时生成的临时表过大,因此出错。
解决办法。重启了mysql,然后加上where分三段查询,避免全表扫描。

测试结果:第一个有用,第二个有道理,没测试过,过了第一个就解决了,第二个以后好好研究下
