PHP执行sql语句失败,但同样的语句在MYSQL中可以执行
现在的问题是在同一个数据库中有些表能够查询,有些表查询不了。但是这些语句在mysql中都能正常执行
------解决方案--------------------
一个情况一个情况地检查,LZ可以在PHP那边 组合成SQL语句之后 输出生成的sql语句看看 看看数据在后台是否正常 编码有没问题  再检查下数据库的编码
------解决方案--------------------
同样的sql语句直接在数据库中可以插入?
看下你PHP那边写的SQL语句
------解决方案--------------------
直接echo 一下,看看到底输出的是什么。
------解决方案--------------------
权限没问题,就肯定是你的sql有问题了。
把最终要执行的sql打印出来
------解决方案--------------------
mysql_query($sql) or die(mysql_error());
