mysql不能执行两条insert吗？

$sql = "INSERT INTO typecho_contents( title, created, modified, text, authorId, allowComment, allowPing, allowFeed )VALUES ('秘密#$mimiId', '$mimitime', '$mimitime', '$mimicontent', '1', '1', '1', '1');INSERT INTO typecho_relationships(cid, mid) VALUES ('$mimiId', '1')";

这样就不行，报错提示：Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INSERT INTO typecho_relationships(cid, mid) VALUES ('23', '1')' at line 2

单独一句句写就只执行一句，在数据库直接执行下面这两句则可以成功。

INSERT INTO typecho_contents( title, created, modified, text, authorId, allowComment, allowPing, allowFeed )VALUES ('秘密#23', '147852369', '147852369', '为什么', '1', '1', '1', '1');INSERT INTO typecho_relationships(cid, mid) VALUES ('23', '1')

回复讨论(解决方案)

改成

$sql1=mysql_query("INSERT INTO typecho_contents( title, created, modified, text, authorId, allowComment, allowPing, allowFeed )VALUES ('秘密#$mimiId', '$mimitime', '$mimitime', '$mimicontent', '1', '1', '1', '1')");$sql2=mysql_query("INSERT INTO typecho_relationships(cid, mid) VALUES ('$mimiId', '1')");

就成功了
