当然可以去PHPMYADMIN里浏览一下。但是终究有遗漏吧。所以自己写了个,比较数据库差异的脚本(PHP的),方便一下自己。当然代码很简单,就不讲解了,贴代码:
复制代码 代码如下:

mysql_connect('localhost','root','root');
mysql_select_db('tablea'); //标准的数据库
$q = mysql_query("show tables");
while($s = mysql_fetch_array($q)){
$name = $s[0];
$q1 = mysql_query("desc $name");
while ($s1 = mysql_fetch_array($q1)) {
$a[$name][] =$s1[0];
}
}
mysql_close();
mysql_connect('localhost','root','root');
mysql_select_db('tableb');//需要比较的数据库
$q2 = mysql_query("show tables");
while($s2 = mysql_fetch_array($q2)){
$name2= $s2[0];
$q3 = mysql_query("desc $name2");
while ($s3 = mysql_fetch_array($q3)) {
$aa[$name2][] =$s3[0];
}
}
mysql_close();
$f = $e = array();
$str = $fuhao ='';
foreach($a as $k=>$v){
if(!is_array($aa[$k])){
$e[] = $k;
}
else{
if(count($aa[$k]) count($v)){
foreach($v as $k1=>$v1){
if(!in_array($v1,$aa[$k])){
$f[$k][] = $v1;
}
}
}
}
}
echo "

"; <br>print_r($e);//缺少表 <br>print_r($f);//缺少表的字段 <br>?> <br>
