Question

嘿大家我刚刚来到这里以及php只用了大约2个月就有点学习了。我现在需要做的是从数据库中的大约16个不同的表中获取数据并复制表。该表适用于申请人，并且要么具有共同的应用程序ID，要么具有共同的家庭ID，id是刚刚生成的哈希值。我现在正在做的是单独擦除每个表，然后使用数据进行插入，只需更改应用程序ID和/或id。有些桌子非常大，我试图想出一个更容易更快的方法来做这个，这是我为我的一张桌子写的一个例子。

Answer 1

您不需要循环所有行用这个：

Insert into new_table select * from old_table where {your criteria here}

Answer 2

mysql有INSERT into table (fields,list) SELECT fields,list FROM another_table语法

Answer 3

你可以这样做：

INSERT INTO family ( appliction_id, all_the_other_fields )
SELECT 'your_new_app_id', all_the_other_fields  
FROM familY
WHERE familyID='$famid' AND applicationID='$appid'

让我们希望您的$ famid和$ appid变量被转义，是吗？

Answer 4

您可以使用mysql_fetch_assoc()而不是数组来减少SELECT端的PHP代码量，尤其是因为您只需将返回的数组块重新分配给各个变量：

$query = "SELECT Fam_Type, Fam_Title, Fam_SSNI20, Fam_SSNI20_Select etc... etc...";
$resultC = mysql_db_query($aidDB, $queryC, $connection); echo $queryC;
while($rC = mysql_fetch_assoc($resultC)) {
   ...
}

此时，您最终得到了相关数组，您可以将其作为单个值获取：

echo "Fam_Type is " . $rc['Fam_Type'];
echo "Fam_Title is " . $rc['Fam_Title'];

可以为您节省大量的变量赋值。当然，如果查询中的任何字段内部映射到相同的名称（例如，您正在进行连接并从两个不同的表中检索两个不同的“id”字段），那么您需要对它们进行别名对于不同的名称，所以它们在数组中明显地出现，但这是查询的简单模型：

SELECT table1.id AS table1_id, table2.id AS table2_id ...

将留给：

$result['table1_id'] = ...

作为辅助节点，您应该始终检查查询是否成功。你盲目地认为它有效并尝试检索数据。但是如果查询失败，则mysql函数返回FALSE，这将不是有效的结果语句并且会中断您的获取尝试。至少，添加一些基本的错误检查

$resultC = mysql_db_query(...) or die("MySQL error: " . mysql_error());

将吐出错误消息并解释查询失败的原因，而不是稍后失败的“...不是有效的语句句柄”。同样，从PHP 5.3开始，mysql_db_query()已被弃用，并且在将来的PHP版本中将会消失。可能希望切换到常规mysql_query()。
