Php Mysql同一行复制同一表120次

简单mysql表：

CREATE TABLE  `users` (
 `id` INT NOT NULL AUTO_INCREMENT ,
 `name` TEXT NOT NULL ,
 `surname` text NOT NULL ,
 `city` text NOT NULL ,
PRIMARY KEY (  `id` )
) ENGINE = MYISAM

并插入如下内容：

INSERT INTO `users` (`id`, `name`, `surname`, `city`) VALUES (1,`rock`,`fixed`,`london`);

如何使用不同的主id将同一行的表详细信息输入100次？

由于id具有“自动增量”属性，因此每次输入数据时都应生成一个唯一的id

因此，插入字符串可以如下所示：

INSERT INTO `users` (`name`, `surname`, `city`) VALUES (`rock`, `fixed`, `london`);

---

id字段将每次自动递增，为您提供唯一的id。使用php，您可以这样做：

for($i=0; $i< 119; $i++)
{
     //execute your query here, do not include your id column
     INSERT INTO `users` (`name`, `surname`, `city`)   
     VALUES   (`rock`,`fixed`,`london`);
 }  

根据评论进行编辑： 您的代码无法工作，因为您正在循环外执行查询，您的代码应该如下所示：

<?php 

*/here mysql connection 
for($x=0; $x<100; $x++) 
{ 
   $sql =INSERT INTO users (name, surname, city) 
          VALUES (rock,fixed,london); 
   $status = $conn->query($sql);
} 

if ($status) 
{  echo "New record created successfully"; }
else { echo "Error: " . $sql . "<br>" . $conn->error; } 
$conn->close(); 
?>

只需使用以下查询：

INSERT INTO users ( name, surname, city) VALUES ('rock','fixed','london');

---

请尝试以下代码

for ($i=0; $i<= 119; $i++){
      //exclude id and do auto increament and primary key
       $qry = "INSERT INTO `users` (`name`, `surname`, `city`) VALUES (`rock`,`fixed`,`london`)";
}

---

将其作为没有循环的单个SQL语句执行：-

INSERT INTO `users` (`id`, `name`, `surname`, `city`) VALUES (1,`rock`,`fixed`,`london`);
SELECT NULL, `rock`, `fixed`, `london`
FROM
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) units
CROSS JOIN
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 UNION SELECT 10 UNION SELECT 11
) tens

这两个子查询只返回数字的范围。交叉连接时，一个10行，另一个12行，总共返回120行。这120行只是您的固定值，但id为NULL，自动递增将其排序为唯一值

请注意，您可以这样做更大的范围。例如，如果您想插入653行，只需相当随机的数字选择：-

SELECT NULL, `rock`, `fixed`, `london`
FROM
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) units
CROSS JOIN
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 
) tens
CROSS JOIN
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 
) hundreds
WHERE (units.aCnt + 10 * tens.aCnt + 100 * hundreds.aCnt) < 653

或将id字段指定为计算值：-

SELECT 1 + units.aCnt + 10 * tens.aCnt + 100 * hundreds.aCnt, `rock`, `fixed`, `london`
FROM
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) units
CROSS JOIN
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 
) tens
CROSS JOIN
(
    SELECT 0 AS aCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 
) hundreds
WHERE (units.aCnt + 10 * tens.aCnt + 100 * hundreds.aCnt) < 653

在insert查询中删除id列和相应的值。在用户名、姓氏、城市值中插入“rock”、“fixed”、“london”；好的，现在我如何复制同一行100次，我需要复制数据100次吗？或者一些小技巧？循环它。对于$x=0$x@Purohit您想添加记录120次还是100次？这个答案和你的答案是一样的@luthandolook，现在我如何复制同一行100次，我需要复制100次数据吗？还是一些小技巧？@LuthandoLoot的答案告诉你如何在PHP中执行for循环，使用它在PHP中插入100行，而不是按照我的要求输入100次或120次，每次执行时只需输入1次行。我使用了代码：–我使用php类型的任何方式，但在mysql中，它显示：1136-列计数与php中第1行的值计数不匹配。使用它时，没有按照我的要求输入100次或120次，每次执行时只需输入1个时间行。我使用了代码：–@Purohit这是因为您在循环外执行查询，请将if语句移到循环内loop@Purohit检查我编辑的答案，一切正常，@感谢您的解释。这可能比从php中分别插入120个插件要快得多。
