Mysql同行拷贝 - 同一表120次

Question

Simple mysql table:

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

And inserted like:

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

How can i enter same table detail of one row 100 times with different primary id?

Answer 1

with php you can do it this way:

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`);
 }  

OR
You can also do it with a mysql store procedure like:

//Loop stored procedure

DELIMITER $$
DROP PROCEDURE IF EXISTS test$$
CREATE PROCEDURE test()
BEGIN
 DECLARE count INT DEFAULT 0;
 WHILE count < 119 DO
      INSERT INTO `users` (`name`, `surname`, `city`)   
      VALUES   (`rock`,`fixed`,`london`);
   SET count = count + 1;
 END WHILE;
END$$
DELIMITER ;

execute the stored procedure

call test();

EDIT BASED ON COMMENTS:
Your code is not working because you are executing your query "outside" the loop, you code should look like this:

<?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(); 
?>

Answer 2

try the following code

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`)";
}

Answer 3

Doing it as a single SQL statement with no loop:-

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

The 2 sub queries just return ranges of numbers. With 10 in one and 12 in the other when cross joined they will return in total 120 rows. Those 120 rows are just your fixed values, but with NULL for the id which the auto increment will sort out into a unique value.

Note that you can do larger ranges like this. For example if you wanted to insert 653 rows (just a fairly random choice of number):-

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

Or specifying the id field as the calculated value:-

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

Answer 4

Since the id has the property AUTO_INCREMENT this should generate a unique ID every time you enter data.

So your insert string can be like this:

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

The id field will then auto-increment each time, giving you unique IDs

Answer 5

只需使用此查询：

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