将2000自动完成字段记录添加到现有的mysql表中

Question

I have a table named users

fields:

ID INT
First_name VARCHAR
Second_name VARCHAR
National_ID INT

The ID field is an AUTO_INCREMENT.

I need to AUTO_INCREMENT the first 2000 users with just the ID and the other fields remain blank,so that the new users will start at 2001.

Kindly assist.

It's called auto increment, your ID column must be set to auto increment.

ALTER TABLE users AUTO_INCREMENT=2001;

Update

If you wish to actually create those rows (not just set the auto increment value) you can use PHP for this:

for($i=1; $i<=2000; $i++)
{
    $query = 'INSERT INTO users (id) VALUES ('.$i.')';
    //execute this query using your desired PDO or sql extension
}
