MYSQL: How can I create a new row and get the new id without inserting data? -

Normally I get a new ID after entering some data and it creates a new line and returns the new ID . But if I do not want to include any data, I just want to create a new ID and want to get a new ID ... How can I do this?

Update:

Okay this is my problem, the table I wanted to do it in 1 id column only Why? I will explain (we will try) I have another table where each line has its own unique ID variation_id (auto-ink), but each line needs to be tied from the same table to the other ranks. I have another column which is called group_id, I can not be auto ink because it needs to be displayed multiple times, what does it mean to say, what kind of changes should be grouped together. So I have to create a second table with Group_ID as the primary key and auto-ink, so that whenever I need a new group, I can use it to generate new group_id. I think I'm going wrong about it ... so what should I do?

Here's an example:

  create table X (id int Primary key AUTO_INCREMENT);  

Then you can "feed" your table:

  Enter the values ​​in the (id) values ​​(zero); SELECT LAST_INSERT_ID ();

 Тарас Лукавий has another question and the answer is:  
  Create table X (ID int primary key AUTO_INCREMENT, timing timestamp);  
 
 Then you "feed" data with: 
 
  INSERT X (id, time) value (NULL, now ()); SELECT LAST_INSERT_ID ();  
 
 Now, let's check this: 
 
  SELECT * FROM X  
 
 You will see each row automatically ID and timestamp
