Question

I am having trouble finding a solution for this question. Suggest any solution for this question in PHP.

I have a table called test_repeat

id  start   repeater   length     final
 1   20       2           3         50
 2   10       50          4        500

and my query is

SELECT T.id AS ID, T.start AS start, T.repeater AS repeater 
       T.length AS length, T.final AS final
FROM `test_repeater` T
RIGHT JOIN `test_repeater` T2 ON T.id = T2.id 
WHERE T.start>=10 and T2.start*T2.repeater<=300

the result i’m getting is

ID  start  repeater   length    final    
1   20       2          3        50       
2   10       5          12       500    

What I am trying to get is the result in such a way that the each start value is added with the repeater and that makes that value as next raw until the final the conditions apply (please see below)

My dream result will be like this

   ID   start   repeater   length     final
   1     20       2           3         50
   1     22       2           3         50
   1     24       2           3         50
   1     ...      .           .         ...
   1     ...      .           .         ...
   1     50       2           3         50
   2     10       5           4         500
   2     15       5           4         500
   2     20       5           4         500
   2     25       5           4         500
   2     30       5           4         500
   2     35       5           4         500
   2     ...      .           .         ...
   2     ...      .           .         ...
   2     ...      .           .         ...
   2     500      5           4         500

Answer 1

OK. That makes more sense…

 DROP TABLE IF EXISTS test_repeat;

 CREATE TABLE test_repeat
 (id  INT NOT NULL AUTO_INCREMENT PRIMARY KEY
 ,start   INT NOT NULL
 ,repeater   INT NOT NULL
 ,length     INT NOT NULL
 ,final INT NOT NULL
 );

 INSERT INTO test_repeat VALUE
 (1,   20       ,2           ,3         ,50),
 ( 2   ,10       ,5          ,4        ,500);


 DROP TABLE IF EXISTS ints;

 CREATE TABLE ints(i INT NOT NULL PRIMARY KEY);

 INSERT INTO ints VALUES (0),(1),(2),(3),(4),(5),(6),(7),(8),(9);



 SELECT r.id
      , r.start+(r.repeater*(i2.i*10+i1.i)) start
      , repeater
      , length
      , final 
   FROM test_repeat r 
   JOIN ints i1
   JOIN ints i2
  WHERE r.start+(r.repeater*(i2.i*10+i1.i)) BETWEEN r.start AND r.final
  ORDER 
     BY id
      , start;
