MySql 选择具有开始和条件的特定行数

Question

I want to select a specific count of rows from MySql from an specific startpoint, with a condition. The startpoint should be a variable. My problem is that I dont have the row where to start.

In Words: "Start after the first 5 rows where "status" is equals 1 and give me from there the next 5 rows whith "status" equals 1".

Example Data:

-----------------------
| id | title | status |
-----------------------
| 1  | Test  |    1   |
| 2  | Test  |    0   |
| 3  | Test  |    1   |
| 4  | Test  |    0   |
| 5  | Test  |    1   |
| 6  | Test  |    1   |
| 7  | Test  |    0   |
| 8  | Test  |    1   |
| 9  | Test  |    1   |
| 10 | Test  |    1   |
| 11 | Test  |    1   |
| 12 | Test  |    1   |
| 13 | Test  |    0   |
| 14 | Test  |    1   |
| 15 | Test  |    0   | 

First Case

I want five rows with status equals 1, started at the beginning. (The start variable is 0).

Expected Data:

-----------------------
| id | title | status |
-----------------------
| 1  | Test  |    1   |
| 3  | Test  |    1   |
| 5  | Test  |    1   |
| 6  | Test  |    1   |
| 8  | Test  |    1   |

Second Case

Now I need the next 5 rows where status is equals 1. (The start variable is 5).

Expected Data:

-----------------------
| id | title | status |
-----------------------
| 9  | Test  |    1   |
| 10 | Test  |    1   |
| 11 | Test  |    1   |
| 12 | Test  |    1   |
| 14 | Test  |    1   |

How can i achieve this?

Answer 1

Use the LIMIT clause. The first parameter is the index in the complete result set from where you want to start receiving results. The second parameter is the number of results you want. So to get the first 5 results:

SELECT * FROM my_table WHERE status = 1 ORDER BY id LIMIT 0,5

To get the next 5:

SELECT * FROM my_table WHERE status = 1 ORDER BY id LIMIT 5,5

And so on. Also see here: http://dev.mysql.com/doc/refman/5.5/en/select.html
