php mysql limit doesnt work

Question

I am telling my sql script to generate this:

       $result=mysql_query("SELECT comment_id FROM comments WHERE thread_id=38 LIMIT 2,7");

I dont know why it happens, but it returns to me 7 comments (posts/results) rather than 5.

is my statment is wrong? or is it because when I refresh the page more html is added in addition to the previous html ..?

Answer 1

The clause Limit X, Y included at the end of the select query means X is the starting point (remember the first record is 0 ) and Y is the number records to display.

To get 5 records starting from 2nd record you have to specify: limit 2,5 .

Answer 2

Second argument should be count, not last element. (2,5) in your case

Answer 3

Use this:

$result = mysql_query("SELECT comment_id FROM comments WHERE thread_id=38 LIMIT 2,5");
// Maybe you want to use (0,5) instead!?

Examples

SELECT * FROM `your_table` LIMIT 0, 10 
// This will display the first 10 results from the database.

SELECT * FROM `your_table` LIMIT 5, 5
// This will show records 6, 7, 8, 9, and 10

Answer 4

By your example everything correct.

MySQL Limit first value telling from what row need to start, and the second value how much result need to return.

SELECT comment_id FROM comments WHERE thread_id=38 LIMIT 5

Will return first 5 rows
