I am trying this . I have a table in mysql named "quotes" with columns (id,quote,author) with around 100 rows.
i want to select one quote daily and next day another quote sequentially .
how do i achieve this task. I want to get and display it in my webpage daily one quote.
If your id column is sequential (i.e. no gaps) from x to y, you could use modular arithmetic:
SELECT * FROM quotes WHERE id = x + TO_DAYS(CURRENT_DATE) % (y - x + 1)

I have this table:
Well, When I execute this query:
SELECT * FROM users order by rp_bought desc limit 5
I get no errors but, The username, Raed is in the last place as Raed Has the Most Rp_Bought (1300)
Im Wondering Why is this Problem Occurring.
This would occur if rp_bought were stored as a string rather than as a number. In MySQL you can easily fix this by adding 0:
order by rp_bought + 0 desc
The + 0 is an easy way to convert from a string to a number (with no additional errors occurring).

How can I simulate that my MySQL field is an array, and later with some query to search element in that array ?
In only MySql:
To get the field.
select FIELDNAME from TABLE
To search from that result set:
select FIELDNAME from TABLE where FIELDNAME like '%myvalue%'
The %'s are wild cards. This would return any value with myvalue in it.
Such as:
(amyvalue, bmyvalueb, I<3myvaluecompletely)
If you want this done in some language you need to provide a more verbose and detailed question.

I have a column with values like 24,25,26,27 and
I want to match 24 (or some other number).
I like to do it based on regex don't know how to do?
I want the matching should be clear like 24,25,26 should match with 24 not 243
You can take a look at
FIND_IN_SET
SELECT FIND_IN_SET('24','24,25,26 ');
Note Please don't store vales as comma separated instead normalize
your structure

I have a table that contains a column price with 3600 entries. I need to increase the price column by 9% or multiply the contents of the column price by 1.09 and place the updated price back in the price column. What is the best way to approach this?
Should be pretty straightforward:
Update MyTable Set Price = Price*1.09
