Hi All,
I have a table that's described as follows:
++---+--+-+---++
| Field | Type | Null | Key | Default |
Extra |
++---+--+-+-

roughly does the same thing:

SELECT DateCreatedField
FROM my_table
ORDER BY DateCreatedField DESC
LIMIT 10;

ORDER BY DateCreatedField DESCENDING
Does MySQL no

Dear all,
I have a table Kids which has the following fields:
kid char(20),
favorite_fruits set('apple','pear','orange',)
favorite_fruits has choices of up to 64 items.

Hello Guys,
I have a char field, and I'd like to have select ordering it by lowercase
caracteres, uppercase caracters then special characters. I was reading about sort and
this seems to be related to charset of the server, and I dont have access to change
