问题
Often, sorting is done with symbols sorted to the top, like 0
or *
or &
. This is the default way that mysql sorts; numbers and symbols and then A-Z. However, that makes the often ugliest or most badly formatted results float to the top (e.g. a result of @#$@3423
or 8 inch
or &
).
So I'd like to do a modified form of that, letters first A-Z, and then special characters last.
How would I go about creating that type of sort? Something in the ORDER BY
clause?

EDIT: Original link is dead. Here is another link which actually explains what is happening better than the first link did:

You might try this
SELECT names FROM your_table ORDER BY names + 0 ASC

Select ...
From ...
Order By Case When Col Like '[0-9]%' Then 1 Else 0 End Asc
, Col
Another solution that would account for special characters:
Select ...
From ...
Order By Case When Col Like '[A-Z]%' Then 0 Else 1 End Asc
, Col

This works for me:
SELECT * FROM `yourTable` ORDER BY `yourDatabase`.`yourColumn` ASC
