Bug #26549	Table aliases for constants return an error when using a function in order by cl

Status:	Unsupported	Impact on me:	None
Category:	MySQL Server	Severity:	S3 (Non-critical)
Version:	5.0.11	OS:
Assigned to:		CPU Architecture:	Any

Description:
Selecting a constant value and using a table alias and attempting to use a function in order by clause returns an unknown column error.

How to repeat:
The following statements work as expected:
select 'bug' as `foo` order by `foo` asc
select 'bug' as `foo` order by length(1) asc
select 'bug' as `foo` order by `foo` asc

The following statement returns "Unknown column `foo` in order by clause"
select 'bug' as `foo` order by length(`foo`) asc

Thank you for taking the time to report a problem.  Unfortunately you are not using a current version of the product you reported a problem with -- the problem might already be fixed (i couldn't reproduce it with current 5.0 source). Please download a new version from http://www.mysql.com/downloads/

If you are able to reproduce the bug with one of the latest versions, please change the version on this bug report to the version you tested and change the status back to "Open".  Again, thank you for your continued support of MySQL.
