Alias in Microsoft Query no longer recognized

I have some Excel 2010 workbooks that connect to an Oracle database. Data is returned via Microsoft Query. The query contains some aliases. The data continues to be returned to the spreadsheet with no errors on update. However, if I try to edit the query, I get the following error message: ORA-923: FROM keyword not found where expected. I've discovered that if I delete the alias, I do not get the error.

At first I thought it had to do with upgrading to a new computer (Windows 7 64bit), but I've tested on older computers in the office and I get the same error.

The code follows:
