modify command failed even if no change occured
hi, i use crystal report 2008 demo edition. I can create new report and preview it but failed when i try to edit my command and save it even though no change happened, the following message box pop up and say that invalid argument provided, more detail is that the alias requested 'Command', contains a combination of characters which is not considered to be valid.

i've seen this error before
once you create a report based on "Add Command" option in CR 2008 , it was with MySQL database.
you create the report run it and preview the data, once you want edit or modify the select statement in "Add Command" option, you get such error like this
Invalid Argument Provided
Details: the alias requested 'Command',Containts a combination of characters which is not considered to be valid
the only scenario i had to solve this issue is to create another command,
