EXCEL IQY Queries

[Raj]

I have created the Excel iqy queries from the third party
reporting tools and during the process there is an option
either to pass the User Login id and Pass word as a
parameter or not. We have developed some queries using
generic id so that the users do not have to pass the Login
id and password and now we want to change that. Is there a
way to modify that excelquery.iqy file without redoing
that.

can i see the sql script of that "iqy" file.
can i modify that?

Please let me know.

Thanks in advance!!!!
