Discoverer Tip : Single Line Comments Causing EUL Export Errors
August 2, 2004
Mark Rittman

Useful Discoverer tip on the OTN Discoverer Forum by Lance Buick:

"In the spirit of sharing.

I recently had some major problems releasing a Discoverer EUL through our database release process, using the EUL Export functionality (i.e. creating an .eex file).

I have a large complex Custom Folder in the EUL, comprised of 14 large unioned select statements.

The EUL would seem to import OK into the new database, but a Workbook based on the Custom Folder continually came up with an item dependancy error.

We traced the problem back to the Custom Folder, which was invalid in the Admin Tool, and therefore not visible to the EUL Users - with a workbook based on the offending Custom Folder.

The moral of the story is DO NOT put single line comments "--" in Discoverer Custom Folder SQL queries - especially large queries. The EUL Export process will unformat your queries, and the single line comments will end up inside the valid SQL - which will invalidate it.

Only use block comments "/* Comment */" in your Custom Folders.

Hope this helps someone else save some time."
