Hi all.
I have a simple query I hope someone can help this poor newbie with...
2 tables:
_______________________ _____________________
| DOCUMENT | | LIBRARY COPY |
|=====================| |===================|
| DOCUMENT_ID |<------------| DOCUMENT_ID |
|---------------------| |-------------------|
| TITLE | | COPY_ORDER |
|---------------------| |-------------------|
| BLAH BLAH BLAH | | LIBRARY_ID |
|---------------------| |___________________|
| ETC.... |
My problem is this...
There may be several copies of a document stored at different libraries. I need to create a column that replaces LIBRARY_ID if a document IS in multiple libraries and populate all the library ID's in that column instead of listing the same document many times with a different library ID each time.
I have been trying a WHERE EXISTS clause but can't get it running.
Thank you for your help,
Justin. Received on Wed Oct 08 1997 - 00:00:00 CEST
