What's wrong with this query?

[jda]

The following REGEX search isn't working, although the text *is* 
present in a textfield.


SELECT id,uniqueID from thetable WHERE url REGEX 
'http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Citation&list_uids=1406972' 


I've run this through Valentina.escape, but that doesn't do anything 
(no blackslashes in the query).

Can someone tell me what's wrong with the query?

Thanks,

Jon
