Regular expressions (regex) boolean operator in HQL's where clause: rlike in mysql, regexp_match in informix, ... (regression from hibernate2) ---------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-3404 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3404 Project: Hibernate Core Issue Type: New Feature Components: query-hql Affects Versions: 3.2.6 Reporter: Geoffrey De Smet Hibernate 2 supported the rlike boolean operator (at least for mysql): HB-1034. Hibernate3 currently doesn't. It turns out that most mainstream databases support regular expression patterns (independently from normal like patterns). Mysql: rlike where a.serial rlike '\d*' Informix: regexp_match() where regexp_match(a.serial, '\d*') Oracle: REGEXP_LIKE where REGEXP_LIKE(a.serial, '\d*') There have been several forum posts asking about this feature for hibernate3 btw: http://forum.hibernate.org/viewtopic.php?p=2391395 http://forum.hibernate.org/viewtopic.php?p=2375634 etc
