[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5539) ParameterParser does not support escaped ' symbols

[Chris Morris (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39630#action_39630 ] 

Chris Morris commented on HHH-5539:
-----------------------------------

No, there is a defect in the escaping of string values.

createSQLQuery(sql).list() fails to find a match, if the SQL is
   select screen.name as screenname from HOLD_ABSTRACTHOLDER as screen where screen.name = 'Hampton Additive + HT';
If I update the database to remove the "+" and change the query, the record is found.

I don't understand why Hibernate is processing this at all - the query works find in psql.

> Looks like ParameterParser incorrectly process queries with escaped ' symbol. For example query like "select * from a where a.b = 'asdf \' asdf'" works fine, but "select * from a where a.b = 'asdf \' asdf: '" fails with 
> org.hibernate.QueryException: Space is not allowed after parameter prefix ':' 'select * from a where a.b = 'asdf \' asdf''
