Kevin Stembridge commented on HHH-2077:
---------------------------------------

Agreed, its not a major issue because there is a workaround. I was just asking if your plan was to make the constructor public or not. 

My interpretation of your answer is that you do think the change should be made, but correct me if I'm wrong. If so, this issue shoud probably be reopened and downgraded to trivial just so it is at least on the radar.

>      Project: Hibernate3
>         Type: Improvement

>   Components: query-criteria
>     Versions: 3.1.3, 3.2.0 cr1, 3.2.0.cr2, 3.2.0.cr3, 3.2.0.cr4
>  Environment: Hibernate 3.1.3, MySQL, HSQLDB, Oracle
>     Reporter: Tobias Dietl

> Original Estimate: 3 hours
>         Remaining: 3 hours

> Up to now, there is no way of setting the escape sequence to use for string comparisions with like for Criteria queries. 
> This is necessary as MySQL on the one hand and HSQLDB / Oracle on the other behave differently...
> If you want to search for '_abc' in MySQL, you have to use:
>     value like '\\_abc'
> In Oracle or HsqlDB, you have to use:
>    value like '\_abc'
> If you want to switch to another escape sequence like '|' , you can set it in HQL with value like '|_abc' escape '|'. Unfortunately, there is no way of setting it for Criteria queries, which would force me to rewrite all my Criteria queries in HQL. It would really be nice if the feature/improvement would be added...
