Max Rydahl Andersen commented on HHH-2077:
------------------------------------------

I assume it was done like because the author were not sure if he would like that constructor to be public api.

>                 Key: HHH-2077
>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2077
>             Project: Hibernate3
>          Issue Type: Improvement
>          Components: query-criteria
>    Affects 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 Estimate: 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...
