Hi All,

 

I ran into a problem with subqueries and filters, where the order of the parameters (positional and filter parameters, not named parameters) got messed up. I searched through the forum and JIRA and found to similar issues:

 

1)      NH-1098 (I'm not sure, if it's exactly the same problem, but pretty much sounds like it)

2)      http://forum.hibernate.org/viewtopic.php?t=971270

 

After some debugging I think I found the problem in method ProcessFilters in  QueryParameters (line 369 ff.). There, the SQL parts of the statement are analyzed and the parameters are added to the SQL string. During the loop the parameters (positional and filter) are added in the order they occur in the parts list, but only the filter parameters are added to the parameter list. After processing the parts, the positional parameters are added at the end of the parameter list, which may result in a wrong order.

 

I worked out a fix for the problem, but I'm not sure, if it does not cause other problems and would appreciate it if somebody could have a look on it. I can provide the fix and a test case. Should I open a new JIRA issue or should I upload the information to NH-1098 ?

 

Best Regards,

Wolfgang
