HQL implicit join in where clause generate cross join instead of inner join

Question

I\'m using Hibernate 3.6 and MSSQL 2012.

When executing this HQL

select tbl.state from Property tbl where tbl.state = 1 and tbl.entity.state = 1 and
         


        

Answer 1

When using HQL, always use proper aliases when performing join operations.Your query should be something like that:

select tbl.state 
from Property tbl 
left join tbl.entity entity 
where tbl.state = 1 
    and entity.state = 1 
    and entity.className = 'com....' 
    and tbl.fieldName = 'fieldName'

Otherwise if you try to use tbl.entity.someProperty, in HQL, it will always create a crossJoin
