Part 4 Hibernate Query Language, Using HQL Select Query

Let us see the program on HQL select command,  which is going to cover complete object, partial object (More than one column), partial object (Single column)

here are the required files….

  • (POJO class)
  • Product.hbm.xml  (Xml mapping file )
  • hibernate.cfg.xml  (Xml configuration file)
  • (java file to write our hibernate logic)




Notes regarding

  • CASE 1:  For selecting complete objects (all rows from the table), see from line number 18 – 40 [ just remove the comments ] and check the out put
  • CASE 2:  For selecting partial objects, i mean more than one object, see from line number 42 – 63 [ just remove the comments ] and check the out put
  • CASE 3:  For selecting partial objects,  (selecting single row), see from line number 65 – 82 [ just remove the comments ] and check the out put
  • See the following output just am giving for CASE 3, and remember in case1 i typecast into POJO class type, in case 2 typecast into objects array, in case 3 typecast into that value type__ (in the while loop..)

  12. Nilesh says:

    in Notes regarding
    CASE 3: For selecting partial objects, (selecting single row),
    is not write. It should be “(selecting single column)” on the place of (“selecting single row”).

  13. Raghavender says:

    Hi excelent information about hibernet, I have one doubt here in the above example In partial object more than one column, we are getting values from object array based on index but these index values are coming from table column or HQL query.
    for more simeple understand:
    select, from Product p

    but in my Product table columns are id next name
    in this case if i call o[0] and o[1] it prints id and name or name and id ?
