How can I use MySQL assign operator(:=) in hibernate native query?

I\'m using Hibernate. I wrote some native query because I need to use sub select statement.

Query looks like this:

SELECT sub.rownum FROM 
    (SELEC

you can implement this is a slightly different way.. you need to replace the : operator with something else (say '|' char ) and in your interceptor replace the '|' with the : .

this way hibernate will not try to think the : is a param but will ignore it

For the interceptor logic you can refer to the hibernate manual

This has worked for me using MySQL 5.

remember, this replacing of : must be only done to ':=' and other MySQL specific requirments.. don't try to replace the : for the param-placeholders. (hibernate will not be able to identify the params then)
