JPQL can not support asterisk (*) in COUNT function #66

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
"The COUNT function takes either an identification variable or a path 
expression as its argument. This path expression can resolve to a state field 
or a single-valued association field", which is stated in JPQL.

The query "select count(*) from employee e" can not work. It could be resolved 
by replacing * with alias name, as below:

"select count(e) from employee e"

The method "_count(Class<?> type)" in BaseDAO, and method 
"generateRowCountQL()" in BaseSearchProcessor should be changed.
