---------------------------------------------------------------------
        Key: HB-111
    Summary: Invalid sql alias computation for fields with formulas...
       Type: Bug

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0rc2

Description:
Trying to define a computed field (i.e. 'status1000' as the result of the following computation: status+1000; where 'status' is a table column) in this way:

<property column="STATUS+1000" length="10" name="status1000" not-null="true" type="java.lang.Long" update="false" insert="false"/>

if the first 7 chars of the attribute 'column' contains some non-valid chars for sql aliases, the produced SELECT statement will fail.

In the example the alias for the computed field is 'STATUS+16_', which is not a valid sql alias.

SELECT WkfPr0_.pkid as pkid, ..., WkfPr0_.STATUS+1000 as STATUS+16_ FROM WKF_PROCESS_CLASS WkfPr0_ WHERE WkfPr0_.pkid=?

if the field involved in the formula has a longer name i.e. MYSTATUS --> formula=MYSTATUS+1000, the computed alias is MYSTATU16_, which is a valid alias.
