Subject [jira] Commented: (DERBY-84) Column aliasing could simplify queries
Date Fri, 03 Jun 2005 04:12:13 GMT
     [ http://issues.apache.org/jira/browse/DERBY-84?page=comments#action_66956 ]
     
Shreyas Kaushik commented on DERBY-84:
--------------------------------------

So, can this be closed ? Should the hibernate group be informed about the way they generate
queries to take care of this ?
BTW have a look at this link, http://www.hibernate.org/80.392.html

> Currently, one can not use an alias to simplify queries.  For example, being able to
alias "LongDescriptiveColumnName" AS LDCN would allow one to use the alias elsewhere in the
query, e.g., the WHERE clause:
> SELECT LongDescriptiveColumnName AS LDCN FROM MyTable WHERE LDCN LIKE '%testing%';
> The current result is a message like:
> ERROR 42X04: Column 'LDCN' is not in any table in the FROM list or it appears within
a join specification and is outside the scope of the join specification or it appears in a
HAVING clause and is not in the GROUP BY list.  If this is a CREATE or ALTER TABLE statement
then 'LDCN' is not a column in the target table.
