Bryan Pendleton resolved DERBY-84.
----------------------------------
Resolution: Won't Fix
For the time being, we intend to preserve Derby's current behavior,
as we believe it to be standards-compliant, and adhering to the
SQL standard seems important for this case.
> Column aliasing could simplify queries
> --------------------------------------

> Key: DERBY-84
> URL: https://issues.apache.org/jira/browse/DERBY-84
> Project: Derby
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 10.0.2.0
> Reporter: Bob Gibson
> Assignee: Bryan Pendleton
> Priority: Minor
> Attachments: simpleTest.diff
>
>
> 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.
