Subject [jira] Commented: (TORQUE-89) OrderByColumn for COUNT, SUM
Date Sun, 15 Apr 2007 13:02:15 GMT

Thomas Fischer commented on TORQUE-89:
--------------------------------------

I have realized that, but maybe I have been unclear in my answer. I'll try again.
The change you propose to removeSQLFunction() violates the contract of removeSQLFunction(),
namely to remove the sql function whenever possible. And I see no simple way to comply with
the contract if no dot or star is present.

>                 Key: TORQUE-89
>                 URL: https://issues.apache.org/jira/browse/TORQUE-89
>             Project: Torque
>          Issue Type: Bug
>          Components: Runtime
>    Affects Versions: 3.3-RC2
>         Environment: Linux
>            Reporter: Stefan Birrer

> I've a "complicated" JOIN statement that features some custom column like "COUNT(a) AS
ca".
> Torque runtime fails on the 
> Criteria::addAscendingOrderByColumn("ca")
> because it expects a full qualified table.columnName which is not the case for the example
"ca" column.
> The problem can be fixed by adapting the following functions (3.3-RC2):
> src/java/org/apache/torque/util/SQLBuilder.java
> removeSQLFunction(final String name) : name must not necessarily contain '.' or '*" thus
replacing the first thrown exception with a "return name" fixes that issue
> processOrderBy(...) : in the for loop, strippedColumnName must not contain '.'  hence
replacing the first thrown exception with "orderByColumn.add(orderByColumn); break;" fixes
the issue
> This are quick fixes and I guess you want to reconsider whether you want to implement
it that way. After these two changes, it was working correctly though.
