Subject [jira] Commented: (TORQUE-113) doDelete with invalid column should throw exception, not delete all rows
Date Sat, 19 Apr 2008 11:02:22 GMT

    [ https://issues.apache.org/jira/browse/TORQUE-113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12590694#action_12590694

Thomas Fischer commented on TORQUE-113:
---------------------------------------

I do not see a good reason for normalizing column names. Taking the exact case from the schema
is what one would expect; it offers full flexibility; and it provides consistent case handling
over column names, table names and database names.

>             Project: Torque
>          Issue Type: Bug
>          Components: Runtime
>    Affects Versions: 3.3
>            Reporter: Julian Zinn
>             Fix For: 3.3, 4.0

> The following (incorrect) client code should cause an exception to be thrown.  Instead
of an exception, all rows in table T1 are deleted.
> {code}
> T1Peer.doDelete(new Criteria().add(T2Peer.COL, 2));
> {code}
> This code appeared in a project I am working on.  The intent was to delete rows from
table T2.
> Before the fix for TORQUE-93, this code had the intended effect becaue {{T1Peer.doDelete(criteria)}}
just passed the criteria object to {{BasePeer.doDelete(criteria)}}.  Since the only reference
BasePeer had to a table was table T2 in the criteria, only rows in table T2 were deleted.
> Now that {{T1Peer.doDelete(criteria)}} calls {{BasePeer.doDelete(criteria, TABLE_NAME)}}
instead, the test {{if (crit.containsKey(key))}} in {{BasePeer.processTables()}} always fails.
 This leads to an empty where clause, causing all rows in table T1 to be deleted.
> *Expect*: All Criterion objects in a Criteria should be used in the final where clause.
 If not, an exception should be thrown.
