[jira] [Commented] (DERBY-39) Strange error in JOIN ON clause
[ https://issues.apache.org/jira/browse/DERBY-39?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13764230#comment-13764230 ]
Knut Anders Hatlen commented on DERBY-39:
-----------------------------------------
The scope of a <table factor> is defined in SQL:2003, part 2, section 7.6 <table reference>, syntax rule 5. My understanding of that rule is that A (in the minimal repro posted on 18/Feb/11) is not in scope in the <join condition> because A is not contained in the corresponding <joined table>, so the query is not standard SQL. I'll close the bug report as Won't Fix.

> The exception:
> ---------------------------------------
> Error: An ON clause associated with a JOIN operator is not valid.
> ---------------------------------------
> happens when I run the below SQL script:
> ---------------------------------------
> SELECT
> THIS.DOSSIERTEMPLATE_ID
> FROM DOSSIERTEMPLATE THIS,
> ENTITLEMENT UNBOUND_ENTITLE
> INNER JOIN
> ENTITLEMENT II
> ON UNBOUND_ENTITLE.ENTITLEMENT_ID = II.ENTITLEMENT_ID
> INNER JOIN
> DOSSIERTEMPLATERESOURCE BB
> ON II.ENTITLED_TO_RESOURCE_ID_OID = BB.DOSSIERTEMPLATERESOURCE_ID
> INNER JOIN
> I18N THIS_LABEL
> ON THIS.LABEL_I18N_ID_OID = THIS_LABEL.I18N_ID
> ---------------------------------------
> It works fine if I run without the LABEL join
> ---------------------------------------
> SELECT
> THIS.DOSSIERTEMPLATE_ID
> FROM DOSSIERTEMPLATE THIS,
> ENTITLEMENT UNBOUND_ENTITLE
> INNER JOIN
> ENTITLEMENT II
> ON UNBOUND_ENTITLE.ENTITLEMENT_ID = II.ENTITLEMENT_ID
> INNER JOIN
> DOSSIERTEMPLATERESOURCE BB
> ON II.ENTITLED_TO_RESOURCE_ID_OID = BB.DOSSIERTEMPLATERESOURCE_ID
> ---------------------------------------
> The column LABEL_I18N_ID_OID is BIGINT and has a FK to I18N_ID, which is BIGINT as well
