[teiid-issues] [JBoss JIRA] (TEIID-4633) Odata $expand over Oracle tables generates bad query

[Steven Hawkins (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-4633?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13336510#comment-13336510 ] 

Steven Hawkins commented on TEIID-4633:
---------------------------------------

The logic is trying to fetch the values as an array/row value, but oracle does not directly allow that in the select clause.  We'll need to refine the array type handling pushdown for oracle.

> Query generated to obtain referenced records ($expand many to one) is generated with parentheses, 
> Generated query for Oracle*:
> SELECT g_0."CATEGORY_ID", (g_0."CATEGORY_ID", g_0."NAME", g_0."LAST_UPDATE") FROM "SAKILA"."CATEGORY" g_0
> Generated query for MySQL is:
> SELECT g_0.category_id, g_0.name, g_0.last_update FROM Sakila.category AS g_0
> * Note the parentheses enclosing all columns but PK, this raises "ORA-00907: missing right parenthesis".
