Siying Dong updated HIVE-1517:
------------------------------
Attachment: HIVE-1517.10.patch
I tried some simple way to make it work. It doesn't seem to be such a simple
task. Instead, I added this to block it:
<pre>
// TODO: add support to referencing views in foreign databases.
if (!tab.getDbName().equals(db.getCurrentDatabase())) {
throw new SemanticException(ErrorMsg.INVALID_TABLE_ALIAS.
getMsg("Referencing view from foreign databases is not
supported."));
}
I'll add the view support as a follow-up patch.
> ability to select across a database
