[jira] [Commented] (HIVE-22892) Unable to compile query if CTE
joined
[ https://issues.apache.org/jira/browse/HIVE-22892?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17037268#comment-17037268 ]
Vineet Garg commented on HIVE-22892:
------------------------------------
[~kkasa] The patch doesn't seem right. With the current patch {{getUnescapedUnqualifiedTableName}} from {{genJoinLogicalPlan}} returns {{TOK_INSERT}} string instead of actual table name. The test works because table name is ignored
{code}
leftTableAlias = left.getChildCount() == 1 ? tableName :
unescapeIdentifier(left.getChild(left.getChildCount() - 1).getText().toLowerCase());
{code}
{{getUnescapedUnqualifiedTableName}} expects ast node of type {{TOK_TABNAME}} but in this case {{TOK_QUERY}} is being passed.
I think we can safely ignore calling {{getUnescapedUnqualifiedTableName}} if {{left.getChildCount}} is not 1 (since the table name it return is being ignored in that case). We should probably also put ASSERT in {{getUnescapedUnqualifiedTableName}} that ast node is always of type {{TOK_TABNAME}}
