[jira] [Commented] (PHOENIX-4871) Query parser throws exception on
parameterized join
[ https://issues.apache.org/jira/browse/PHOENIX-4871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16875176#comment-16875176 ]
Lars Hofhansl commented on PHOENIX-4871:
----------------------------------------
Looks good.
I do wonder why the PQS would execute a query *any* different than a normal fat client, though!

> As a workaround you can change the order of tables. Meaning that the table that has the condition in the where clause must appear first in the query. For the example above this will work
> {code:java}
> SELECT "A"."a2" FROM "B" JOIN "A" ON ("A"."a1" = "B"."b1" ) WHERE "B"."b2" = ? {code}
> After debugging this it looks like the Phoenix server splits the join in two separated queries and constructs two java.sql.Statement. The first of the two is referenced for reading the query metadata down steam and since the column in the condition in the example above is in table `B` rather than `A` it won't exists in the first query and later it fails with the error above.
> That's why changing the order of tables in the query fixes the issue.
