             Summary: Couchbase - query with comparison criteria not properly translated
                 Key: TEIID-4972
                 URL: https://issues.jboss.org/browse/TEIID-4972
             Project: Teiid
          Issue Type: Bug
          Components: Misc. Connectors
    Affects Versions: 8.12.x-6.4
            Reporter: Juraj Duráni
            Assignee: Steven Hawkins
            Priority: Blocker


Issuing simple query with comparison criteria like \[1\] returns empty result. From what I can see, the query is not properly translated - it is translated to query with syntax error \[2\].

Another issue here which I can see is that Teiid does not provide any information to the user that query actually failed. Only empty result is returned. This one, I will report it as a separate issue.

{code:sql|title=\[1\] Query}
SELECT BQT1.SmallA.FloatNum FROM BQT1.SmallA WHERE BQT1.SmallA.FloatNum = 7
{code}

{code:plain|title=\[2\] Source-specific query}
10:16:09,749 DEBUG [org.teiid.CONNECTOR] (Worker12_QueryProcessorQueue86) TEIID29001 Source-specific Query: SELECT TONUMBER(`$cb_c1_FloatNum`) FROM `dvqe_small` `$cb_t1` LET `$cb_c1_FloatNum` = `$cb_t1`.`FloatNum`TONUMBER() WHERE TONUMBER(`$cb_c1_FloatNum`) = 7.0 AND `$cb_t1`.`type` = 'SmallA'
{code}
