Cassandra: cannot compare timestamp field in where clause
----------------------------------------------------------
Key: TEIID-3058
URL:
https://issues.jboss.org/browse/TEIID-3058
Project: Teiid
Issue Type: Bug
Components: Misc. Connectors
Affects Versions: 8.7
Environment: Cassandra with Teiid 8.7
Reporter: Ivan Chan
Assignee: Steven Hawkins
Fix For: 8.7.1, 8.9
It seems like Teiid is having problem to compare translate CQL if there is timestamp
comparison in where clause:
ORIGINAL SQL:
select "cassandrads_sales"."product_family" as
"cassandrads_sales_product_family",
"cassandrads_sales"."product_family" as
"cassandrads_sales_product_family1"
from "cassandrads"."sales" "cassandrads_sales"
where "cassandrads_sales"."the_date" <= '2013-05-01
00:00:00'
limit 1000
TRANSLATED CQL:
SELECT cassandrads.sales.product_family FROM cassandrads.sales WHERE
cassandrads.sales.the_date <= {ts'2013-05-01 00:00:00.0'} LIMIT 1000
And I got this error:
Caused by: org.teiid.translator.TranslatorException: line 1:55 no viable alternative at

If it is not possible to do time/ data comparison for CQL, maybe you guys should consider
to do it in memory instead. Thanks.
