> 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 input '2013-05-01 00:00:0
> at org.teiid.translator.cassandra.CassandraQueryExecution.execute(CassandraQueryExecution.java:80)
> at org.teiid.translator.cassandra.CassandraQueryExecution.execute(CassandraQueryExecution.java:72)
> at org.teiid.dqp.internal.datamgr.ConnectorWorkItem.execute(ConnectorWorkItem.java:325)
> at org.teiid.dqp.internal.process.DataTierTupleSource.getResults(DataTierTupleSource.java:298)
> at org.teiid.dqp.internal.process.DataTierTupleSource.nextTuple(DataTierTupleSource.java:135)
> If it is not possible to do time/ data comparison for CQL, maybe you guys should consider to do it in memory instead. Thanks.
