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, 8.10 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 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.
