kate created CALCITE-6476:
-----------------------------
Summary: OracleDialect does not support CASE WHEN returning boolean
Key: CALCITE-6476
URL: https://issues.apache.org/jira/browse/CALCITE-6476
Project: Calcite
Issue Type: Wish
Components: core
Reporter: kate
Our requirement is to use Calcite to translate queries into different dialects.
During validation in the TPC-DS scenario, we found that {{Oracle}} does not
support SQL statements like
{{}}
{code:java}
SELECT * FROM xxx
WHERE CASE WHEN a > 10 THEN b < 5 ELSE c > 0 END;{code}
{{}}
Therefore, we hope to remove such predicates at the dialect like Oracle.
