[jira] [Updated] (IGNITE-17890) Calcite engine. Support index scan on boolean field
[ https://issues.apache.org/jira/browse/IGNITE-17890?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aleksey Plekhanov updated IGNITE-17890:
---------------------------------------
Description:
Currently, if table has index on boolean field it can't be used, since queries like
{code:java}
SELECT * FROM tbl WHERE a = TRUE
{code}
Simplified by Calcite to
{code:java}
SELECT * FROM tbl WHERE a {code}
Condition `{{{}a{}}}` is not supported for building search bounds (see \{{RexUtils.isSupportedTreeComparison()}}) and such an index can't be used.
