> Key: IGNITE-16077
> URL: https://issues.apache.org/jira/browse/IGNITE-16077
> Project: Ignite
> Issue Type: Bug
> Reporter: Aleksey Plekhanov
> Priority: Major
> Labels: calcite2-required, calcite3-required
>
> For example:
> {noformat}
> create table t(d date)
> create index my_index on t(d);
> insert into t values (date '2021-01-01')
> insert into t values (date '2021-01-02')
> select * from t where d = date '2021-01-01'
> {noformat}
> Fails with:
> {noformat}
> Caused by: class org.apache.ignite.internal.processors.query.IgniteSQLException: Failed to wrap object into H2 Value. java.lang.Integer cannot be cast to java.sql.Date
> at org.apache.ignite.internal.processors.query.h2.index.keys.H2ValueWrapperMixin.wrapToValue(H2ValueWrapperMixin.java:37)
> at org.apache.ignite.internal.processors.query.h2.index.keys.DateIndexKey.<init>(DateIndexKey.java:31)

> {noformat}
> We should convert DATE/TIME/TIMESTAMP from internal presentation (see {{TypeUtils.fromInternal()}}) before creating {{IndexRow}}.
