> select count(1) from accounts a, transactions t where year(a.dt) = year(t.dt) and account_id = 22;
> $hdt$_0:$hdt$_1:a
> TableScan (TS_2)
> alias: a
> filterExpr: (((account_id = 22) and year(dt) is not null) and (year(dt)) IN (RS[6])) (type: boolean)
> {code}
> Ends up being evaluated as {{year(cast(dt as int))}} because the pruner only checks for final type, not the column type.

> .getPrimitiveTypeInfo(si.fieldInspector.getTypeName()));
