Aleksey Plekhanov updated CALCITE-5410:
---------------------------------------
Description:
Queries like:
{code:java}
SELECT 1.0 % 2 {code}
Fail on planning with:
{noformat}
java.lang.AssertionError: Conversion to relational algebra failed to preserve
datatypes:
validated type:
RecordType(INTEGER NOT NULL EXPR$0) NOT NULL
converted type:
RecordType(DECIMAL(2, 1) NOT NULL EXPR$0) NOT NULL
at
org.apache.calcite.sql2rel.SqlToRelConverter.checkConvertedType(SqlToRelConverter.java:494)
at
org.apache.calcite.sql2rel.SqlToRelConverter.convertQuery(SqlToRelConverter.java:609)
at
org.apache.calcite.prepare.Prepare.prepareSql(Prepare.java:257){noformat}
It happens because {{PERCENT_REMAINDER}} operator replaced with {{MOD}}
operator by {{StandardConvertletTable}} and these two operators have different
return-type inference settings. So, different types are inferenced at SQL
validation phase and SqlToRel converter phase.
