Re-hi, I actually realized that the problem comes from the fact that the datastream that I am registering does not create properly the types.
I am using something like DataStream<Tuple> ... .returns("TupleX<,....,java.sql.Timestamp, java.sql.Time>")...and I was expecting that these will be converted to SqlTimeTypeInfo...but it is converted to GenericType. Anythoughts how I could force the type to be recognize as a SqlTimeType? From: Radu Tudoran Sent: Tuesday, October 25, 2016 4:46 PM To: 'user@flink.apache.org' Subject: TIMESTAMP TypeInformation Hi, I would like to create a TIMESTAMP type from the data schema. I would need this to match against the FlinkTypeFactory (toTypeInfo()) def toTypeInfo(relDataType: RelDataType): TypeInformation[_] = relDataType.getSqlTypeName match { case BOOLEAN => BOOLEAN_TYPE_INFO case TINYINT => BYTE_TYPE_INFO case SMALLINT => SHORT_TYPE_INFO case INTEGER => INT_TYPE_INFO case BIGINT => LONG_TYPE_INFO case FLOAT => FLOAT_TYPE_INFO case DOUBLE => DOUBLE_TYPE_INFO case VARCHAR | CHAR => STRING_TYPE_INFO case DECIMAL => BIG_DEC_TYPE_INFO // date/time types case DATE => SqlTimeTypeInfo.DATE case TIME => SqlTimeTypeInfo.TIME case TIMESTAMP => SqlTimeTypeInfo.TIMESTAMP I tried to use create the TypeInformation by calling directly SqlTimeTypeInfo.TIMESTAMP . However, it seems that relDataType.getSqlTypeName match is of type ANY instead of being of type TIMESTAMP. Any thoughts of how to create the proper TIMESTAMP typeinformation?
