----------------------------------
Summary: All kinds of problem when conversion from Logical type to
DataType
Key: FLINK-13604
URL: https://issues.apache.org/jira/browse/FLINK-13604
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Affects Versions: 1.9.0
Reporter: Danny Chan
Fix For: 1.10.0
For Blink Planner:
# Time(3) is converted to Time, the precision is lost
# ROW<`f0` INT NOT NULL, `f1` BOOLEAN> is converted to ROW<`f0` INT, `f1`
BOOLEAN>, the nullable attr is lost
the conversion code is:
{code:java}
LogicalTypeDataTypeConverter.fromLogicalTypeToDataType(FlinkTypeFactory.toLogicalType(relType));
{code}
For Flink planner:
# All the Char type is converted to String type, which is totally wrong.
# All the decimal type is converted to Legacy(BigDecimal) which is confusing ..
The conversion code is:
{code:java}
TypeConversions.fromLegacyInfoToDataType(FlinkTypeFactory.toTypeInfo(relType))
{code}
Please see the tests
SqlToOperationConverterTest#testCreateTableWithFullDataTypes.
