--------------------------------
Summary: SQL UserDefineTableFunction does not take CompositeType
input correctly
Key: FLINK-7678
URL: https://issues.apache.org/jira/browse/FLINK-7678
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 1.3.2
Reporter: Rong Rong
UDF is using FlinkTypeFactory to infer operand type while UDTF does not go
through the same code path. This result in:
{code:console}
org.apache.flink.table.api.ValidationException: SQL validation failed. From
line 1, column 38 to line 1, column 44: No match found for function signature
func(<COMPOSITE(Row(f0: Integer, f1: String))>)
Caused by: org.apache.calcite.runtime.CalciteContextException: From line 1,
column 38 to line 1, column 44: No match found for function signature
func(<COMPOSITE(Row(f0: Integer, f1: String))>)
{code}
