--------------------------------

             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}
