-----------------------------------
Summary: Add possibility to get column names
Key: FLINK-4686
URL: https://issues.apache.org/jira/browse/FLINK-4686
Project: Flink
Issue Type: New Feature
Components: Table API & SQL
Reporter: Timo Walther
For debugging and maybe for visualization in future (e.g. in a shell) it would
be good to have the possibilty to get the names of {{Table}} columns. At the
moment the user has no idea how the table columns are named; if they need to be
matched with POJO fields for example.
My suggestion:
{code}
Schema s = table.schema();
TypeInformation<?> type = s.getType(1);
TypeInformation<?> type = s.getType("col");
String s = s.getColumnName(1);
String[] s = s.getColumnNames();
{code}
