Row function cannot have column reference through table alias

马阳阳
We have a sql that compose a row with a table’s columns. The simplified sql is like:
INSERT INTO flink_log_sink
SELECT
b.id,
    Row(b.app_id, b.message)
FROM flink_log_source a
join flink_log_side b
on a.id = b.id;


When we submit the sql to Flink, the sql cannot be parsed, with the following error message:
org.apache.flink.table.api.SqlParserException: SQL parse failed. Encountered "." at line 11, column 8.
Was expecting one of:
")" ...
"," ...

Is this a bug or the expected behavior? If this is the expected behavior, what can we do to avoid it?


PS:
I tried to create a view to represent the join result,  and inserted the view into the sink table. Unfortunately, it didn’t work neither.

Re:Row function cannot have column reference through table alias

The error message when using a view is as the following:
org.apache.flink.table.api.TableException: Cannot generate a valid execution plan for the given query:

FlinkLogicalSink(table=[default_catalog.default_database.flink_log_sink], fields=[id, EXPR$1])
+- FlinkLogicalCalc(select=[id, ROW(family.app_id, family.message) AS EXPR$1])
+- FlinkLogicalJoin(condition=[true], joinType=[inner])
:- FlinkLogicalCalc(select=[app_id], where=[IS NOT NULL(id)])
: +- FlinkLogicalTableSourceScan(table=[[default_catalog, default_database, flink_log_source]], fields=[app_id, id, log_time, message])
+- FlinkLogicalTableSourceScan(table=[[default_catalog, default_database, flink_log_side]], fields=[id, family])

This exception indicates that the query uses an unsupported SQL feature.
Please check the documentation for the set of currently supported SQL features.

Is this a bug or the expected behavior? If this is the expected behavior, what can we do to avoid it?


PS:
I tried to create a view to represent the join result,  and inserted the view into the sink table. Unfortunately, it didn’t work neither.

Re: Row function cannot have column reference through table alias

使用ROW里面的 表别名.字段名 会出现解析错误，我之前使用hbase也有这个问题，我一般是在查询里面包一层子查询

Re: Row function cannot have column reference through table alias

已知问题，后续版本会修复，作为临时解决办法，可以使用直接这样去构造 (b.app_id, b.message)，不用添加 ROW 关键字。
