KnightChess created HUDI-4799:
---------------------------------
Summary: improve analyzer exception tip when can not resolve
expression
Key: HUDI-4799
URL: https://issues.apache.org/jira/browse/HUDI-4799
Project: Apache Hudi
Issue Type: Improvement
Components: spark-sql
Reporter: KnightChess
sql:
merge into hudi_mor_pk_cbfield_tbl3 as target
using (select id, dt from delete_sync_test where concat_ws('1', '2') and id =
1) as source
on target.id = source.id
when matched then update set target.ts = source.dt
then Exception desc is doubtful
{code:shell}
Exception in thread "main" org.apache.spark.sql.AnalysisException: Cannot
resolve 'target.id,'source.id in (target.id = source.id), the input columns is:
['id, 'dt, _hoodie_commit_time#0, _hoodie_commit_seqno#1, _hoodie_record_key#2,
_hoodie_partition_path#3, _hoodie_file_name#4, id#5L, ts#6L, name#7]

after imporve:
it is easy find error
