Cheng Lian created SPARK-12725: ---------------------------------- Summary: SQL generation suffers from name conficts introduced by some analysis rules Key: SPARK-12725 URL: https://issues.apache.org/jira/browse/SPARK-12725 Project: Spark Issue Type: Sub-task Reporter: Cheng Lian
Some analysis rules generate auxiliary attribute references with the same name but different expression IDs. For example, {{ResolveAggregateFunctions}} introduces {{havingCondition}} and {{aggOrder}}, and {{DistinctAggregationRewriter}} introduces {{gid}}. This is OK for normal query execution since these attribute references get expression IDs. However, it's troublesome when converting resolved query plans back to SQL query strings since expression IDs are erased. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
