Apache Spark commented on SPARK-34199: -------------------------------------- User 'linhongliu-db' has created a pull request for this issue: https://github.com/apache/spark/pull/31286 > Block `count(table.*)` to follow ANSI standard and other SQL engines > -------------------------------------------------------------------- > > Key: SPARK-34199 > URL: https://issues.apache.org/jira/browse/SPARK-34199 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.2.0 > Reporter: Linhong Liu > Priority: Major > > In spark, the count(table.*) may cause very weird result, for example: > select count(*) from (select 1 as a, null as b) t; > output: 1 > select count(t.*) from (select 1 as a, null as b) t; > output: 0 > > After checking the ANSI standard, count(*) is always treated as count(1) > while count(t.*) is not allowed. What's more, this is also not allowed by > common databases, e.g. MySQL, oracle. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
