Serge Rielau created SPARK-47907: ------------------------------------ Summary: Put removal of '!' as a synonym for 'NOT' on a keyword level under a config Key: SPARK-47907 URL: https://issues.apache.org/jira/browse/SPARK-47907 Project: Spark Issue Type: Bug Components: Spark Core Affects Versions: 4.0.0 Reporter: Serge Rielau
Recently we dissolved the lexer equivalence between '!' and 'NOT'. ! is a prefix operator and a synonym for NOT only in that case. But NOT is used in many more cases in the grammar. Given that there are a handful of known scenearios where users have exploited the undocumented loophole it's best to add a config. Usage found so far is: `c1 ! IN(1, 2)` `c1 ! BETWEEN 1 AND 2` `c1 ! LIKE 'a%'` But there are worse cases: c1 IS ! NULL CREATE TABLE T(c1 INT ! NULL) or even CREATE TABLE IF ! EXISTS T(c1 INT) -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
