Xingcan Cui updated FLINK-10049: -------------------------------- Summary: Correctly handle NULL arguments in SQL built-in functions (was: Unify the processing logic for NULL arguments in SQL built-in functions) > Correctly handle NULL arguments in SQL built-in functions > --------------------------------------------------------- > > Key: FLINK-10049 > URL: https://issues.apache.org/jira/browse/FLINK-10049 > Project: Flink > Issue Type: Improvement > Components: Table SQL / API > Reporter: Xingcan Cui > Assignee: vinoyang > Priority: Major > > Currently, the built-in functions treat NULL arguments in different ways. > E.g., ABS(NULL) returns NULL, while LOG10(NULL) throws an NPE. The general > SQL-way of handling NULL values should be that if one argument is NULL the > result is NULL. We should unify the processing logic for that. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
