Zhenghua Gao commented on FLINK-13651: -------------------------------------- [~liyu] [~jark] The root cause is PlannerExpressionParserImpl in both old planner and blink planner use old type system, and we must keep them as the same for packaging concern, see https://issues.apache.org/jira/browse/FLINK-13267 The impact of using new type system for both PlannerExpressionParserImpl needs to evaluate. I prefer to postpone it to later release since this only affects Table API. [~lzljs3620320] Is there any plan to refactor the Scala style Expression parser? > Blink planner should parse char(n)/varchar(n)/decimal(p, s) inside a string > to corresponding datatype > ----------------------------------------------------------------------------------------------------- > > Key: FLINK-13651 > URL: https://issues.apache.org/jira/browse/FLINK-13651 > Project: Flink > Issue Type: Bug > Components: Table SQL / Planner > Affects Versions: 1.9.0, 1.10.0 > Reporter: Zhenghua Gao > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > could reproduce in ScalarFunctionsTest: > `testAllApis( > 'f31.cast(DataTypes.DECIMAL(38, 18)).truncate(2), > "f31.cast(DECIMAL(38, 18)).truncate(2)", > "truncate(cast(f31 as decimal(38, 18)), 2)", > "-0.12")` > > A possible reason is LookupCallResolver treat decimal(38, 18) as a function > call. -- This message was sent by Atlassian Jira (v8.3.4#803005)
