PlannerExpressionParserImpl of Blink planner does not support char( n
)/varchar( n )/decimal(p, s)/timestamp(p) patterns.
> Blink planner should parse char(n)/varchar(n)/decimal(p, s) inside a string

> 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
>
> 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.
