ScalarOperatorGens::generateCast
[ https://issues.apache.org/jira/browse/FLINK-15546?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rui Li updated FLINK-15546:
---------------------------
Summary: Obscure error message from ScalarOperatorGens::generateCast (was: Obscure error message in ScalarOperatorGens::generateCast)
> Obscure error message from ScalarOperatorGens::generateCast
> -----------------------------------------------------------
>
> Key: FLINK-15546
> URL: https://issues.apache.org/jira/browse/FLINK-15546
> Project: Flink
> Issue Type: Improvement
> Reporter: Rui Li
> Priority: Major
>
> Consider the following case:
> {noformat}
> Flink SQL> describe foo;
> root
> |-- x: ROW<`f1` DOUBLE, `f2` VARCHAR(10)>
> Flink SQL> insert into foo select row(1.1,'abc');
> [INFO] Submitting SQL update statement to the cluster...
> [ERROR] Could not execute SQL statement. Reason:
> org.apache.flink.table.planner.codegen.CodeGenException: Unsupported cast from 'ROW' to 'ROW'.
> {noformat}
> Users are unlikely to figure out what goes wrong from the above error message. Something like {{Unsupported cast from 'ROW<DECIMAL(2,1), CHAR(3)>' to 'ROW<DOUBLE, VARCHAR(10)>'}} will be more helpful.
