MaxGekk opened a new pull request #31810: URL: https://github.com/apache/spark/pull/31810
### What changes were proposed in this pull request? In the PR, I propose to override the `typeName()` method in `YearMonthIntervalType` and `DayTimeIntervalType`, and assign them names according to the ANSI SQL standard: <img width="836" alt="Screenshot 2021-03-11 at 17 29 04" src="https://user-images.githubusercontent.com/1580697/110802854-a54aa980-828f-11eb-956d-dd4fbf14aa72.png";> but keep the type name as singular according existing naming convention for other types. ### Why are the changes needed? To improve Spark SQL user experience, and have readable types in error messages. ### Does this PR introduce _any_ user-facing change? Should not since the types has not been released yet. ### How was this patch tested? By running the modified tests: ``` $ build/sbt "test:testOnly *ExpressionTypeCheckingSuite" $ build/sbt "sql/testOnly *SQLQueryTestSuite -- -z windowFrameCoercion.sql" $ build/sbt "sql/testOnly *SQLQueryTestSuite -- -z literals.sql" ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
