Summary: Improve validation and semantic analysis in HPL/SQL
Key: HIVE-24315
URL: https://issues.apache.org/jira/browse/HIVE-24315
Project: Hive
Issue Type: Improvement
Components: hpl/sql
Reporter: Attila Magyar
Assignee: Attila Magyar
There are some known issues that need to be fixed. For example it seems that
arity of a function is not checked when calling it, and same is true for
parameter types. Calling an undefined function is evaluated to null and
sometimes it seems that incorrect syntax is silently ignored.
In cases like this a helpful error message would be expected, thought we should
also consider how PL/SQL works and maintain compatibility.
