--------------------------------------
Summary: Fix incorrect error positions for invalid data types in
CREATE FUNCTION
Key: SPARK-55907
URL: https://issues.apache.org/jira/browse/SPARK-55907
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 4.2.0
Reporter: Gengliang Wang
Assignee: Gengliang Wang
In CREATE FUNCTION statements, data type errors (e.g. STRUCT without <>) in
parameters or return types were reported with incorrect line/position
information. This happened because data types were not validated during the
initial AST visit of visitCreateUserDefinedFunction—instead, parameter and
return type text was captured as raw strings via source() and only parsed later
in a separate context, losing the original position information.
