--------------------------------------
Summary: Include SQL query text in the Origin of TreeNode
Key: SPARK-38616
URL: https://issues.apache.org/jira/browse/SPARK-38616
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.3.0
Reporter: Gengliang Wang
Assignee: Gengliang Wang
Spark SQL uses the class Origin for tracking the position of each TreeNode in
the SQL query text. When there is a parser error, we can show the position info
in the error message:
{code:java}
> sql("create tabe foo(i int)")
org.apache.spark.sql.catalyst.parser.ParseException:
no viable alternative at input 'create tabe'(line 1, pos 7)
== SQL ==
create tabe foo(i int)
-------^^^ {code}
It contains two fields: line and startPosition. This is enough for the parser
since the SQL query text is known.
However, the SQL query text is unknown in the execution phase. One solution is
to include the query text in Origin and show it in the runtime error message.
