> 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.
