What changes were proposed in this pull request?
This PR will address the issue SPARK-54634.
With this, I am adding a user-friendly error message when users write SQL queries with an empty IN clause, like: SELECT * FROM table WHERE col IN ()
Why are the changes needed?
When users write SQL with an empty IN clause, Spark currently produces a syntax error of subclass [PARSE_SYNTAX_ERROR], which leads the user to believe that their syntax is incorrect, whereas the actual issue is due to the absence of values for the IN clause. Hence, the current error message does not communicate the right intention to the user.
This change provides a clear, actionable error message that explains the actual problem
and suggests alternatives.
