--------------------------------------
Assignee: Apache Spark
> SQL Error Attribution Framework
> -------------------------------
>
> Key: SPARK-38615
> URL: https://issues.apache.org/jira/browse/SPARK-38615
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Gengliang Wang
> Assignee: Apache Spark
> Priority: Major
> Attachments: SQL Error Attribution Framework.pdf

>
> Currently, there is not enough error context for runtime ANSI failures.
> In the following example, the error message only tells that there is a
> "divide by zero" error, without pointing out where the exact SQL statement is.

> I suggest that we provide details in the error message, including:
> * the problematic expression from the original SQL query, e.g.
> "ss3.store_sales / ss2.store_sales store_q2_q3_increase"
> * the line number and starting char position of the problematic expression,
> in case of queries like "select a + b from t1 union select a + b from t2"
> So that the error message will be precise
> {code:java}
> org.apache.spark.SparkArithmeticException: divide by zero
> SparkArithmeticException: divide by zero. To return NULL instead, use
> 'try_divide'. If necessary set spark.sql.ansi.enabled to false (except for
> ANSI interval type) to bypass this error.
