------------------------------------
Summary: SPARK-42045 is incomplete in supporting ANSI_MODE fro
round() and bround()
Key: SPARK-42546
URL: https://issues.apache.org/jira/browse/SPARK-42546
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.3.2, 3.4.0
Reporter: Serge Rielau
under ANSI mode SPARK-42045 added error conditions insetad of silent overflows
for edge cases in round() and bround().
However it appears this fix works only for the INT data type. Trying it on a
e.g. SMALLINT the function still returns wrong results:
{code:java}
spark-sql> select round(2147483647, -1);
[ARITHMETIC_OVERFLOW] Overflow. If necessary set "spark.sql.ansi.enabled" to
"false" to bypass this error.{code}
{code:java}
spark-sql> select round(127y, -1);
-126 {code}
