--------------------------------
Summary: make window function using order by optional
Key: SPARK-31512
URL: https://issues.apache.org/jira/browse/SPARK-31512
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.5
Environment: spark2.4.5
hadoop2.7.7
Reporter: philipse
Hi all
In other sql dialect ,order by is not the must when using window function,we
may make it pararmteterized
the below is the case :
*select row_number()over() from test1*
Error: org.apache.spark.sql.AnalysisException: Window function row_number()
requires window to be ordered, please add ORDER BY clause. For example SELECT
row_number()(value_expr) OVER (PARTITION BY window_partition ORDER BY
window_ordering) from table; (state=,code=0)
So. i suggest make it as a choice,or we will meet the error when migrate sql
from other dialect，such as hive
