-------------------------------------
Summary: Update error message to include all unsupported functions
when frame clause is used
Key: DRILL-4432
URL: https://issues.apache.org/jira/browse/DRILL-4432
Project: Apache Drill
Issue Type: Bug
Components: SQL Parser
Affects Versions: 1.6.0
Reporter: Khurram Faraaz
Priority: Minor
We need to update the error message to include LEAD, LAG, NTILE, and ranking
functions, right now we only say ROW/RANGE is not allowed with RANK, DENSE_RANK
or ROW_NUMBER functions, when frame clause is used in the window definition of
any of these window functions.
Another typo that needs fix in error message, it is not ROW/RANGE, it should be
ROWS/RANGE (rows not row)
An example of current error message that we see.
{noformat}
0: jdbc:drill:schema=dfs.tmp> select LEAD(columns[3]) OVER(PARTITION BY
CAST(columns[0] as integer) ORDER BY cast(columns[0] as integer) ROWS UNBOUNDED
PRECEDING) from dfs.tmp.`t_alltype.csv`;
Error: VALIDATION ERROR: From line 1, column 108 to line 1, column 111:
ROW/RANGE not allowed with RANK, DENSE_RANK or ROW_NUMBER functions
