Subject [jira] [Commented] (DRILL-3218) Window function usage throws CompileException
Date Wed, 03 Jun 2015 01:35:50 GMT

    [ https://issues.apache.org/jira/browse/DRILL-3218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14570109#comment-14570109

Khurram Faraaz commented on DRILL-3218:
---------------------------------------


The below query fails after columns from CSV file are casted to appropriate datatypes. Casting
columns[0] to BIGINT also results in same Exception.

{code}
0: jdbc:drill:schema=dfs.tmp> SELECT MAX(cast( columns[2] as CHAR(2) )) OVER(PARTITION
BY cast( columns[2] as CHAR(2)) ORDER BY cast( columns[0] as INT )) FROM `allData.csv`;
Error: SYSTEM ERROR: org.codehaus.commons.compiler.CompileException: Line 243, Column 31:
Unknown variable or type "incoming"

Fragment 0:0

[Error Id: 46302e43-59e0-42b2-838a-32d1b239c486 on centos-01.qa.lab:31010] (state=,code=0)
{code}

Running just the aggregate gives correct results as shown below, the CompileException is seen
only when there is a window definition (with or without casting of the partition by and order
by keys)

{code}
0: jdbc:drill:schema=dfs.tmp> SELECT MAX(cast( columns[2] as CHAR(2) )) FROM `allData.csv`;
