Guillaume commented on HIVE-21144:
----------------------------------
I'm pretty sure that you are right. And there is no way to report a bug to
Simba or Hortonworks if I am not a paying customer, so I'm pretty much out of
luck. Thanks!
> ODBC with prepared statement fail inside a CTE
> ----------------------------------------------
>
> Key: HIVE-21144
> URL: https://issues.apache.org/jira/browse/HIVE-21144
> Project: Hive
> Issue Type: Bug
> Components: ODBC
> Affects Versions: 3.1.0
> Reporter: Guillaume
> Priority: Major
>
> I am trying to execute a very simple query, using python/pyodbc on Windows
> (with a working system-wide odbc DSN: HiveProd):
> {code:java}
> import pyodbc cnxn = pyodbc.connect('DSN=HiveProd', autocommit=True)
> cursor = cnxn.cursor()
> # works
> q="select ? as lic, ? as cpg"
> # fails
> q="with init as (select ? as lic, ? as cpg) select * from init"
> cursor.execute(q, '1', 'some string')
> for row in cursor:
> print(row.lic, row.cpg)
> {code}
> Basically, create an odbc connection, run a query with a prepared statement
> and print the result.
> A basic query works fine. If I put this query inside a CTE, I get:
> {{ cursor.execute("with init as (select ? as lic, ? as cpg) select * from
> init", '1', 'some string') pyodbc.ProgrammingError: ('42000', "[42000]
> [Hortonworks][Hardy] (80) Syntax or semantic analysis error thrown in server
> while executing query. Error message from server: Error while compiling
> statement: FAILED: ParseException line 1:21 can not recognize input near '?'
> 'as' 'lic' in select clause (80) (SQLPrepare)")}}
> This is not specific to python as I get the same issue with .Net.
> Trying the same with JDBC works fine.
> Testing on Hive 3.1.0 from Hdp 3.1.0
