Patrick Szalapski commented on IMPALA-3149:
-------------------------------------------
I've simplified my query as much as possible. I get the "unexpected character"
error on this query over ODBC using Cloudera ODBC driver 2.05.41.1029 for
Windows.
{{with nextMatchId as (}}
{{ select min(match_id) as match_id}}
{{ from user}}
{{ where user_id = ?}}
{{) }}
{{select c.*}}
{{from candidate c}}
{{join nextMatchId on nextMatchId.match_id=c.match_id}}
??System.Data.Odbc.OdbcException??
?? HResult=0x80131937??
?? Message=ERROR [HY000] [Cloudera][ImpalaODBC] (110) Error while executing a
query in Impala: [HY000] : AnalysisException: Syntax error in line 5:??
?? where user_id = ???

??Encountered: Unexpected character??
??Expected: CASE, CAST, DEFAULT, EXISTS, FALSE, IF, INTERVAL, NOT, NULL,
REPLACE, TRUNCATE, TRUE, IDENTIFIER??
> Bind variable issue in ODBC

> Key: IMPALA-3149
> URL: https://issues.apache.org/jira/browse/IMPALA-3149
> Project: IMPALA
> Issue Type: Bug
> Components: Clients
> Affects Versions: Impala 2.2, Impala 2.3.0
> Reporter: Jiri Novak
> Assignee: Syed A. Hashmi
> Priority: Minor
>
> For some reason Cloudera Impal does not recognize bind variable in HAVING
> clause.
> If we execute the following simple query using .Net and ADO.Net
> {code:sql}
> SELECT COUNT(address.address_id)
> , address.country
> FROM quest_stage.address address
> GROUP BY address.country
> HAVING (COUNT(address.address_id) > ?)
> {code}
> It returns the following error
> Error:
> {noformat}
> [Cloudera][ImpalaODBC] (110) Error while executing a query in Impala: [HY000]
> : AnalysisException: Syntax error in line 5:
> HAVING (COUNT(address.address_id) > ?)
> ^
> Encountered: Unexpected character
> Expected: CASE, CAST, EXISTS, FALSE, IF, INTERVAL, NOT, NULL, TRUE, IDENTIFIER
> {noformat}
> Bind variable works correctly in WHERE clause. Also the query returns correct
> result if we use a number instead of the bind variable.
