Scott Wallace updated TEIID-4343:
---------------------------------
Description:
I'm getting an error using the With clause in Teiid connecting to Impala
{code}
with t as (select * from schema_name.table_name)
select * from t;
{code}
Error:
{code}
org.teiid.runtime.client.TeiidClientException: java.lang.RuntimeException: Remote
org.teiid.core.TeiidProcessingException: TEIID30504 warehouse: 11300 TEIID11008:TEIID11004
Error executing statement(s): [Prepared Values: [] SQL: WITH t (col1, col2, col3) AS
(SELECT g_0.`col1`, g_0.`col2`, g_0.`col3` FROM schema_name.table_name g_0) SELECT
g_0.col1, g_0.col2, g_0.col3 FROM t g_0]
Elapsed Time: 0 hr, 0 min, 0 sec, 841 ms.
{code}
Taking the prepared statement and executing against Impala directly, succeeds without any
issues.
Is the With clause supported in the Impala translator?
was:
This is somewhat related to TEIID-3743, which added support of multiple count distinct
metrics. We have a requirement to allow multiple count distinct metrics grouped by common
attributes.
Currently, we get a failure as follows:
{noformat}org.teiid.runtime.client.TeiidClientException: java.lang.RuntimeException:
Remote org.teiid.core.TeiidProcessingException: TEIID30504
vw_impression_click_transaction_process_date_detail: 500051 TEIID11008:TEIID11004 Error
executing statement(s): [Prepared Values: [] SQL: SELECT g_0.process_date_key,
SUM(g_0.num_clicks), SUM(g_0.num_impressions), COUNT(DISTINCT g_0.orderid), COUNT(DISTINCT
g_0.`hash_tid`), SUM(g_0.sales) FROM
detail.vw_impression_click_transaction_process_date_detail g_0 WHERE g_0.process_date_key
>= '2016-05-22' AND g_0.process_date_key < '2016-05-23' AND
g_0.advertiser_key = 12345 GROUP BY g_0.process_date_key]
{noformat}
To allow this request to succeed, we could have translator write that Impala query as:
{noformat}
select nvl(v1.c1,v2.c1), nvl(v1.c2,v1.c2), nvl(v1.c3,v1.c3), v1.c4, v2.c5,
nvl(v1.c6,v1.c6) from (
SELECT g_0.process_date_key as c1,
SUM(g_0.num_clicks) as c2,
SUM(g_0.num_impressions) as c3,
COUNT(DISTINCT g_0.orderid) as c4,
SUM(g_0.sales) as c6
FROM detail.vw_impression_click_transaction_process_date_detail g_0
WHERE g_0.process_date_key >= '2016-05-22'
AND g_0.process_date_key < '2016-05-23'
AND g_0.advertiser_key = 12345
GROUP BY g_0.process_date_key
) v1 inner join
(
SELECT g_0.process_date_key as c1,
SUM(g_0.num_clicks) as c2,
SUM(g_0.num_impressions) as c3,
COUNT(DISTINCT g_0.`hash_tid`) as c5,
SUM(g_0.sales) as c6
FROM detail.vw_impression_click_transaction_process_date_detail g_0
WHERE g_0.process_date_key >= '2016-05-22'
AND g_0.process_date_key < '2016-05-23'
AND g_0.advertiser_key = 12345
GROUP BY g_0.process_date_key
) v2 on v1.c1 = v2.c1;
