error=query cannot be pushed down Atwood, Tennessee

ADF(Azure Data Factory) Error: An error occurred in Stored Procedure Activity execution. I created two distributed tables: visits range-partitioned by customer_id with 3 shards, and pages range-partitioned by page_id with 2 shards. Query aborted- the maximum reject threshold (0 rows) was reached while reading from an external source: 1 rows rejected out of total 1 rows processed. (/nation/sensors.ldjson.txt)Column ordinal: 0, Expected data type: PolyBase setup is well documented on MSDN.

SQL Server has been restarted after all the configuration changes. When lineitem is distributed by l_orderkey, the following query fails: select count(distinct l_orderkey) from lineitem group by l_orderkey; ERROR: cannot compute aggregate (distinct) DETAIL: table partitioning is unsuitable for aggregate (distinct) Msg 7421, Level 16, State 2, Line 1 Cannot fetch the rowset from OLE DB provider "SQLNCLI11" for linked server "(null)". . We can configure pushdown optimization in the following ways: Using source-side pushdown optimization: The Integration Service pushes as much transformation logic as possible to the source database.

I couldn't find a case in which joins didn't work, but also couldn't prove they would give correct results under every type of join we have, so to be safe disallowed Solution: Create the external table first and then use INSERT INTO SELECT to export to the external location. Is there any alternative to the "sed -i" command in Solaris? One way to do that is by using Hive which let's us run SQL queries against the big data.

So, to answer your question, yes, this issue includes all count(distincts) which can be pushed down to produce correct results when we know that the table is hash distributed. TH Can There Only be One Context User per Transaction? If the database server fails, it rolls back transactions when it restarts. If you configure a session for full pushdown optimization, and the Integration Service cannot push all the transformation logic to the database, it performs source-side or target-side pushdown optimization instead.

Therefore we should be able to push down the count(distinct) if it is on the distribution column or if the query has a group by on the distribution column.

Pushdown Optimization Error Handling When the Integration Service pushes transformation logic to the database, it cannot track errors that occur in the database. Possible Solution: Coresite.xml's "" property should be KERBEROS (all upper case) as the value.  Customer Scenario: SQL DW is setup with supported HDP Cluster.

And if we produce correct results for that in the range case, I think we should also produce correct results in the hash case (for this join). It generates the following SQL statement to process the transformation logic: INSERT INTO EMP_TGT(EMPNO, ENAME, SAL, COMM, DEPTNO) SELECT EMP_SRC.EMPNO, EMP_SRC.ENAME, EMP_SRC.SAL, EMP_SRC.COMM, EMP_SRC.DEPTNO FROM EMP_SRC WHERE (EMP_SRC.DEPTNO >40) The Integration Reason: CETAS is not a supported statement in SQL Server 2016 for PolyBase.

Sometimes, we can even "push" some transformation logic to the target database instead of doing it in the source side (Especially in the case of EL-T rather than ETL).
