I am trying to do the differential data load from db2 to PostgreSQL table through InfoSphere Federation Server.
Followed below steps and got the expeption:
SQL1822N Unexpected error code "55000" received from data source "FEDSER".
Associated text and tokens are "This ResultSet is closed.".
Please find the below steps which I followed:
create wrapper jdbc

I am using Postgres version 12, Java version "1.8.0_241"
Please help me to resolve this issue. or once connection get created then I can only create the nickname.
Consider using Db2 11.5 instead of InfoSphere Federation Server which went out of support 2017-09-30 https://www.ibm.com/support/lifecycle/#/search?q=InfoSphere%20Federation%20Server
Db2 11.5 includes inbuilt support for PostgreSQL federation in all Db2 editions including Db2 Community Edition

I can connect to IBM DB2 inside the IBM Cloud Pak for Data, but when I try to run the exact same %sql connection it errors out. What am I missing?
'''%sql ibm_db_sa://un:pw#host:port/db?security=SSL'''

I set up a connection to a Hive server using the Hortonworks ODBC Driver for Apache Hive. Version info is below:
OS: Windows Server 2012 R2 Standard
Hive: 1.2.1000.2.6.5.4-1
Hadoop: 2.7.3.2.6.5.4-1
Hortonworks ODBC Driver for Apache Hive
ODBC Version: 03.80
Driver Version: 2.1.12.1017
Bitness: 64-bit
Locale: en_US
I can run the queries below using the connector that I configured in Teradata SQL Assistant with no issues. I set up my DSN as a linked server in SSMS. However, when I attempt to run the queries in SSMS using openquery, I have some issues. Info on my SQL Server is below:
Microsoft SQL Server 2016 (SP2-CU3) (KB4458871) - 13.0.5216.0 (X64) Sep 13 2018 22:16:01 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows Server 2012 R2 Standard 6.3 <X64> (Build 9600: ) (Hypervisor)
Here is some info on the table that I am querying:
Table Name: instrumentapps_event
Using OPENQUERY, I am capable of querying the Hive DB through SSMS with the following query:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event')
The above query returns the contents of the desired table. However, the query below produces an error:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event WHERE to_date(from_unixtime(UNIX_TIMESTAMP(load_ts,''yyyy/MM/dd''))) >= to_date(''2019-03-01'')')
The error is as follows:
Msg 7355, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "KMhivehttp" supplied inconsistent metadata for a column. The name was changed at execution time.
How can I fix this?
While I'm unsure how to fix the problem that I previously faced (I suspect it to be a bug with the Hortonworks ODBC driver), I did discover a workaround.
Instead of running:
SELECT * FROM OPENQUERY(KMhivehttp,
'SELECT *
FROM dmfwk_gold.instrumentapps_event
WHERE to_date(from_unixtime(UNIX_TIMESTAMP(load_ts,''yyyy/MM/dd''))) >=
to_date(''2019-03-01'')
')
I now use:
SELECT * FROM OPENQUERY(KMhivehttp, 'select * from dmfwk_gold.instrumentapps_event')
WHERE load_ts >= CAST('2019-03-01' AS DATE);
This allows me to avoid any metadata errors.
I am new to Hibernate. Using the 5.2.10 FINAL version connecting to Oracle 11g using the Oracle10gDialect with JPA 2.1 and ojdbc8.jar
I try to access a simple stored procedure taking a String input parameter and output a Oracle SYS_REFCURSOR.
StoredProcedureQuery call = session.createStoredProcedureCall("sp_get_profile");
call.registerStoredProcedureParameter(1, String.class, ParameterMode.IN);
call.registerStoredProcedureParameter(2, Class.class, ParameterMode.REF_CURSOR);
call.execute();
An exception occur when I access the function
ERROR SqlExceptionHelper Invalid column type: 2012
DatabaseException::error=[Error registering REF_CURSOR parameter [2]]
I try to write a simple program connecting to DB with the Oracle Driver only. I will have the same error if I register Types.REF_CUSOR as the output parameter to CallableStatement.
cs.registerOutParameter(2, Types.REF_CURSOR);
And the problem can be solved by changing to OracleTypes
cs.registerOutParameter(2, OracleTypes.CURSOR);
Anyone know what is wrong? I need to fall back to use the traditional SQL programming if I cannot get the stored procedure access success. . . please help.
Finally got it work, I should check the Oracle JDBC document first before implementation.
ojdbc8 should be good for Oracle 12c + JDK8 + JPA2.1 with Oracle12cDialect.
For Oracle 11g, need to use ojdbc6.jar
I solved that issue by debugging OJDBC and Hibernate, the building from sources a patched Hibernate CORE library (5.4.15-Final).
I have patched the method ExtractedDatabaseMetaDataImpl.supportsRefCursors which returns always false.
I am running a SQL query and trying to break the results down into chunks.
select task_id, owner_cnum
from (select row_number() over(order by owner_cnum, task_id)
as this_row, wdpt.vtasks.*
from wdpt.vtasks)
where this_row between 1 and 5;
That SQL works with DB2 10.5 on Windows and Linux, but fails on DB2 10.1 on z/OS with the following error messages:
When I run the SQL from IBM DataStudio 4.1.1 running on my Windows machine connected to the database, I am getting:
ILLEGAL SYMBOL "<EMPTY>". SOME SYMBOLS THAT MIGHT BE LEGAL ARE: CORRELATION NAME. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.18.60
When I run my Java program on a zLinux system connecting to the database, I get the following error:
DB2 SQL Error: SQLCODE=-104, SQLSTATE=42601, SQLERRMC=<EMPTY>;CORRELATION NAME, DRIVER=3.65.97
Any ideas what I'm doing wrong?
In some DB2 versions you must use a correlation name for a subselect, as suggested by the error message:
select FOO from (
select FOO from BAR
) as T
Here "T" is the correlation name.
I have followed the instructions from here and installed the updated plugin. The error has become:

I am using Hive 0.8.1 on OS X Lion 10.7.4.
Is your query as simple as select * from panstats? I suspect that the query is not the problem, but you'll want to confirm that first.
You could try querying that table from a tool like SQuirreL SQL. If that tool also cannot get the data, then it's probably a Hive issue. If it can... then it's probably an issue with iReport or the Hive plugin.
It sounds like Hive is not configured to share metadata. It uses the annoying default configuration with Derby, so outside connections don't get access to your panstats table. I came across this article about configuring Hive earlier this year. It documents using MySQL instead of derby. If that's indeed the problem, then it's just a Hive configuration issue. Following that article would solve things both for SQuirreL and for iReport.
