I want to create a target table in Oracle using Informatica. But I see a fatal execution error saying table does not exist.
I don't wanna have to create a table each time I execute a task in Informatica.
Please help!

You will need to create new table only once before running the workflow(if the table is not already created).

Is it possible to create a hive view on top of a nonexistent hive table or views?. This ability will help us deploy the hive DDL without any order at the time of refresh (migrating tables or views from one environment to another). In our environment, we have views built on top of another view. If we deploy them in any order, with the default setup some of the views may fail saying the underlying table/view doesn't exist. Looking to see if we can turn off the metadata lookup from hive metastore so that the type checks are not done at the time of view creation. It can be enforced after the deployment or at the time of querying the view for data retrieval because by that time all the views/tables will be completely deployed and there won't be any type checking related errors.
I checked on the internet for pointers but I couldn't find any. Any suggestions in this regard will be helpful to us.
Thanks in advance.
Add IF NOT EXISTS to all create statements and run all several times until errors disappear.
If executed 2 times in the wrong order like this, second run will succeed without any error:
drop view if exists my_view;
create view if not exists my_view as select from table1; --fails first time, succeeds on second run
drop table if exists table1;
create table if not exists table1(id int);
I am trying to utilise the database copy in Oracle SQL Developer, specifically the Objects Copy to copy data from a table in one database to the same table in another database.
I am trying to copy data from one table on a database, to the exact same format table on another database. See below for log output.
When doing this I come up with the following error:
Copy Option: Objects
Copy Source Connection: DATABASEA
Destination Connection: DATABASEB
DDL Objects: Views Tables Materialized Views
Data Objects: Tables Table X
Object Where: PROCESS_DATE = '2017-12-31'
Copy DDL: No
Copy Data: Yes
Append Existing Objects
--- START
--------------------------------------------------------------------
Skipping Table X
--- END --------------------------------------------------------------------–
I am following the steps outlined here: http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/sqldev/r31/DatabaseCopy/DatabaseCopy.html
I was able to perform a data copy before I got a new laptop, using the exact same software.
I would be grateful for any advice on how to fix this issue.
In my case, the root cause of this issue was a previous attempt to copy this table which failed and SQL Developer failed to roll back the changed - even though I selected the "Cancel and rollback" option. As a result, the table was deleted and the second attempt to copy the table data without DDL was simply skipped - without any error message or explanation. IMHO, the database or SQL Developer should rather output an error message.
Eventually, I was able to resolve the issue by copying the DDL, too.

I want to execute a t-sql statement as one step in a work flow:
truncate table dbo.stage_customer
I tried create a mapping, add a sql transformation on it. Input above query in sql query window. I added the mapping to a workflow of just start, the mapping, and the end. When I validate the flow I got this error:
The group [Input] in transformation xxx must have at least one port
I have no idea what ports are needed since this (the truncate statement) basically doesn't need input or output.
Use your query " truncate table dbo.stage_customer" in Pre-SQL command
As Aswin suggested use the built in option in the session property.
But in the production environments user may not have truncate table access for the table in a database. In this case, informatica workflow will fail if you check the truncate target table option. It is good to have a stored procedure to truncate the target table and use that stored procedure in informatica mapping to avoid workflow failures in case of user having no truncate access to the database.
if you would like to truncate a target table before loading why don't you use the in-built option present in session properties?
goto workflow manager-> open session->mapping tab->click on target table listed left side->choose the property "Truncate table option" just enable it
to answer you question, I think you have to connect at least one input and output port into SQL transformation (because it is not unconnected). Just create dummy ports and try again

I've been receiving backups from an Oracle database into my Oracle database for 2 years now. My company is running version 10.2.0.1.0 and we are receiving the exports from version 12.1.0.2.0. They are using expdp and I'm using impdp. I added a new column into my database, using this script
ALTER TABLE CONTAINERS
ADD ("SHELL" NUMBER(14, 6) DEFAULT 0 );
After running the above on both databases now when they send an export to me the table in question will not import. I receive the following error.
ORA-31693: Table data object "PAS"."CONTAINERS" failed to load/unload and is being skipped due to error:
ORA-02354: error in exporting/importing data
ORA-02373: Error parsing insert statement for table "PAS"."CONTAINERS".
ORA-00904: "SYS_NC00067$": invalid identifier
This error has been going on for a about two weeks, I have tried to resolve the problem multiple ways, this is my last resort as it were.
Any help is greatly appreciated.
Did you try to track down SYS_NC00067? It looks like a system-assigned column name. This sometimes happens when you add a function-based index. Did you create a function-based index on Shell?
I'm new to both Oracle and Informatica.
Currently working on a small task where I need to select all records from the source table, filter the results to get only records where field1='Y' and finally insert new rows into the target table that contains only src.field2 and src.field3 values.
These 2 fields are used for the PK and for the Index of the target table.
So i get an error in Informatica:
"ORA-26002: Table has index defined upon it"
I rather not dropping the index? is there a work around?
I've tried alter index to "unusable" but I got the same error.
Please advice.
Thanks.
Try to use Normal load mode instead of Bulk. You can set in session properties for the target.
