Column in the target Table is now in a unique index, changes in maps?
Hello
just a quick question.
I have a mapping and a column of the target database is now in a unique index. What I have to change something in my map?
I don't think so but if I change something please let me know.
Thank you
Greetings
If the dataset that you load convinces him the uniqueness of the index (which it probably does if the index has been applied to the previously loaded data) then you should not change the mapping.
Oracle running on Oracle Linux 6.4 12.1.0.2.0 database:
During his studies of FUSION with invisible columns, I discovered that invisible columns in the target table cannot be read. Workaround seems to be
MERGE INTO (SELECT <column list> FROM <target table>) AS <alias>
However, the documentation does not seem to allow this. Here are the details.
Test data
> CREATE TABLE t_target(
k1 NUMBER PRIMARY KEY,
c1 NUMBER,
i1 NUMBER invisible
)
table T_TARGET created.
> INSERT INTO t_target (k1,c1,i1)
SELECT 2, 2, 2 FROM dual
UNION ALL
SELECT 3, 3, 3 FROM dual
UNION ALL
SELECT 4, 4, 4 FROM dual
3 rows inserted.
> CREATE TABLE t_source(
k1 NUMBER PRIMARY KEY,
c1 NUMBER,
i1 NUMBER invisible
)
table T_SOURCE created.
> INSERT INTO t_source (k1,c1,i1)
SELECT 1, 1, 1 FROM dual
UNION ALL
SELECT 2, 2, 9999 FROM dual
UNION ALL
SELECT 3, 3, 3 FROM dual
3 rows inserted.
First try
Please note that I have a WHERE clause in the WHEN MATCHED clause. Its purpose is to avoid the update of a row when data are already correct. The WHERE clause is trying to read the invisible column of the target table.
> MERGE INTO t_target o
USING (
SELECT k1, c1, i1 FROM t_source
) n
ON (o.k1 = n.k1)
WHEN MATCHED THEN UPDATE SET
c1=n.c1, i1=n.i1
WHERE 1 IN (
decode(o.c1,n.c1,0,1),
decode(o.i1,n.i1,0,1)
)
WHEN NOT MATCHED THEN INSERT
(k1, c1, i1)
VALUES(n.k1, n.c1, n.i1)
...
Error at Command Line : 10 Column : 12
Error report -
SQL Error: ORA-00904: "O"."I1": invalid identifier
As you can see, I put a subquery after the USING clause so that 'n.i1' would be 'visible', but this is not enough since the 'I1' column in the target table is always invisible.
Second test
> MERGE INTO (
SELECT k1, c1, i1 FROM t_target
) o
USING (
SELECT k1, c1, i1 FROM t_source
) n
ON (o.k1 = n.k1)
WHEN MATCHED THEN UPDATE SET
c1=n.c1, i1=n.i1
WHERE 1 IN (
decode(o.c1,n.c1,0,1),
decode(o.i1,n.i1,0,1)
)
WHEN NOT MATCHED THEN INSERT
(k1, c1, i1)
VALUES(n.k1, n.c1, n.i1)
2 rows merged.
Here I used a subquery in the INTO clause thus, and it worked.
Unfortunately, this does not seem to be admitted in the documentation: IN fact refers to a table or a view as schema objects.
My question is:
How can I refer to invisible columns in the target table without creating a new object? My workaround using a subquery solution seems to work very well, but can I recommend if it is not documented?
Can I replace a "inline view" for a view and still be supported?

But the documentation DO ALLOWS not only! You use a view - a view online and those that can be changed in a MERGE statement.
All versions of the doc for FUSION since 9i specifically say this:
INTO clause
Use the INTO target clause to specify the table or view you are updating or inserting into. To merge the data in a view, the view must be updated. Please refer to the "Notes on the editable views" for more information.
Here are the links for the doc. 9i, 10g, 11g and c 12, ALL OF THEM (the last three), except 9i have this EXACT clause above.
9i doc does not have this specific quote in the INTO clause section, but it doesn't have that quote a little later:
Limitation of the update of a view
You cannot specify DEFAULT when refreshing a view.
You cannot update a column referenced in the ONcondition clause.
merge_insert_clause
The merge_insert_clause specifies the values to insert into the column of the target table, if the condition of the ON clause is false. If the insert clause is executed, then all insert triggers defined on the target table are activated.
Restrictions on the merger in a view
You cannot specify DEFAULT when refreshing a view.
If your "workaround" isn't really a workaround solution. You SHOULD use an inline view if you need to reference a column "invisible" in the target table, since otherwise, these columns are INVISIBLE!
My workaround using a subquery solution seems to work very well, but can I recommend if it is not documented?
Hi all I HAV done an interface for a simple source data transfer to the target. When I run it, the records are stored in the target table. Now, I want to launch the interface (for the same or different source table) and add the records to existing records in the target table.
Kindly guide me, explaining how shud I do the addition in the target table.
Thanks in advance.
Hello
You can use the IKM control add... it will add records...
I have a map where I fill in a column of my target table using a database sequence. Now my mapping is supposed to load the target gradually table. So I need a revenge for update and incremental insert. Now with this differential IKM it compares all the columns to match all colmuns line to understand, it should be an insert or update. Now, the following code shows that when the ROW_WID is loaded with a sequence of database.
If NOT EXISTS
(select 1 from W_LOV_D T
where T.ROW_WID = S.ROW_WID
and ((T.CREATED_BY = S.CREATED_BY) or (T.CREATED_BY IS NULL and S.CREATED_BY IS NULL)) and
Please suggest if there is no other IKM I should use or if there is another way around it without changing the code IKM...
Hi Marc,
Thanks for your reply.
I had solved it. The incremental update process inserts all rows from the source table to I$ table that exists in the target table. It does so by the where sql such as mentioned in my questions as
WHERE THERE is NOT ( . COLUMNS = . COLUMNS)
Now in the incremental update IKM Oracle to retrieve all the columns it uses the substitution with parameter as TABLE TARGET. Due to this column sequence will in the comparison and the request fails. When I used the IKM SQL incremental update it used INTEGRATION TABLE as parameter table to pick up the columns, as I'd mentioned in the target sequence is run, so it does not get the sequence column.
Simple answer: to solve this, use incremental update of the SQL IKM.
I'm not grasp this concept. Would you be able to provide the logic how and why you need to create a foreign key that references a column of the same table?
For example, referencing the schema, SupervisorNo @ here is a FOREIGN KEY to the "EmpNo" column in the same table.
EMPLOYEE (EmpNo, title, Fname, Lname, phone, Email, date of birth, sex, salary, HireDate, OutNo, SupervisorNo @)
Why would you want to do this and how can it be used? If you are filling out the data in the table, and this constraint is enabled, you will not be able to load whatever it is because the "EmpNo" column will be empty.
Any input you can provide me with this would be greatly appreciated. Thank you!

Self-referential integrity constraints
Lets say that we have the table emp with emp_no and mgr_no columns.
Now all managers should also be an employee too. How can I check this when inserting data into this table? I applied auto integrity constraint. It would help me to make sure no handler (doesn't mean no mgr_no) must be registered if this Manager is not an employee of this organization. Which means, I won't be able to enter any mgr_no in the column until and unless that the same employee also is an employee (emp_no from the same table).
I am new to ODI and slowly learning how everything goes in ODI. I came across a problem in either the IE interface is I have a source table in the source of the interface with 10 columns box and in the target box, I have a table with 15 columns. I loaded 10 columns in source with 10 columns in the target, and my question is how the rest of the columns must be loaded with "NA" If no column related to them does not appear in the source table? Please help me solve this.
Thank you.
In the hardcode the mapping section that you want to enter for example "NA" and in the properties panel that execute on the target (in red color).
I developed a scenario in an interface, where I planned keeping the option Truncate as false, right there the data is been going to target without any problems, but when I changed the status of truncate to TRUE, the interface is been run, but the array is not get truncated, rather the data's been loading again to target. (when running manually, the target table is been truncated perfectly) but not in programming.
Can someone help me in this problem.
Thank you
Shakur.
Have you regenerate the scenario in question since you changed the option Truncate. If you have not the regular job must still run the old code
I need to conditionally return a column that said Condition is as if the value in the other column of the same table B is equal to F. I should make A column only when this condition is met. I tried the following code:

Can someone tell me how to extract the date max of the target table.
Thank you.
Azhar
Sorry why again once you are not able to use the aggregator operator to get a max value. You don't need a group of when taking a max value what from a table, unless otherwise specified
Try it with a simple table b table card
table (several itemno)
table b (number maxitem)
Use aggregator and don't put anything in the section of owb agg transformation group. Generate the code and take a look
OWb, I try to update the target table with the game and the update on the same ground is this possible. I'm a match merge error indicating that you cannot update and match on the same ground. But in SQl is my selection
Update table define RFID = 0 where RFID = 1 and ID_processus = 'TEST '.
Can HWO I do this in OWB.
I have check but in the case later (last one) that he warns no error if you can go with it. and I tested it it works
You can check the first case (from where we start) if it has been warned and then try to run.
