How to MERGE when the target table contains invisible columns?
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?
I get emails when the subject line contains square boxes. I tried to create a message for when rule the subject contains these square boxes, but cannot do so.
Any suggestions?
Thank you.
Then, it will not work. Unless the messages are always of the same address, or a domain, so the only option I see is of filter in your mail.
Start with the only rule of AddressBook and you receive a message that you want people not in your address book (E-mail from companies, bills, your ISP, etc), you can add them to the rule.
Tools | Message rules | Mail | New.
Box 1 - Where the From line contains people {check it out}
Box 2 - Check: delete it & stop processing more rules if you want messages not in the address book to go to deleted items, or you can create a spam folder and direct them here.
You can choose to delete the server, but be careful because you never have messages downloaded to any folder, if you choose this option.
Box 3 - Click on the blue words contains people
Click on the first address to select it. Scroll to the end and hold down the SHIFT key while you click the last address. This will highlight all. Right-click on it and click on from the menu that appears.
Now, click Options and choose: Message * contains no of * the people below in the top of the page Options area, then choose: Message corresponds to one of the people below in the background Options box.
OK your way out of the new rule.
Now, only the addresses that you entered will be uploaded to your Inbox. You won't see other emails.
Remember, if you add a person to your address book, you must add to the rule. It will not automatically be added.
Can someone tell me how to extract the date max of the target table.
Thank you.

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
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 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
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.
How can I write in a table cell (row, column appear) in a database using LabVIEW Database Toolkit? I use Ms Access. Suppose I have three columns in a table, I write 1 row of the 1st column, then 1st rank of the 3rd column. The problem I have is after writing the 1st column of 1st row, the reference goes to the second row, and if I write in the 3rd column, he goes to the 2nd row 3rd column. Any suggestion?
When you perform a SQL INSERT command, you create a new line. If you want to change an existing line, you must use the UPDATE command (i.e. UPDATE tablename SET column = value WHERE some_column = some_value). The some_column could be the unique ID of each line, date and time, etc.
I don't know what is the function to use in the Toolbox to execute a SQL command, since I do not use the Toolbox. Also, I don't understand why you don't do a single INSERT. It would be much faster.
Hi all Can I combine the records in the nested table I have a table with 2 colum: col_1 and col_2 col_1: corresponds to the id (varchar2) col_2: is a column nested with the type of table (sub_col_1 (number), sub_col_2 (number))
for example: I have 2 accounts table ('a', (1,2)) and ('b', (3,4)))
what I want is merged into this table with values ('a', '4.5')) + ('c', (6,7)) IN a single statement
What I should have after this operation ('a', (1,2,4,5)) + ('b', (3,4)) + ('c', (6,7)). Can I do this?
CREATE OR REPLACE TYPE TEST_TYPE AS OBJECT(SUB_COL_1 NUMBER, SUB_COL_2 NUMBER) ;
CREATE OR REPLACE TYPE TEST_TYPE_TABLE IS TABLE OF TEST_TYPE;
CREATE TABLE TEST_MERGE_NESTED_TABLE (COL_1 VARCHAR2(1 CHAR), COL_2 TEST_TYPE_TABLE)
NESTED TABLE COL_2 STORE AS COL_2_NESTED;
INSERT INTO TEST_MERGE_NESTED_TABLE VALUES('a',TEST_TYPE_TABLE(TEST_TYPE(1,2) ));
INSERT INTO TEST_MERGE_NESTED_TABLE VALUES('b',TEST_TYPE_TABLE(TEST_TYPE(3,4) ));

Actually, no. All content of the nested table is first removed (for the given FK), then the result of the MULTISET UNION is reinserted.

9 when not matched then insert (col_1, col_2)

Customer heading there source of EBS 11.5.10 in R12. They are BIApps ODI. 7952 version. Since then, all mappings there are customized they may not disturb on support of Oracle BIApps is concerned. Now, we need to know how many ODI mappings there source EBS is the 11.5.10 in R12 migration and we can only target mappings accordingly.
So, please give me with entries below:
(1) any request for metadata that will give me the information of the source tables table and target them in against an if-same interface that the source of the main interface is another interface. (2) what are the other stuffs that I need to look at from the point of view of the mapping changes when the source is upgrading.e.g. only change the source table is enough or I need to focus on other animals. I feel she's boiling down to create a separate source for R12 adapter.
Kind regards Snehotosh
First open the designer-> models and check which model has got the mapping of the eBS. Get this code with this TERRIBLE application
SELECT count (distinct i_pop) of SNP_POP_COL where I_POP_COL in ( Select i_pop_col in the SNP_POP_MAPPING where i_source_tab in ( Select i_source_tab in the SNP_SOURCE_TAB where i_table in) Select i_table in the SNP_TABLE where I_MOD in (select i_mod in the SNP_MODEL where mod_name = "PUT_HERE_YOUR_NAME") ) ) );

What is the behavior of a cFP-2220, if it is configured to use DHCP and it gets a contact with a BOOTP server, which happens to have a cleared BOOTP table? Always starts the RT app (stop over TCP is set to False) and function normally, but with a link-local address?
Is there a difference between having online with a DHCP server and using a BOOTP server?
We have a case where one such controller seems to freeze upwards, the status LED starts flashing 4 times in a row. We cannot recreate it with a DHCP server.
(This particular case is a bit special because it also involves an application that will try to reconfigure the controller to static (using the System Configuration API 5.0) IP if it does not get a valid IP address in the DHCP boot AND it has a valid IP address of a previous start saved in an INI file, and it is difficult to say exactly when the accident occurred... But there is a difference in the startup behavior to predict?)
FYI - this issue is now explained and fixed in part in another thread here on the forum:
