Im trying to update some values (via django) at a table on Postgres that contains a Generated column.
This is the error im getting:
column "xx_xx" can only be updated to DEFAULT
See complete error here
You cannot edit generated column in a way other columns are saved/updated
As PostgreSQL documentation states
A generated column cannot be written to directly. In INSERT or UPDATE commands, a value cannot be specified for a generated column,
but the keyword DEFAULT may be specified.

Context:
I have a dates table that I pulled in just by checking its box in the add data wizard which generated this
= Source{[Schema="dbo",Item="vw_ReportDates"]}[Data]
then I renamed the column ReportDayNo to DayOfReportMonth and I now get to see DayOfReportMonth in the data model but I get an error saying ReportDayNo doesn't exist. I'm not sure what to do here, the code doesn't explicitly call out for ReportDayNo so I'm not sure where to correct this.
Question:
how do I tell Power Query this column no longer exists?
You have following options (for Table.RenameColumns step):
Delete this step completely (if ReportDayNo was only column you renamed);
Delete the chunk {"ReportDayNo", "DayOfReportMonth"} from your step (if there are other columns you renamed);
Add 3rd argument MissingField.Ignore to your Table.RenameColumns function. More info:

Iam new to Informatica,I have to add two new fields(AREA,AMT) to an already existing SQL query in Informatica. After this should I manually add the source qualifier port with these two fields?
What I did was:
1) Changed the query in SQL qualifier in Mapping designer- added the two new fields, saved the mapping
2) Refreshed the workflow in Workflow designer
3) Monitored the result in Workflow Monitor which was successful.
Now, the resulting text file has the new field values but no column header names. Hence the column header values are shifted resulting in column name and value misalignment.
Any help on this is appreciated.
Thanks!
YES you should manually add the two ports to the Source Qualifier. The number of fields selected in the SQL query should match the number of ports in the Source qualifier which are linked to the next transformation.
Interestingly Informatica maps the fields from the SQL query to the Source qualifier output links instead of Source Qualifier ports. So the first column in the SQL query gets mapped to the first link, second column to the second link and so on.
For your header issue, you should let us know how you are generating the headers for the output file. If you are using "Use header command output" option in the target file session properties for generating headerthen you have edit the command to create header for there two new ports as well.
while updating a record using MRU its failing with below error.
1 error has occurred
Current version of data in database has changed since user initiated update process. current row version identifier = "C5F3645B026AA5646C00DC7B631C4D19" application row version identifier = "6A9323B62F641015FA4601421DFB03DE" (Row 1)
This is strange because I do not see any change in the data at backend.
Any help will be highly appreciated.
Thanks.

If you're using a tabular form, check your query, then check the item. The item must match with the correct column in a database that is updatable.
Make sure that your column aliases match your column names (for updateable columns).
I had the same problem, the problem in my case that detail table has composite primary key,
so in application > column > Primary KeyPrimary Key
property must all primary key field enable , not only one field.
I am facing an issue where I am getting the below error while inserting a record in the table via Siebel Operation step.
Here the error is showing for field which is based on a picklist. Could anyone please suggest why i am getting this error:
SBL-DAT-00225: The value entered in field District of buscomp Contact_Address_LT does not match any value in the bounded pick list PickList Comm Resolution.
SBL-BPR-00100: This error is returned when the workflow/task is executing the Siebel Operation business service.
I am aware that this happens when the value is not defined in the picklist. But i have verified this, and LOV is having the value which I am trying to get insert.
This error is quite common. And could happen for a couple of reason.
As you have mentioned, that you have already checked the value which is getting inserted is already there in the LOV defined for the picklist.
I have recently faced this error, and spent hours to debug it. Try below to sort your problem.
Check for the below points:
1) Check for the pick map for this field, check if any contraint field is also present in it.
2) If yes, then check those constraint field is also getting inserted in same Siebel Operation step. Siebel does not follow sequence in the input argument. So if this is the case do step 3 to resolve your issue.
3) Split the insert statement into 2 parts, 1 where you insert the record with the values which is present in the pick map constraint and then update the same record. This will ensure that all the required field are populated.
Solution from 8.1.1.4 is to add parameter into OM's config file, e.g fins.cfg:
[Task]
ProcessArgAsc = true

I pretty new to APEX and I'm having a bit of trouble working with my first Tabular form. The table I've linked it to is fairly simple. The columns are as follows:
Primary key representing an internal
code for a college major
Foreign key representing the "real"
code for the college major
Description for the college major
The user that inserted/updated the
row in the table
The date the row was inserted/updated
At the moment, I'm facing two problems.
I want the user to be able to specify their own primary key for the row but not to be able to change any existing primary keys. When I specify the column type as "Text Field" users are able to edit existing rows' primary keys and it also seems to break the report when trying to add a new row as I get a checksum error.
I would like the user and date
columns to default to the currently
logged in user and the current date,
but specifying default values for
either of these columns also seems
to cause syntax/SQL errors. Does
anyone have any examples of how to
use the default value functionality
for a column? Fixed. I can just use SYSDATE as a value on it's own when specifying the PL/SQL type for default. Username can be obtained through functions in APEX_UTIL
Perhaps you could use 2 conditional fields. If the field value is null, display the edit box, if the field value is not null display the display-only field.
