"updateDatabase throws Incorrect syntax near the keyword WHERE error"
i have a simple process that reads a bunch of columns from a database table and finds outlier.
Then i wan to update the same table with the outlier column. The record match should be based on the ID column.
The ID column should play no role in outlier detection. It only exists to help update the right record.
With the process below, i am getting Incorrect syntax near the keyword WHERE" error when viewing results.
What am I doing wrong?

You need to set the role (use Set Role) of the id attribute to id before the outlier detection to avoid it being used as part of the outlier determination.
Does the target table already have a column called outlier?
In the Update Database operator, use the select attributes button to select only id and outlier - this might help.

Yes, the target table does have a column called outlier.
i am using the operator: update Database
Its documentation says there's a parameter called
db id attribute name: The name of the id attribute in the database and the ExampleSet' Range: string; default: 'id'
However, i am not seeing any option to provide this input (see screenshot).

If you select "attribute filter type" within the Update Database operator, you can select the attributes you want to use. Id and outlier are the minimum - make sure you check "include special attributes"

I am using the select "attribute filter type" option. I need all the columns (including id and outlier).
Still that "Incorrect syntax near the keyword WHERE" error.
I notice that i am not seeing any option to set this parameter:
db id attribute name: The name of the id attribute in the database and the ExampleSet' Range: string; default: 'id'
When I switch to Expert mode, i notice a message that says, "1 hidden expert parameter". I suspect this is the parameter that needs to be set. But can't find anyway to set it.
http://nbstoragemahesh.blob.core.windows.net/jbsbsorba/rm2.png
I can't find the parameter but I found it didn't matter. Select the id and outlier attributes (make sure you check "include special attributes" or it won't work) and the database table will be updated. If you include all attributes, the error happens.

Andrew
As a workaround, i have used 'write Database' operator.
So i write into a new table.
Then using an external T-SQL process, i am updating the original table.
Will continue trying to make the original process work.
due to some limitations currently the Update Database operator "id" parameter is actually the attribute selector. The column(s) selected there will be used in the WHERE clause, all other columns will be updated in the DB.
