Column to Table link

Question

Hi,
I have a question about what seems to be a little oversight within the HTMLDB product. Having said that I hope it something I have missed rather then an oversight.
We keep data in tables on buildings, floors, components etc. Over this table structure we use object views - so we have building object view, floor object view etc. A lot of the data in our object views is derived from the same tables (e.g., the asset table is common to both building and floor object views); and in additional other columns some just happen to have the same name (e.g. short_name).
In the end, for example, the floor object view an "asset number", and the building object view also has an "asset number". I.e., the column names in the various views are identical.
The problem occurs when I create a screen using multiple "form" regions that operate on the different object views I get many "duplicate" item names. This internal HTMLDB identification problem is easy to rectify - just rename the items with a prefix. However, the main issue is that the DML processes that populate these items appear only to work on the base column names within the object views.
Hence if I have P5_BUILD_ASSET_NO and P5_FLOOR_ASSET_NO then BOTH are populated with the same data when a process that populates say Building data runs. Hence I get on the following after running the Fetch row from Building process:
REGION 1
Building Name: ABC Towers
Building Asset #     : 2222
REGION 2
Floor Name: ABC Towers (incorrect!)
Floor Asset #: 2222 (incorrect!)
And after running the Fetch row from Floor process I get:
REGION 1
Building Name: Floor 12 (incorrect!)
Building Asset #     : ABC-9998 (incorrect!)
REGION 2
Floor Name: Floor 12
Floor Asset #: ABC-9998
I cannot find a way to prefix the table name to the column name - for it seems that the processes are only interested in column-names. This would mean my only possible resolution would be to rename all the columns in the object-views and make them unique (possibly by adding a unique table prefix to the column names). However, this would appear to be a large oversight, and I am hoping that I have just missed something basic.
Many thanks.

Thanks for the detailed problem description.
The issue is very simple, you seem to have multiple "Automated Row Fetch" defined on the page. HTML DB supports only 1 Automated Row Fetch process per page.
If you need to fetch data from multiple tables, just write your own Row Fetch processes using the appropriate SQL.
select col1,col2,col3,...
into :P1_COL1,:P1_COL1,:P1_COL3,...
from ...Hope this helps.
