Appending Data in Columns

Hi Folks,

I'm trying to design a Search engine. We have one table that stores prod_id, attr_cd and attr_val. Some of the products attributes are searchable and some are not. I created a search table prod_id, attr_val. I'm trying to design a trigger that will query our attribute info table, if an attr_cd is searchable throw it into the search table. The problem I'm having is that one product will have several searchable attributes and I want to make the Search table one row for one product. How to append data into a column? Thanks for the help.

In your update if it were a VARCHAR type, then you can do the following

UPDATE table ....
SET column = :0ld||','||:new;

Good luck
Sam
