Question
Column Populator utility alternative
For some reasons, column populator utility is not successful in our environment. We are working on it through a Pega SR. But my question here is on an alternative approach.
If we expose a new column, say ColumnA, in our work table, can we use a simple update query like below to populate the column values?
Update <WorkTable> Set ColumnA = pr_read_from_stream('.ColumnA', pzInsKey, pzPVStream)
We can also control the magnitude using 'where' clause on create date column. Does column populator utility does something extra which we may lose by following query approach?
Thanks Vikas for your thoughts on this one.
Option 1 is not applicable to Production environment. Considering Production would have millions of records, I think its better not to do it using optimize wizard.
Option 2 seems good, however this will also do similar thing as I have mentioned in my option.
Do you see anything wrong with the query I mentioned in the post?
Again, I really appreciate your thoughts on this one.
Accepted Solution
PRPC recommends below two approaches to populate the values for explicit columns.
- Populating database columns using the column populator . Refer following article for more details
- Populating database columns by using the service enabled column populator utility. Refer following articles for more details

You can follow either of above approaches.
Hi Manish,
One option is that you can optimize the respective property in your work table.
This will automatically populate the data in the table.
Other option that you can try is use BIX to extract the data in another DB table and then you can copy the data from this table to the exposed column of your work table.
