NEEDING HELP: Mass-update a DB2 Table with a Collection?

Ugh. This is my first time performing a mass update to a DB2 table and its proving very challenging. If anyone can assist, I'd be very thanful!

 

Scenario

  • There are 5 blank columns in a DB2 table of 20 fields. We need user input for the 5 blanks columns
  • User filters the table by selecting from Dropdown controls in the app. (<--this works fine)
  • Results are displayed in a Gallery(<--this works fine)
  • User selects records to edit using a Checkbox next to each Record in the Gallery
    • OnCheck Property set to Collect ThisItem (the entire selected record) (<--this works fine, but is it the correct approach?)
    • We end up with a Collection of all items to be Patched to the DB2 table
  • Once all Records are selected, User selects a value, from a Dropdown menu (outside of Gallery) to apply to ALL SELECTED RECORDS
    • OnChange Property sets this selected Value to a variable.
    • We grab the remaining 4/5 fields on the back end (User().Name/Email/etc). 

 

I'm having trouble tying it all together with Patch or UpdateIf statement. 

 

The DB2 table DOES NOT have a Primary Key set so this may be blocking us, but if you could weigh in with your best practice/approach here, it would be very awesome. 

 

Thank you!

Re: NEEDING HELP: Mass-update a DB2 Table with a Collection?

Here is what we ended up using to Patch a DB2 data source with a Collection. Hope this helps you too!

ForAll(
    collection,
    Patch(
        '"<db2.Table>"',
        First(
            Filter(
                '"<db2.Table>"',
                db2TableID = collectionID
            )
        ),
        {
            db2ColumnName: value,
            <repeat:values>
        }
    )
)

        }
