Re: Patch a Collection

You are welcome.

The way I understand it, it is cleaner to use AddColumns instead of ForAll when you just need to calculate a value.  I reserve ForAll for when there is a real need to use actions.

Re: Patch a Collection

You are right, @Mike8, only the second part.

Here is the first part, with a bit of a cheat...

ClearCollect(Collection1,{Letter:"A",Number:1},{Letter:"B",Number:2},{Letter:"C",Number:3});
ClearCollect(Collection2,{SecondNumber:4},{SecondNumber:5},{SecondNumber:6});
ForAll(Collection2, Patch(Collection1, Last(FirstN(Collection1, SecondNumber-3)), {Number: SecondNumber}))

If you don't want to cheat, just add an index to both collections.

Re: Patch a Collection

Perfect. Thank you again @Meneghino.

Especially your first answer about the second part of my question really helped me.
I was using this:
ClearCollect(Collection3, AddColumns(Collection1, "New_column", Collection2.SecondNumber))
and I had the Collection2.SecondColumn in every record in a nested structure.
Problem solved. 🙂

Re: Patch a Collection

Hi @kullurumanoj

I believe the error is related to your table structure.  The SQL table should have a primary key defined.

For example, see here:

Re: Patch a Collection

Re: Patch a Collection

What happens depends on the second parameter of the Patch.

Use defaults to create a new record, or a simple record with primary key values to edit an existing record.

Like this:

Patch(DataSource, {ID: 123}, {TextColumn: "Foo"})

PS You can get better performance if you avoid the use of Defaults():
