get column info when onChange update

[railty]

is it possible to get column info when onChange update? ie, can you pass a fromColumnIndex, toColumnIndex in the operations, only needed for update opertion?

This will help if user want to update the server data, we need know the column in the sql

Hello @railty ,
You might want to look at this example first.
Usually, you do not need to know which columns were updated, just update the entire row. And if you really need to know, you can compare the row to the previous version of the row.

The reason this information is not available is that a column can update an entire row, not necessarily just a single key. And multiple columns could update the same key, so their is no 1-1 relationship between columns and key.
