RowId questions

I am planning to use random number generator to populate Rowid.

  1. Is there a max size of rowid ( maximum characters in rowid)

  2. Is there any issue in using updateFromXML while using randomly generated rowid, ie does updateFromXML use rowid to decide which row in grid to update?
    Because same db row can have diff rowid next time I get it from DB as I am using random number generator.

As DB row can appear twice in a table so I am unable to use DB id as row id.

Hello

  1. There is no max size of row id

  2. does updateFromXML use rowid to decide which row in grid to update?
    Yes, it does. To update some row with updateFromXML method you should retun xml with row id the same as in grid. Without it it not possible to determine which row should be updated
