Hello,

Using the UpdateRowsCommand, you need to indicate what row you want to update in addition to the specific field for that row.

If you look at the API docs here:

https://www.labkey.org/download/clientapi_docs/java-api/org/labkey/remoteapi/query/UpdateRowsCommand.html

https://www.labkey.org/download/clientapi_docs/java-api/org/labkey/remoteapi/query/SaveRowsCommand.html

You'll see the example:

  //Update Rows Command
  UpdateRowsCommand cmdUpd = new UpdateRowsCommand("lists", "People");
  row = new HashMap<String,Object>();
  row.put("Key", newKey);
  row.put("LastName", "Test UPDATED");
  cmdUpd.addRow(row);
  resp = cmdUpd.execute(cn, "PROJECT_NAME");

This allows the specific row to be updated and just that specific field for that one row.

Regards,

Jon
