Hi,

Is there a way to disable the Required fields option with the AutoInc type fields ?

Create a table with an autoinc field (+ other test fields set to NOT NULL).
Build a delphi project with MyDAC 4.x.
Set the TMyquery.Options.Requiredfields to TRUE
Add a grid, navigator bar... Compile and run.

Insert a new record, fill all fields (except the Autoinc field).
Post : exception is raized : field 'My AutoInc field' must be filled

Yes, just add to MyQuery.AfterOpen event handler something like this

Code: Select all

  for i := 0 to DataSet.Fields.Count - 1 do
    if DataSet.Fields[i].AutoGenerateValue = arAutoInc then
      DataSet.Fields[i].Required := False;
