TOracleQuery.Describe - as for TOracleDataset?

[Andrey Maximenko. Ukraine]

Hello!
Does TOracleDataset has some method as TOracleQuery.Describe?
I want to get the field descriptions of a TOraclceDataset without actually executing it.
procedure TOracleDataset.InternalInitFieldDefs and procedure TOracleDataset.InternalOpen are protected.
Thanks.

You can use the FieldDefs for this. For example:

DataSet.FieldDefs.Update;
  for i := 0 to DataSet.FieldDefs.Count - 1 do
    ShowMessage(DataSet.FieldDefs[i].Name);

Hello, Marco!
DataSet.Fields hasn't Update method.
After calling FieldDefs.Update,
FieldDefList.Update, FieldList.Update
I can't use method DataSet1.FindField or DataSet1.FieldByName.
I want to use FindField (FieldByName) to set field's property (PickList, ReadOnly, etc).

You can only use the FieldDefs after calling FieldDefs.Update. There are no Fields yet.

Hello, Marco!

We found that:

for i:=0 to DataSet.FieldDefs.Count-1 do
DataSet.FieldDefs.Items.CreateField(DataSet);
