TFDMemTable & TSQLTimeStampOffsetField

[MathiasBurbach 0]

Hello Folks,

 

we are trying to use the TSQLTimeStampOffsetField defined in Data.DB.pas for a TFDMemTable. We created a static field list and tried to open the TFDMemtable. We run into an error:

Quote

Type mismatch for field 'Start', expecting: TimeStampOffset actual: Unknown.

The call stack ...

Data.DB.DatabaseError('Type mismatch for field ''Start'', expecting: TimeStampOffset actual: Unknown',$1767270)
Data.DB.DatabaseErrorFmt('Type mismatch for field ''%s'', expecting: %s actual: %s',(...),$1767270)
Data.DB.TDataSet.CheckFieldCompatibility($1758D20,$17FFE10)
Data.DB.DoBindFields($17FFF60)
Data.DB.TDataSet.BindFields(True)
FireDAC.Comp.DataSet.TFDDataSet.InternalOpen
Data.DB.TDataSet.DoInternalOpen
Data.DB.TDataSet.OpenCursor(???)
FireDAC.Comp.DataSet.TFDDataSet.OpenCursor(False)
Data.DB.TDataSet.SetActive(???)
FireDAC.Comp.DataSet.TFDDataSet.SetActive(???)
Data.DB.TDataSet.Open
FMain.TfrmMain.FormCreate($1780E30)
Vcl.Forms.TCustomForm.DoCreate
Vcl.Forms.TCustomForm.AfterConstruction
System._AfterConstruction($1780E30)
Vcl.Forms.TCustomForm.Create(???)
Vcl.Forms.TApplication.CreateForm(???,(no value))

... indicates that the TDataSet.CheckFieldCompatibility method points to a FieldDef for the column Start, for which the data type is unknown. I have tried to setup the FieldDefs first before opening the TFDMemTable but that did not help either.

 

Why can I define a field of type TSQLTimeStampOffsetField but when I open the dataset the data type is unknown? I am using Delphi 11 Alexandria Version 28.0.42600.6491.

 

Thanks for a short answer in advance.

 

Salut,

  Mathias
