  end;

  when i create TSQLModel as follow, it failed with message "Access violation ad address 007CC7F4 in module 'project.exe', Read of address 00000004".
 

 myModel := TSQLModel.Create([Ttjxx],'');

  but many simple TSQLRecord s work fine.

  thanks.

Re: are there any table limitations?

it stoped at TSQLModelRecordProperties.Create of mORMot.pas.

 

  constructor TSQLModelRecordProperties.Create(aModel: TSQLModel;
  aTable: TSQLRecordClass; aKind: TSQLRecordVirtualKind);
  var f: integer;
  ...
  fProps := aTable.RecordProps;          <------------------stoped here.
  ...

Re: are there any table limitations?

Try to change the MAX_SQLFIELDS in SynCommons.pas.
By default, it is 64.
