SQL SERVER获取错误文本信息

SQL SERVER获取错误文本信息，BDE、adoquery一直取不到，FDQuery可以了

Some DBMS, like SQL Server, return messages as an additional result set. So, to process messages, the application needs to process multiple result sets. Here is a more complex example, providing status and messages for SQL Server. As you see, we are using TFDMemTable to store result sets with rows.

var
  i: Integer;
begin
  FDConnection1.ResourceOptions.ServerOutput := True;
  FDQuery1.FetchOptions.AutoClose := False;
  FDQuery1.Open(‘select * from Region; print ‘‘Hello‘‘‘);
  FDMemTable1.Data := FDQuery1.Data;
  Memo1.Lines.Add(Format(‘%d rows processed‘, [FDMemTable1.RecordCount]));
  FDQuery1.NextRecordSet;
  if FDConnection1.Messages <> nil then
    for i := 0 to FDConnection1.Messages.ErrorCount - 1 do
      Memo1.Lines.Add(FDConnection1.Messages[i].Message);
end;
