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;SQL SERVER获取错误文本信息
