JSON序列——根据JSON生成事务性SQL
procedure TForm1.Button5Click(Sender: TObject); begin var json: string :='' + '{'+ '"table":"tunit",'+ '"rows":'+ '['+ '{"action": "modify", "original": {"unitid":"11","unitname":"个"}, "current": {"unitid":"11","unitname":"中"}},'+ '{"action": "delete", "original": {"unitid":"66","unitname":"国"}},'+ '{"action": "insert", "current":{"unitid":"13","unitname":"人"}}'+ ']'+ '}'; var serial: TynJsonCross := TynJsonCross.Create; try Memo1.Text := serial.JsonToSql(json); finally serial.DisposeOf; end; end;
生成的事务性SQL:
update tunit set unitid='11',unitname='中' where unitid='11' and unitname='个' delete from tunit where unitid='66' and unitname='国' insert into tunit (unitid,unitname) values ('13','人' )
