DATASANP 如何访问服务器函数

服务器端：

1、创建DATASANP 服务器。

2、添加，Sqlconnettion,clientdataSet,DataSetProvider.设置好参数。

3、在 ServerMethodsUnit1 中创建 function recordCount(Sql:string):integer;

function TServerMethods1.recordCount(Sql: string): integer;
begin
if studentTable.Active then
studentTable.Close;
studentTable.CommandText:=sql;
studentTable.Open;
result:=StudentTable.RecordCount;

end;

客户端：

放一个edit控件。及Sqlconnettion，clientdataSet，DSProviderConnection，分别这好这三个的参数。

type
TForm1 = class(TForm)
Button1: TButton;
btn1: TButton;
SQLConnection1: TSQLConnection;
ClientDataSet1: TClientDataSet;
DSProviderConnection1: TDSProviderConnection;
ClientDataSet1id: TIntegerField;
ClientDataSet1name: TStringField;
ClientDataSet1shuxue: TFMTBCDField;
ClientDataSet1yuwen: TFMTBCDField;
edt1: TEdit;
procedure Button1Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
procedure btn1Click(Sender: TObject);

private
FServerMethods1Client:TServerMethods1Client;//定义一个属性，来获取TServerMethods1Client
function GetServerMethods1Client:TServerMethods1Client ;//FServerMethods1Client  的READ
{ Private declarations }
public
property ServerMethods1Client:TServerMethods1Client read GetServerMethods1Client write FServerMethods1Client;//发布属性
{ Public declarations }
end;

var
Form1: TForm1;

implementation

{$R *.fmx}
{$R *.LgXhdpiPh.fmx ANDROID}
{$R *.NmXhdpiPh.fmx ANDROID}
{$R *.SmXhdpiPh.fmx ANDROID}

procedure TForm1.btn1Click(Sender: TObject);
var
ServerMethod1:TServerMethods1Client;
begin
ServerMethod1:= ServerMethods1Client;
edt1.Text:=IntToStr(ServerMethod1.recordCount(‘select * from student‘));
end;

这BOLG插图太方便了，截图后还要保存，再插入，太麻烦了。。
