intouch中如何显示数据库表的内容

dayong657 2014-11-12 07:48:52

如题，搞了一下午也没有成功。很简单的一个问题，intouch项目中控件是MSFlexGrid或者DataGrid。
用了两种方法都不行，一种是调用SQLConnect()连接数据库，再调用SQLSelect()，选择完成后不知道怎么给Grid控件的数据源属性赋值，找也找不到。
脚本如下：

ResultCode=SQLConnect(ConnectionID,"DSN=myDatabase;DB=gprsdb");

IF ResultCode==0 THEN

ErrMsg="No connect error";

ELSE

ErrMsg=SQLErrorMsg(ResultCode);

ENDIF;

ResultCode= SQLSelect( ConnectionID, "temptable","hisTabList" , "","" );

第二种方法从网上找来的，跟vb里使用几乎一样。
脚本如下：

{===建立与MS SQL数据库Pubs连接（用户名：sa，密码：）===} 

DIM connect AS MESSAGE;

DIM strSQL AS MESSAGE;

 DIM ColIndex AS INTEGER; 

DIM RowIndex AS INTEGER; 

DIM ColCount AS INTEGER;

OLE_CreateObject(%myCon,"ADODB.Connection");   

OLE_CreateObject(%myRs,"ADODB.Recordset");ADO{connect="Provider=SQLOLEDB; Data Source=E8INHLY0QRBITBZ; Initial Catalog=gprsdb; User Id=; Password=; ";}

connect="driver={sql server};server=E8INHLY0QRBITBZ;database=gprsdb;uid=;pwd=";

%myCon.Open(connect);    

strSQL="SELECT  top 50 record_time from historytable";

%myRs.Open(strSQL,%myCon,3,3,1);

#MSFlexGrid1.DataSource=%myRs;

运行提示MSFlexGrid1.DataSource赋值属性不对，我都无语了。。。求高人指点。！

好高兴，本人最近做出来了！！！楼主参考一下吧！用的ACCESS数据库，数据记录到表table2中，在把表中的最新10条记录，在控件MSFlexGrid1中显示出来。 SQLConnect( ConnectionId, "DSN=intouch_access" ); SQLCreateTable( ConnectionId, "table2", "" ); SQLInsert( ConnectionId, "table2", "access_database" ); SQLSelect( ConnectionId, "table2", "access_database_1", "", "" ); NumRows=SQLNumRows( ConnectionId ); SQLDisconnect( ConnectionId ); #MSFlexGrid1.cols=10; #MSFlexGrid1.rows=11; #MSFlexGrid1.row=0; #MSFlexGrid1.col=0; #MSFlexGrid1.Text= "序号"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=1; #MSFlexGrid1.Text= "日期"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=2; #MSFlexGrid1.Text= "时间"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=3; #MSFlexGrid1.Text= "型号"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=4; #MSFlexGrid1.Text= "电压"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=5; #MSFlexGrid1.Text= "频率"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=6; #MSFlexGrid1.Text= "空载电流"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=7; #MSFlexGrid1.Text= "空载功率"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=8; #MSFlexGrid1.Text= "耐压值"; #MSFlexGrid1.CellAlignment=4; #MSFlexGrid1.col=9; #MSFlexGrid1.Text= "是否合格"; #MSFlexGrid1.CellAlignment=4; OLE_CreateObject(%table2Cn,"ADODB.Connection"); %table2Cn.Open("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=D:\test.mdb; " ); DIM strSQL AS MESSAGE; DIM ColIndex AS INTEGER; DIM RowIndex AS INTEGER; DIM ColCount AS INTEGER; OLE_CreateObject(%table2Rs,"ADODB.Recordset"); strSQL="Select * from (Select top 10 * from table2 order by 序号 desc) order by 序号 asc"; %table2Rs.open(strSQL,%table2Cn); IF %table2Rs.EOF==0 THEN %table2Rs.Movefirst(); ELSE ErrorMsg="Error!"; ENDIF; IF %table2Rs.EOF==0 AND NumRows <= 10 THEN ColCount=10; RowCount=NumRows; FOR RowIndex=1 TO NumRows #MSFlexGrid1.Rows=RowCount+1; #MSFlexGrid1.row=RowIndex; FOR ColIndex=0 TO ColCount - 1 #MSFlexGrid1.col=ColIndex; %Field=%table2Rs.Fields.Item(ColIndex); #MSFlexGrid1.Text= %Field.value; #MSFlexGrid1.CellAlignment=4; NEXT; %table2Rs.Movenext(); NEXT; ENDIF; IF %table2Rs.EOF==0 AND NumRows > 10 THEN ColCount=10; RowCount=10; FOR RowIndex=1 TO 10 #MSFlexGrid1.Rows=RowCount+1; #MSFlexGrid1.row=RowIndex; FOR ColIndex=0 TO ColCount - 1 #MSFlexGrid1.col=ColIndex; %Field=%table2Rs.Fields.Item(ColIndex); #MSFlexGrid1.Text= %Field.value; #MSFlexGrid1.CellAlignment=4; NEXT; %table2Rs.Movenext(); NEXT; ENDIF; %table2Rs.close(); %table2Cn.close(); OLE_ReleaseObject(%table2Cn); OLE_ReleaseObject(%table2Rs);
