}
if (i>=0 && j >= 0) {

这样,可以很方便的在Web页面上显示数据表了。
会web编程(在现在的程序开发中占有很大的比重)的都知道其实是一个HTML文本,采用Javascript来初始化窗口布局,加粗的部分是数据连接的关键部分,如下所示:
<odc:ConnectionString>Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist
Security Info=True;Data Source=develop;Use Procedure for Prepare=1;Auto Translate=True;Packet
Size=4096;Workstation ID=DEVELOP;Use Encryption for Data=False;Tag with column
collation when possible=False;Initial Catalog=K0712</odc:ConnectionString>
<odc:CommandType>Table</odc:CommandType>
<odc:CommandText>"K0712"."
dbo"."ICInventory"</odc:CommandText>
其中,odc:ConnectionString是数据库连接串,使用和ADO一样的格式,不用多说了吧J;odc:CommandType是查询类型,Table是表查询,SQL是标准SQL语句查询;odc:CommandText是查询命令文本,如果是Table类型的,就只要写出表名称就可以了,如master.dbo.sysobjects,如果是SQL类型的话,就是一般的SQL语句,如
SELECT t0.*FROM ICStockBill t0 INNER JOIN ICStockBillEntry t1 ON t0.FStockBillID=t1.FstockBillID ORDER BY t0.FStockBillID
