: 请问我用ADO开启SQL之资料档<br>: connstr = "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=LONG3;Data Source=LONG-NT"<br>:    conn.Open connstr<br>:    rs1.CursorLocation = adUseClient<br>:    rs1.Open "商品主档", conn, adOpenKeyset, adLockOptimistic<br>:    Set DataGrid1.DataSource = rs1<p>: 资料大约2000笔为何需20-30秒<br>1.CursorLocation 设为adUseServer会较快<br>2.DataBase加上Index and open recordset 用<br>SQL ,记得SQL语法内要加Order By Field(index field)<br>3.DataGrid 加上 adUseClient 真的很慢,可考虑用Other Method  <br>
