ADO RecordCount 属性


❮ Recordset 对象完整参考

RecordCount 属性返回一个长整型值,表示 Recordset 对象中的记录数。

如果 Recordset 对象支持 AbsolutePosition 和 AbsolutePage 属性或书签(如果 Supports(adApproxPosition) 或 Supports(adBookmark) 返回 true),则此属性将返回 Recordset 中的精确记录数。

注意:对于仅向前游标,此属性将返回 -1;对于静态或键集游标,将返回实际计数;对于动态游标,将返回 -1 或实际计数。

注意:调用此属性时,Recordset 对象必须处于打开状态。如果此属性不受支持,则将返回 -1。


语法

objRecordset.RecordCount

示例

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open(Server.Mappath("northwind.mdb"))

set rs=Server.CreateObject("ADODB.recordset")
sql="SELECT * FROM Customers"
rs.Open sql,conn

if rs.Supports(adApproxPosition)=true then
  i=rs.RecordCount
  response.write("The number of records is: " & i)
end if

rs.Close
conn.Close
%>
