你只要将RecordSet的游标类型设置为客户端游标类型就行了: 设置cursorlocation=adUseServer 打开参数只有在为adopenstastic的情况下recordcont属性才能正确显示数据集中的记录值Recordset对象的游标类型会影响是否能够确定记录的数目。对仅向前游标,RecordCount性将返回-1,对静态或键集游标返回实际计数,对动态游标取决于数据源...
综上所述，通过合理调整ADO的属性设置，可以解决RecordCount总是返回-1的问题，同时提高程序的运行效率。在打开Recordset时，使用静态或键集游标类型（如adOpenStatic或adOpenKeyset）能确保获取正确的记录数，并避免性能瓶颈。

在打开记录集前还要做的工作有:声明Recordset对象,创建Recordset对象 Dim rsZYS As ADODB.Recordset Set rsZYS = New ADODB.Recordset rsZYS.Open "职员表", cnADO, 1, 3 MsgBox rsZYS.RecordCount rsZYS.Close cnADO.Close Set rsZYS = Nothing Set cnADO = Nothing 上述语句中代码 ① rsZYS.Open "职员表...
Recordset 对象的游标类型将影响是否能确定记录的数目。对于仅向前游标，RecordCount 属性将返回 -1；对于静态或键集游标，将返回实际计数；而对于动态游标，则返回 -1 或实际计数，这取决于数据源。关于记录数量太多:如果 Recordset 对象支持近似定位或书签（即 Supports (adApproxPosition) 或 Supports (ad...
