引用 Microsoft ActiveX Data Objects 2.8 Library
或者加入microsoft ado data control
定义数据库连接
Dim Cnn As New ADODB.Connection
定义操作记录
Dim Res As New ADODB.Recordset
开始使用
If Res.State = 1 Then Res.Close
Res.CursorLocation = adUseClient
Res.Open "SELECT * From 发票表", Cnn, adOpenDynamic, adLockReadOnly
删除用res.Delete
添加用res.AddNew
res.Fields("序号") = Trim(Res.Fields("序号"))
...
res.Update
更新用Res.Update "序号", 111
列：
'写入产品信息
Sub WriteFP()
'On Error Resume Next
Dim SyBaseRes As New ADODB.Recordset
PB.value = 0
Res.Open "SELECT Count(*) From ICSaleEntry INNER JOIN t_Item ON ICSaleEntry.FItemID = t_Item.FItemID INNER JOIN t_MeasureUnit ON ICSaleEntry.FUnitID = t_MeasureUnit.FMeasureUnitID", SQLServer, adOpenDynamic, adLockReadOnly
