Excel中VBA编程学习笔记（十五）--Access数据库删除操作

【例1】使用Connection对象的Execute方法删除数据

数据库格式:

Sub test()

    Dim conString$, sqlString$

    Dim cnn, rst

    Set cnn = CreateObject("ADODB.Connection")

    Set rst = CreateObject("ADODB.Recordset")

    Dim i%, sex$, Address$, Name$, birthDay$

    conString = "provider=Microsoft.ace.OLEDB.12.0;Data Source=" & ThisWorkbook.Path & "\test.accdb;"

    cnn.Open conString

    sqlString = "delete from students where sName='张三'"

    cnn.Execute sqlString

    MsgBox "删除成功"

    cnn.Close

End Sub

【例2】使用Recordset删除数据

数据表字段如下：

Sub exercise()

    Dim cnn ', rst

    Set cnn = CreateObject("ADODB.connection")

    'Set rst = CreateObject("ADODB.recordset")

    Dim rst As New ADODB.Recordset

    Dim sqlStr$, conStr$

    conStr$ = "provider=Microsoft.Ace.OLEDB.12.0;Data Source=" & ThisWorkbook.Path & "\test.mdb"

    sqlStr = "select * from students where 总分 <161"

    cnn.Open conStr$

    rst.Open sqlStr, cnn, adOpenDynamic, adLockOptimistic

    Do Until rst.EOF

        rst.Delete

        rst.MoveNext

    Loop

    cnn.Close

End Sub
