我正在尝试更新客户信息。我使用此代码加载5个字段:
cust_cn.Open()
Dim cust_da As New SqlDataAdapter("SELECT * FROM [customers] where [custID]=" & txtCustPhone.Text, cust_cn)
cust_da.Fill(cust_datatable)
txtCustPhone.Text = cust_datatable.Rows(0).Item("custID")
txtCustFirstName.Text = cust_datatable.Rows(0).Item("first")
txtCustLastName.Text = cust_datatable.Rows(0).Item("last")
txtCustAddress.Text = cust_datatable.Rows(0).Item("address")
txtCustZip.Text = cust_datatable.Rows(0).Item("zip")
这很好用。当我尝试修改其中一个字段时(更改现有客户的邮政编码) 使用此代码:
If cust_datatable.Rows.Count <> 0 Then
cust_datatable.Rows(0).Item("custID") = txtCustPhone.Text
cust_datatable.Rows(0).Item("first") = txtCustFirstName.Text
cust_datatable.Rows(0).Item("last") = txtCustLastName
cust_datatable.Rows(0).Item("address") = txtCustAddress.Text
cust_datatable.Rows(0).Item("zip") = txtCustZip.Text
'cust_datatable.Rows(custrecord)("custID") = txtCustPhone.Text
'cust_datatable.Rows(custrecord)("first") = txtCustFirstName.Text
'cust_datatable.Rows(custrecord)("last") = txtCustLastName.Text
'cust_datatable.Rows(custrecord)("address") = txtCustAddress.Text
'cust_datatable.Rows(custrecord)("zip") = txtCustZip.Text
cust_DA.Update(cust_datatable)
End If
我收到错误:“字符串或二进制数据会被截断” 我最初尝试使用注释部分进行更新,但它只修改了数据库中的第一条记录。 有什么想法吗?
