你好我在我的数据库中保存记录时遇到问题,当我调试程序时,它表示" OLEDB Execption未处理,更新语句中的语法错误" 你能帮助我吗?
这是正确的代码吗?
Imports System.Data.OleDb
Public Class Form2
Dim contr As String = "Provider= Microsoft.Jet.OLEDB.4.0; Data Source= C:\Users\Administrator\Desktop\Users.mdb;"
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim con As New OleDbConnection(contr)
con.Open()
Dim cmd As New OleDbCommand("UPDATE Usertable SET Username = @Username, Password = @Password WHERE id = @id", con)
cmd.Parameters.AddWithValue("@Username", TextBox1.Text)
cmd.Parameters.AddWithValue("@Password", TextBox2.Text)
cmd.Parameters.AddWithValue("@Id", Label3.Text)
cmd.ExecuteNonQuery()
con.Close()
End Sub
End Class

Access / OLE不喜欢命名参数。您需要使用?
占位符:
UPDATE Usertable SET Username = ?, Password = ? WHERE id = ?
然后,要将每个参数值与占位符匹配,必须按照查询中使用占位符的顺序将它们添加到Parameters集合,而不是按名称添加。
