Question

我的图书馆系统遇到了困难。我收到一个错误，指出“错误数据库：INSERT INTO语句中的语法错误”。我正在使用Access作为数据库。这是我的代码：

Public Class Form7
    Private Sub Form7_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
        Me.Text = "Registration"
        sqlCon.Close()
        sqlCon.Close()
        clear()
    End Sub

    Private Sub Form7_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Split(Me.Text, " - ")(1) = "Edit" Then
            sqlSTR = "Select * From BookRegister WHERE id = " & globalID
            ExecuteSQLQuery(sqlSTR)
            If sqlDr.Read Then
                TextBox1.Text = sqlDr(1)
                TextBox2.Text = sqlDr(2)
                TextBox3.Text = sqlDr(3)
                TextBox4.Text = sqlDr(4)
                TextBox5.Text = sqlDr(5)
                TextBox6.Text = sqlDr(6)
                TextBox7.Text = sqlDr(7)
                TextBox7.Text = sqlDr(8)

            End If

        End If
    End Sub

    Private Sub TextBox6_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox6.TextChanged

    End Sub


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

            globalID = 0
            edit = False
            Me.Close()
        End If
        FillListView(Form6.ListView1, ExecuteSQLQuery("select * from bookregister"))

    Private Sub clear()

        TextBox8.Text = ""


    End Sub
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Me.Close()

    End Sub
End Class

Answer 1

看起来你在INSERT语句的末尾缺少一个最后的单引号，然后在右括号后附加一个无关的双引号，即

& "','" & TextBox8.Text & ")"""

应该是

& "','" & TextBox8.Text & "')"
