sql - 使用 vb.net 将数据插入 SQL Server 数据库

问题描述

我创建了一个 SQL Server 数据库，我想在该数据库的特定表中添加一些数据。我使用一些文本框来输入数据并使用添加按钮来完成。但是当我点击按钮时，整个过程停止并指示 DBSQL 模块中的错误，如下所示。

这是我的代码：

Imports System.Data
Imports System.Data.SqlClient

Module DBSQLServer
    Public con As New SqlConnection("Data Source=JOYALXDESKTOP\SQLEXPRESS;Initial Catalog=SaleInventory;Integrated Security=True")
    Public cmd As New SqlCommand
    Public da As New SqlDataAdapter
    Public ds As New DataSet
    Public dt As DataTable
    Public qr As String
    Public i As Integer

    Public Function searchdata(ByVal qr As String) As DataSet
        da = New SqlDataAdapter(qr, con)
        ds = New DataSet
        da.Fill(ds)
        Return ds

    End Function

    Public Function insertdata(ByVal qr As String) As Integer

        cmd = New SqlCommand(qr, con)
        con.Open()
        i = cmd.ExecuteNonQuery()
        con.Close()
        Return i

    End Function
End Module

错误发生在这一行：

i = cmd.ExecuteNonQuery()

错误是：

System.Data.SqlClient.SqlException：'')'附近的语法不正确

这是我的添加按钮代码：

Private Sub Add_Click(sender As Object, e As EventArgs) Handles add.Click
        If (isformvalid()) Then
            qr = "Insert into tblProductInfo (ProName, ProDesc, ProPrice, ProStock) Values('" & nametext.Text & "','" & descriptiontext.Text & "','" & pricetext.Text & "','" & stocktext.Text & "',)"
            Dim logincorrect As Boolean = Convert.ToBoolean(insertdata(qr))
            If (logincorrect) Then
                MsgBox("Stock Added Successfully ...", MsgBoxStyle.Information)
            Else
                MsgBox("Something Wrong. Record Not Saved. Please Check and Try Again...", MsgBoxStyle.Critical)
            End If
        End If
    End Sub

当我复制该错误的详细信息时，它显示：

System.Data.SqlClient.SqlException
HResult=0x80131904
消息=')' 附近的语法不正确。
