Question

这是我用于尝试向我的数据集插入行的代码。它会正确执行，直到打开sqlConnection。但是，nonQuery执行会抛出一个System.Data.SqlClient.SqlException＆＃39;我相信我的连接字符串有问题，我从app./config文件中复制它，我无法弄清楚出了什么问题。另外，我知道我应该使用参数化的SQL查询，稍后我会实现它。

    Dim sqlConnection1 As New System.Data.SqlClient.SqlConnection("Data Source=(localdb)\MSSQLLocalD;Initial Catalog=ContactInfo;Integrated Security=True;Pooling=False")
    Dim cmd As New SqlClient.SqlCommand
    cmd.CommandType = CommandType.Text
    cmd.CommandText = "INSERT INTO Table (ID, FirstName, MiddleName, LastName, Type, Telephone, Extension, Email) VALUES (" + row.ID.ToString + "," + "'" + row.FirstName + "'" + "," + "'" + row.MiddleName + "'" + "," + "'" + row.LastName + "'" + "," + "'" + row.Type + "'" + "," + row.Telephone.ToString + "," + "'" + row.Extension + "'" + "," + "'" + row.Email + "')"
    cmd.Connection = sqlConnection1
    sqlConnection1.Open()
    cmd.ExecuteNonQuery()
    sqlConnection1.Close()

Answer 1

首先，不要以为你可以为你的餐桌命名＆＃34;表＆＃34;所以将其更改为您的真实表名称，它应该运行并使用SQL参数！

其次，将ExecuteNonQuery的结果输入变量，以便检查是否写入了记录。
