Question

我试图在asp.net表单上插入代码，

我有两张桌子：表培训 training_id training_Date 。

表人培训 ID training_id 名称，部门

我做错了吗？

我需要从表单中插入值，另外，从查找表中选择值，其中training id等于下拉列表选择值。

private void InsertInfo()
    {

        SqlConnection conn = new SqlConnection(GetConnectionString());
        string sql = "INSERT INTO personTraining (name,training_id,training,trainingDate.trainingHour,trainingSession)  VALUES (@Val1,SELECT (training_id,training,trainingDate.trainingHour,trainingSession FROM tbl_training WHERE training_id = dpDate.selectedValue))";
        try
        {
            conn.Open();
            SqlCommand cmd = new SqlCommand(sql, conn);
            cmd.Parameters.AddWithValue("@Val1", txtName.Text);
//will add rest of form fields

            cmd.CommandType = CommandType.Text;
            cmd.ExecuteNonQuery();
        }

Answer 1

您需要使用类似

的内容

INSERT INTO personTraining
            (name,
             training_id,
             training,
             trainingDate.trainingHour,
             trainingSession)
SELECT @Val1,
       training_id,
       training,
       trainingDate.trainingHour,
       trainingSession
FROM   tbl_training
WHERE  training_id = dpDate.selectedValue

你不能有这样的混合VALUES子句/ SELECT声明。

Answer 2

试试这个：

INSERT INTO personTraining (
    name,
    training_id,
    training,
    trainingDate.trainingHour,
    trainingSession)  
SELECT 
    @Val1,
    training_id,
    training,
    trainingDate.trainingHour,
    trainingSession 
FROM tbl_training tt 
WHERE training_id = dpDate.selectedValue

插入错误：关键字'SELECT'附近的语法不正确
