我收到了这个错误：

语法错误INSERT INTO语句

这是正确的另一个是SQL抱歉

//Server Connection
private void ServerConnect()
{
    string ConnString;
    ConnString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=PLAN.accdb";
    TConn = new OleDbConnection(ConnString);
    TConn.Open();
    MessageBox.Show("You Are Connected.");
    TConn.Close();
}

//ADD MEMOS
private void GetMemoList()
{
    string query;
    DataSet ds = new DataSet();
    query = "SELECT MEMO_ID,DATE,TIME,MEMOS FROM TBLMEMO ORDER BY DATE ASC";
    OleDbDataAdapter da = new OleDbDataAdapter(query, TConn);
    da.Fill(ds);
    this.dgv1.DataSource = ds.Tables[0];
}

private void AddMemo(string MemoDate, string MemoTime, string Memos)
{
    TConn.Open();

    string acc;
    acc = "INSERT INTO TBLMEMO (DATE,TIME,MEMOS) VALUES (@Memodate,@MemoTime,@Memos)";
    OleDbCommand cmd = new OleDbCommand(acc, TConn);
    cmd.Parameters.AddWithValue("@memDate", MemoDate);
    cmd.Parameters.AddWithValue("@memTime", MemoTime);
    cmd.Parameters.AddWithValue("@memos", Memos);
    cmd.ExecuteNonQuery();
    TConn.Close();
}

private void btnAddMemos_Click(object sender, EventArgs e)
{
    AddMemo(this.dtpDate.Value.ToShortDateString(), this.dtpTime.Value.ToShortTimeString(), this.txtInfo.Text.Trim());
    GetMemoList();
    txtInfo.Clear();
}

Answer 1

表的主键可能未设置为自动增量

Answer 2

表TBLMEMO中可能包含三个以上的字段，但您只插入了3个字段。这就是为什么你会收到这个错误“查询值和目标字段的数量不一样。”

尝试

"INSERT INTO TBLMEMO(COLUMNNAME1, COLUMNNAME2, COLUMNNAME3) VALUES ('" + MemoDate + "','" + MemoTime + "','" + Memos + "')";

Answer 3

尝试在查询中指定字段

acc = "INSERT INTO TBLMEMO (fld1Name, fld2Name, fld3Name) VALUES ('" + MemoDate + "','" + MemoTime + "','" + Memos + "')";

Answer 4

始终在INSERT语句中指定目标列。您还需要在语句中使用Parameters来避免Sql Injection攻击。

var acc = "INSERT INTO TBLMEMO (DATE, TIME, MEMOS) VALUES (@date, @time, @memos)";
TConn.Open();
var cmd = new SqlCommand(acc, TConn);
cmd.Parameters.AddWithValue("date", MemoDate);
cmd.Parameters.AddWithValue("time", MemoTime);
cmd.Parameters.AddWithValue("memos", Memos);
cmd.ExecuteNonQuery();
TConn.Close();

我收到此错误“查询值和目标字段的数量不一样。”
